QuestUAV Provide Own PPK Solution For Q-200

QuestUAV Provides Own PPK Solution For Q-200 Surveyor UAV


 

QuestUAV Own PPK

PPK (Post-Processing Kinematic) provides much higher accuracy in GPS location when stored against images taken in a UAV. Standard GPS signals are accurate to 10's of metres - PPK increases that accuracy to cm-levels. On board the Q-200 UAV, PPK eliminates the need for physical Ground Control Points (GCP) that are often used to gain high accuracy in surveys. This saves hours of mission planning and setup time, physically measuring location points and walking the survey site for placement.


 

GCPs – The underestimated part of a UAV survey

Surveys involving GCP generally run like this:

  • Initial site is viewed to establish useful locations for Ground Control targets.
  • Each location is visited with a GCP and a Differential GPS receiver to accurately place the target.
  • Targets may need revisiting before survey takes place.
  • Locations are stored for post processing reference.

In most cases - up to half of the mission time is taken up with GCP placement. GCP targets may shift or collapse with changing weather conditions – requiring the original placement to be repeated (often wasting up to an hour of survey setup time); coastal surveys can suffer from tidal changes and cliffs make it difficult to place GCPs across the survey area; general survey ground conditions can make it difficult to secure GCPs - quarries are a good example of difficult, variable ground surfaces.


 

The advantage of PPK - Overcoming GCPs

The PPK solution offered by QuestUAV uses a higher performance, highly-accurate receiver placed within the aircraft - following more than 10 GPS satellites at any given time and storing location information against the triggered images taken. Combined with differential signal information collected by the fixed position Ground Station (which stores signal drift and signal error values), the image locations are recalculated to a much higher accuracy – down to centimetre level in x, y and z direction.

QuestUAV Own PPK

Compared to RTK (Real Time Kinematic), PPK also eliminates the need for a real-time data link with a fixed reference station during the flight, whilst guaranteeing RTK cm-level position accuracy of the images once post-processing has taken place, after the UAV lands. This simplifies the UAV set-up, reduces the requirements and power drain on-board and eliminates any loss of accuracy in data due to potentially unreliable radio links - which often plague RTK UAV operations.

The Q-200 Surveyor Pro is available with PPK at purchase or as an upgrade to an existing aircraft with the provision of just the PPK QPod.

Long Range MicaSense Agronomy Surveys


Long Range MicaSense RedEdge Agronomy Surveys


Q-200 and Q-100 Aircraft Are Put Through Their Paces In Agricultural Survey

Long Range Flight Op

This long range agronomy survey was part of a mission in the English countryside. We regularly fly test and demonstration missions across the UK. A multiple airframe survey demonstration flown for Hummingbird Technologies was no exception.

The survey took place over 2 days, with both a Q-200 AGRI MicaSense UAV and a Q-100 DATAhawk MicaSense UAV. Each airframe is equipped with the MicaSense RedEdge multispectral sensor suite, capable of detailed multiband imaging across 5 discrete spectral bands.


DAY 1


Aerial Field

The survey site consisted of agricultural research samples and was imaged using both airframes using a 3-person flight team - 1 pilot, 1 commander and 1 spotter/driver for mobile operations.

On day 1 the Q-100 DATAhawk missions were repeated at different altitudes to demonstrate flight performance and MicaSense image quality. The DATAhawk covered 325Ha during a 42 minute flight at 400ft with a 70% overlap.

 


 

Day 2

Day 2 missions were designed to showcase the endurance of both the Q-100 DATAhawk and the similarly RedEdge-equipped Q-200 UAV. The Q-200 required only two flights to cover 730Ha at 400ft with 70% overlap. Parachute landings were performed in each case with a 46 minute flight time (per flight). Mobile ops were used to ensure Line of Sight requirements were adhered to.

Final Analysis

Once processed, the imagery from both days' missions will form the basis of high quality NDVI and RedEdge Indices, which will be correlated and compared with agricultural information, such as LAI (Leaf Area Index), crop density and nitrogen uptake.

Clients on-site were very pleased with the endurance and performance of both the Q-200 and the Q-100 DATAhawk, especially when considering the high winds that were present during the surveys days.

