New Drone Partnership Close to Home

Droneflight and QuestUAV: A New Partnership.

"<yoastmark

Droneflight is taking on QuestUAV products that will expand its current foreshore survey work.  Droneflight’s Head Quarters is less than 40 miles South of QuestUAV’s Manufacturing Base. The advanced QuestUAV PPK Datahawk aircraft will complement their current range of multirotor drones.

 

QuestUAV embarked on a lengthy Research and Development project spanning 3 years to enable the Datahawk to perform with Post Processing Kinematics (PPK) to deliver Ultra High-Accuracy Precision. The Datahawk PPK has had a good response all over the world so no surprise that a company on their door step was interested in the product.

Partnership:

Nigel King, CEO of QuestUAV, said ‘The Datahawk PPK is a great little aircraft and very well priced; I’m sure this fixed wing choice by Droneflight will help them move forward quickly and with minimum outlay. Andrew of Droneflight said he wanted a fixed wing tough enough and ugly enough to take a good beating; he won’t be disappointed”

 

Andrew Griffiths, CEO of Droneflight said ‘Working with QuestUAV was a just a sensible business decision. They are a UK based manufacturer so liaison, training and repairs are more easily managed than with a foreign company. We do a lot of foreshore work where PPK is ideal, so the Datahawk PPK, with its attractive pricing and rugged capability, made it a winner for us.’

 

The Datahawk PPK carries the highly regarded Septentrio Asterex L1/L2/L2/L5 with GPS, GNSS, GALILEO, BEIDOU and others. With the most advanced antijamming technology on the market it is integrated at a price point into the Datahawk that is placed well below the competition.

 

For UK and European customers within reach of QuestUAV training centre, it can make a big saving when entering the single operator, fixed wing, PPK market.

 

Droneflight also has a training division, DronePartners that is a CAA NQE and provides specialist inspection and PIX4D training.  The partnership will explore training opportunities for both companies.

QuestUAV:

QuestUAV is the longest running fixed wing manufacturer based in the UK.  They Design, Build and Fly small fixed wing unmanned aircraft (sUAV) that carries sensors including high-resolution cameras, infrared, thermal, multispectral and video surveillance.  Their network of clients spans across 6 continents and contains strong links with World-Leading Universities and Research institutions.

Gas Sensor Takes Flight on UAV

Remote sensing of atmospheric gas concentrations is important in monitoring global greenhouse gas levels and industry monitoring. Monitoring is usually carried out via satellite sensing or laborious ground-based measurements.

With aerial measurement, a wider area can be measured efficiently, and repeat measurements taken of days, weeks and months gathering time-series data.

BGS Gas Sensor Q200

This spring, a study by QuestUAV and the British Geological Survey (BGS) used a custom QuestUAV Q200 airframe equipped with two sensors, one tuned for methane (CH4) and one for CO2. The sensors use an open-path gas mass spectrometer — a fiber-guided laser beam passed laterally across open atmosphere on top of the drone to a reflector and then back to the sensor itself.

Signals from the sensors were fed into a multi-core processing unit on board the drone. All readings were stamped with time and location provided by the standard GPS and flight units in the Q200.

The completed drone was commissioned in March. Over several months, trial flights were run over gas releases initiated manually on the ground over the test site. The recorded sensor data was processed immediately on return to base, and the data passed to BGS for analysis and appraisal.

The team plans to fine-tune the operational workflow and maintenance tasks for regular missions.

Papa Mamadou came from Senegal on a mission to learn how to operate the QuestUAV Surveyor Pro on his Grand Cote mines. A great character, full of smiles and fun, he braved the roughest of English weather and Storm Doris to complete his training with us.  

Some quotes from him both in English and his native French tongue.  

“Wonderful good great I enjoyed my time"

"Javoue vraiment davoir passer d’excellent monments avec l’equipe QUESTUAV. Cetait une occasion pour moi de decouvrir northumberland et decouvrir aussi lhospitalite anglaise. Du professionalisme et de lexcellence chez Quest UAV et lhistoire ne fait que commencer sachant que nous avons un grand chemin a parcourrir ensemble.”-Papa

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.