Still Flying After 3000km – The Incredible Story of Mango Six | QuestUAV News

AN INDESTRUCTIBLE QUESTUAV “SURVEYOR” THAT FLIES WEEKLY MISSIONS THROUGHOUT SOUTH KOREA AND ASIA

After 3,000 kilometers and 200 hours in the sky, Q-200 Surveyor “Mango Six” is still far away from retirement


 

MANGO SIX - AN AMAZING DRONE

Mango Six is a Flagship of the QuestUAV fleet and commercial drone world. It continues to perform faultlessly, under highly demanding survey conditions with its commercial owner in South Korea, in different countries, different weather conditions, managing rough environments and whatever life throws at it day after day. It goes on and on. So what makes the difference that creates another legend like Mango Six? Is it luck? Or Divine Intervention? Or are there other factors involved? Read on to discover some of its history and the reasons behind its success.


 

CHAPTER 1 – SOUTH KOREA WANTED A WORLD CLASS LEADER


 

A two year search by the major government-based South Korean land survey department to find a suitable fixed wing drone for their survey needs resulted in an invitation to UAV suppliers from all over the world. Their request was simple: Be the best and the most accurate at surveying a large test site in the heart of Korea, where engineers had prepared millimetre accuracy targets. The submitted result had to be a computer based map of similar accuracy but in a jaw dropping size - covering over 1 square kilometre. Inaccuracies of any note would not be costly to entrants.

Incredible Mango Six

Survey team and jury after a successful demonstration of our Q-200 Surveyor

The agency, LX, Korea Land and Geospacial InformatiX Corporation, (similar to Ordnance Survey in UK) wanted to find out how accurate each competitor was and how usable design was in order to roll out to each of its twenty six regions in South Korea. The QuestUAV partner in South Korea, HOJUNG Solutions Co. Ltd, were keen to display the capabilities of the QuestUAV 2m wingspan drone, with its gimballed camera.

Though QuestUAV were last to present from the global lineup of competitors, it soon became evident that QuestUAV held the winning design and what was then to become MANGO SIX was ordered. Training was conducted both in UK and in South Korea for a series of complex surveys.

Details of the performance demonstration for LX are here.

CHAPTER 2 – TRAINING, CREW AND MANGO SHAKES


 

After passing LX’s accuracy test, the QuestUAV trainer team spend two weeks in South Korea to prepare the new flight crew of Hojung Solutions for their upcoming surveys. The team, led by Munseok Lee (second from right) received special training on mobile operations and corridor surveys.

After long hard training days, QuestUAV trainer Nigel and the crew rewarded the daily progress in the famous coffee bar - Mango Six. Mango Six became the team's relaxing oasis, briefing room and training headquarters in one. Ten mango shakes later, the crew decided to title their Q-200 Surveyor “Mango Six”. Who would have thought at that time that Mango Six would become one of the most famous UAVs in Asia?

Nowadays, the highly motivated team of Hojung Solutions consists of 3 pilots and 2 commanders accepting the most challenging survey requests.

CHAPTER 3 – 300 KM ROAD CORRIDOR


 

As a result of the great performance during at the flight demonstration, QuestUAV and Hojung Solutions were awarded a contract for a 300 km road and corridor survey for LX. The project had already been given to an Australian contractor, but when it became apparent that Hojung/QuestUAV partnership could do a much better job with a Q-200 Surveyor, the contract was reassigned.

The survey was conducted in the Jeollabuk-do province, in the southwest of South Korea, in October 2015. The 300 km road corridor, including routes in mountains and through tunnels, was flown with Mango Six, equipped with a Sony A6000 camera, over a period of one month. While Mango Six was taking high-resolution imagery from 400ft, the flight crew followed the route on the roads being surveyed in their vehicles. In order to also cover the road-sides, Mango Six flew a few extra lags for a combined mission length of 1,280 km. One intended purpose of the collected data is to allow government departments to determine illegal land use along road-sides.


 

CHAPTER 4 – UAV STANDARD VERIFICATION

Incredible Mango Six

QuestUAV's successful entry into South Korea in the news

South Korean authorities are very strict in their UAV verification standards - much higher than the European CE standards. On average, it takes six months for equipment to pass the equivalent verification in South Korea. Once verified, products can be released for general use.

LX clearly required verification, and to the credit of Munseok Lee and QuestUAV collaboration, Hojung managed to pass South Korean verification in a record breaking one week. Prior certification to operate QuestUAV models in UK, Europe, America, Canada, and Australia helped speed up the process.

Since verification, the South Korean authorities were so impressed by our technology and safety standards that QuestUAV is now the reference standard for fixed wing drones in the country.


 

CHAPTER 5 – OUR RÉSUMÉ AFTER ONE YEAR


 

From maiden flight up until today, Mango Six has spent more than 200 hours in the sky and covered a distance of 2,929
kilometers.

The Q-200 Surveyor has been used for a vast variety of applications, ranging from cadastral surveys, to inspection missions, to archaeological site mapping through to flying over festivals (Muan-gun Lotus festival) and stadiums (Yeongam-gun F1 Formula Stadium).

The teams at Hojung Solutions are now busier than ever, currently conducting a large survey mission with a Q-100 DATAhawk in Tanzania. Mango Six, in the meantime, is joined by three other Q-200 Surveyor drones and two Q-100 DATAhawks, all producing great results for the clients of Hojung So.

Congratulations Team GGP for Successfully Completing the QuestUAV Training


After Seven Days Intensive Flight Training The GGP Team Is Ready For Their First Survey Adventure


30,000 Hectares of Tropical Fruits Need To Be Mapped!

Q200 GGP in Flight

More Than 25 Takeoffs And Landings

After seven days of intensive training, the flight crew at GGP (Great Giant Pinapple) is ready to complete their own flight missions without supervision of the QuestUAV trainers. During the past week the team has practiced the whole mission workflow over and over again, including not only flight practice but also safety assessment, flight planning, site setup, UAV maintenance, camera preparation and data extraction.

The two Q-200 Agri-Pros have been launched and landed more than 25 times. The GGP crew has learned how to fly in different modes (auto and assisted) and how to land their QuestUAV drones with both methods, parachute and belly landing, on different surface types (matured pineapple, young pineapple, knocked down fields, roads).


 

Q200 Drone GGP

A Big Mission Ahead

The QuestUAV training was just the start of a larger survey mission and certainly a busy time for the new flight crews. 30,000 hectares of pineapple, banana and other tropical fruits are waiting to be mapped by the crew and analysed by GGP's agricultural and GIS experts.

UAV images, especially NDVI maps, will be used for the assessment of plant vigor and crop status, disease detection and identification of canopy gaps. Further, UAV-based elevation models will become the basis for developing a better drainage system for the entire plantation.


 

Thanks To All Helping Hands

The QuestUAV team, especially our trainers Nigel and Stuart, would like to thank GGP for their outstanding hospitality and the dedication of the whole crew to make this training week a success. Special thanks goes to Nanda Pratama (himself a QuestUAV pilot in Indonesia) for his translation work and training support.

Nigel and Stuart, now on the way back home, will bring many impressions and perspectives back to the QuestUAV workshop and we are looking forward to hear more stories from Indonesia.

QuestUAV Images Make UNESCO World Heritage Sites Perceptible For Visually Impaired People

An Image-Based Model of an Amphitheater Amazes Visitors at Ancient Kourion, Cyprus


The ancient city-kingdom of Kourion is an impressive archaeological park on the southwestern coast of Cyprus and part of the UNESCO World Heritage Site of Paphos. The park has a pretty visitor center, where interested people can experience history in a lively way.

In 2014, the British drone manufacturer QuestUAV, in cooperation with the Cyprus University of Technology, flew the archaeological park with one of their Q-200 Surveyor drones. Pix4Dmapper Pro was used to translate the acquired high resolution aerial images into a virtual 3D model. Sections of this virtual model were printed in 3D and can now be discovered by visually impaired people at the visitor centre.

About the Survey


The QuestUAV team flew the archaeological park with one of their Q-200 Surveyor drones, equipped with a Sony A6000 camera and a 16mm wide angle lens. A total area of 100 ha was flown at 400 ft. A team of two was used for the survey – a pilot and a laptop commander.

330 aerial photographs were taken during a 20 minutes fully autonomous flight. The automatic camera trigger and the gimballed camera system allowed us to take pin sharp pictures even at high wind speeds of up to 40 km/h.

The images have a ground sampling distance (GSD) of 2.5cm with an overlap of 80% in-flight direction and 65% sidelap. At the same time, the Q-200 Surveyor recorded the GPS coordinates of each camera position in a log file, allowing for geo-locating the images on the earth. The entire survey from flight planning, through autonomous flight and culminating in parachute landing took no longer than an afternoon.


Image Processing and 3D Print


UAV images and log file were the basis for creating a high resolution geo-referenced orthomosaic and a virtual 3D model of the entire archaeological park. The image products were generated in Pix4Dmapper Pro, a professional photogrammetry software for processing aerial imagery.

The survey results have been primarily used to create archaeological site maps of the ancient city of Kourion with a never seen level of detail. The team around the Cyprus University of Technology and the Cyprus Department of Antiquities was impressed by the quality of the 3D model and the performance our Q-200 Surveyor drone.

Pix4D Software

In summer 2015, the park administration came up with the fantastic idea to use sections of the virtual 3D model, like the amphitheatre, as template for physical exhibition models in the visitors’ centre. The exhibition models are printed in 3D on the basis of the virtual dataset. Nowadays the models are surrounded with Braille annotations and explanations allowing those who are visually impaired to interactively experience the history of Kourion.

Technology Advantages

Over the last few years, UAV surveys became an important method to analyse archaeological sites and to help keeping cultural heritage. UAV-based 3D models allow archaeological experts and other interested people to virtually visit and analyse ancient places. 3D print-outs are a wonderful way present mapping results and to educate the public at exhibitions or visitor centres. Combined with Braille explanations, printed 3D models make historical places perceptible for visually impaired people.

About the Ancient City of Kourion

Kourion was an ancient city-kingdom on the southwestern coast of Cyprus and an urban center of considerable importance. The most ancient remains in the area are connected with settlements and tombs of the Ceramic Neolithic period (circa 5500-4000 BCE). The majority of the archaeological remains within the Kourion Archaeological Area date to the Roman and Early Byzantine periods. They include several buildings with well conserved floor mosaics. All archaeological remains within the area are managed and administered by the Cyprus Department of Antiquities.

Q-200 AGRI Pro International Training Continues Apace in Indonesia


QuestUAV Training Team Starts Large-Team International Training with the Q-200 with GGP


One of QuestUAV Ltd's flight training teams arrived in Indonesia this past weekend, to provide in-country training for GGP (Great Giant Pineapple). Sunday saw the completion of a successful series of test flights with Q-200 AGRI Twin NDVI aircraft.

Q200 Indonesia

Training began in earnest yesterday and today saw the first flights with the flight teams in-country. Some 18 people from these teams (and other GGP staff with a need to understand the technology) are taking part in QuestUAV international training within Indonesia this week.

Q200 Indonesia

Project Background


GGP grow a majority of premium Pineapple crop, although they are also responsible for Banana, Palm Oil and Casava plantation areas and a growing segment of other tropical fruits. The plantations are over 30,000 Ha in area. UAV images and the UAV project are phase one of GGPs initiative to integrate precision agriculture firmly within their growing processes. Phase 1 of this initiative are the UAV flight, monitoring and image collection missions that this current training is enabling. Phase 2 will see GGP purchase large GPS-driven farm machinery to make use of the GIS output provided by the teams in Phase 1.

Learn How the QuestUAV Team Conducts the Annual Overhaul of an Intensively Used Q-200 Agri-Pro


 

The Dole crew on the Philippine island of Mindanao is certainly one of the busiest QuestUAV flight crews ever. They continuously fly the fields of the worlds largest pineapple plantation with two of our Q-200 Agri-Pro drones.

They acquire aerial images for a variety of applications, such as topographic surveying, erosion measurements, disease mapping and growth monitoring.

After more than 200 successful take-offs and landings, Dole has sent their much loved “Agila” back to QuestUAV for an annual overhaul. This overhaul was to include inspection, upgrades and replacements. Within three days of arrival of the kit in UK they would expect to get a full upgrade.

Q200 Annual Inspection

After receiving the UAV, we start with a general inspection of the equipment.

We start the overhaul with comprehensive checks of the general condition of the whole UAV system, including A-frame, wings, cameras and flight laptop. All components are photographed and recorded. The initial assessment is important to estimate time and costs for repairs, upgrades and replacements.

Rather than replacing items wholesale, we make use of the modular QuestUAV design, retaining all parts that are still functional and in good condition. This method safes both costs for the end user and reduces unnecessary resources in the supply chain.


Then we start with the technical overhaul.

Q-Pod...

The Q-Pod is the UAV body and carries the system components, including: A-Block, cameras, gimbals and wings.

The modular design allows to easily replace and repair retired components without replacing the whole pod.

In this case the Q-Pod had received a lot of wear and tear from rough landings on the plantation. A new one, complete with upgrades made over the past year, was drawn off the shelves and prepared for integration. The upgrades included reinforced sideplates, lighter gimbal, and slightly denser EPP foam. 


 

Q200 Annual Inspection

Avionics Block...

The Avionics Block (A-Block) is the heart of the UAV, which carries the motor and the autopilot system.

After assessing the condition of the A-block and carefully checking the autopilot, we again decided to upgrade the existing system rather than replace everything. The autopilot was still in perfect condition and, again, the modular design allowed to exchange components rather than replace the whole A-Block. We retained the autopilot, logger and receiver and integrated these components into the new generation of our A-block frame.

The new A-block provided a more powerful motor, an upgraded ESC providing more cooling and more battery efficiency, improved anti vibration mounts and improved wiring layout.


Wings...

After more than 200 landings in pineapple fields, though the wings would have carried on giving good service, we decided that the wings needed to be retired, if only to look better. They were replaced by a brand new pair of wings that were waiting in our stock (complete with new and more powerful digital servos). The old wings were immediately destroyed.

Q200 Annual Inspection

Adam assesses the wing condition (left). Nigel destroys the wings after the decision to replace them (centre). And Jon attaches the new wings to the Q-Pod (right).


Cameras and Gimbals...

Q200 Annual Inspection

The whole purpose of a flight with the Q-200 Agri-Pro is to acquire high quality images in visible light and near infrared. Therefore, cameras and camera gimbals went through a careful assessment and a functional test procedure.

After thorough testing and cleaning the Dole cameras are still classed as working perfectly – a testament to their design and protection. Only a new gimbal was required to continue to balance the camera movement during flight.

Testing and protocoling the functionality of the near infrared camera.

After two days of checks and an overhaul the UAV is ready for airtesting.

Before "Agila" can fly back to the Philippines, it has to pass our standard airtest for maiden UAVs, including take-off and parachute landing, flight in different modes (auto, assisted, manual) and several autopilot and telemetry checks. Agila passed all tests with flying colours and is ready to be shipped back to Dole Philippines.

Q200 Annual Inspection

The completely overhauled UAV was shipped back to the Philippines on the third working day.

The whole UAV overhaul, from receiving the package through receipt, assessment, repairs, replacements and airtesting took 48 hours – an important factor for a drone that is needed for constant use by the clients. Following documentation and export control the upgraded Q-200 Agri-Pro got repacked to its rugged box and was shipped back, on the third day, via an express UPS service , to the Dole team in Polomolok.

Q200 Annual Inspection

Adam and Ryan prepare the UAV for shipment (left). Carla is waiting for UPS to pick up the box in front of our workshop (centre). Box is handed over to UPS (right).


An aside...

Providing a fast turnaround comes with complications. One of the biggest is the weather and airtesting in whatever conditions the British weather throws at us. During this maintenance schedule we were experiencing unusually high winds for our late spring period.

At times like this we just get on and manage….. there is no time in our busy airtesting schedule to wait for ideal flying days and the QuestUAV fleet are designed to cope with all manner of weather conditions.

The image shows just how windy this day was. It has been worse!

Q200 Annual Inspection

Strong winds in Northumberland - 22 knots on average!

QuestUAV’s last survey in Cyprus has once again proven how easy it is to cover a large area (4 sq km) in a single flight with the Q-100 DATAhawk. The entire survey from flight planning, through the autonomous flight and culminating in parachute landing took no longer than an afternoon. The UAV images were processed and output to an orthomosaic and an elevation model - all within the intuitive image processing software - Pix4Dmapper Pro. The processed images were the basis for the generation of high quality topographic maps and a detailed hydrological analysis with the open-source GIS software, QGIS.

The whole workflow, from flight planning to flying the area with the DATAhawk through to image processing and GIS analysis, took no longer than 2 days. Our workflows are tested more than a hundred times - they are quick and very easy to use and can be learned by anyone needing to streamline their missions.
