QuestUAV Survey Port of Sunderland using PPK Datahawk

An RGB land survey at the Port of Sunderland used 1400 images to create a 150 hectare pointcloud and ortho image.

sunderland, port,

QuestUAV Ltd was commissioned to undertake an orthographic survey for the Port of Sunderland in the UK.  The 150 hectare survey used one of QuestUAV's Datahawk PPK fixed wing drones, equipped with a Sony RX100 RGB camera capable of a 3cm resolution at 400ft.  The survey took one day to complete, including travel induction, risk assessment and setup of Trimble base station.

QuestUAV was chosen due to its ability to image relatively large areas of land in a short time and process to a high standard using professional techniques that can be verified using classical survey methods.  The QuestUAV team of two CAA qualified pilots chose two different sites for launch and landing to keep the drone visible always.

When airborne, one pilot acts as remote drone controller and one acts as commander with laptop and telemetry communications, at all times the drone is kept in visual sight by at least one member of the team.

One geolocated high resolution image is taken automatically every 2 seconds by the drone.  The total flight time was 1hour and fifteen minutes in which total of one thousand eight hundred images were taken of which one thousand four hundred were used for the survey.

The final processed results were given to our client three days after the completion of the flights.  Post processing came next with the generation of a point cloud and ortho model.  The resulting survey accuracy was within 5cm absolute accuracy, based on 12 check points from around the survey area.

QuestUAV has a professional survey team that has operated for ten years. The company also manufactures fixed wing drones for commercial survey use around the world.

Jo Harris, female marketing consultant at QuestUAV wrote an article entitled “Drone Boys vs Drone Girls” on 21 Feb 2017.

SuasNews received a complaint following the publishing of the article complaining that the article was “flagrantly sexist, male-centric and benighted”.

The complainant went on the say “You owe your readers, both female and male, an apology for posting such a degrading article.”

The following is a statement from QuestUAV director Nigel King, defending the author of the original article “Drone Boys vs Drone Girls”.

Comment By Nigel King.  QuestUAV Director 

 

“Jo Harris, my marketing publicist, is a DroneGirl through and through, having been in the industry for five years now.

She was itching to write a piece on one of her favourite subjects; That woman have as much a right to a role in the drone world as anyone. (And by process of deduction that simply means as much as any man!).  

I gave her my blessing. And then hid under the desk….

Now we have a saying here in the North of England. Jo Harris “isn’t backward in coming forward”. It means she is pretty outspoken. Most DroneGirls are.

In fact let me tell you a little about my female staff in general…… the “DroneGirls” of QuestUAV.

Kerstin Traut, international drone operative, the smallest of my DroneGirls, can throw me to the ground quicker than anyone I know. Donna can organise accounts better than a Ninja warrior can dispatch enemy heads. Heather is fearless, loves her bright red lipstick and tells me I don’t work hard enough. Actually so does Jess, my grandaughter (part time worker).   Jo Harris looks after a family of five and still manages at least four days a week at work. Carla Taylor took one look at the picture of the guy that wrote the complaint and went “he’s cute’ and promptly sent a Linkedin invitation to him. Between them they do a hundred different jobs including, yes, drone stuff.

Don’t you love it that kind of variety and uniqueness? I do! Life wouldn’t be the same around here.

So, who was to know that Jo and her DroneGirl colleagues, in all their feminine uniqueness, would be then hailed as (I quote)

“Flagrantly sexist, male-centric and benighted”, degrading their own feminine uniqueness in a  “demeaning”, “sexual” and “callow” way.

For real? Having read the complaint, the members of the pink flight-line naturally looked at each other with that “very confused” look. And then took great interest in the writer of the complaint… Believe me, it’s a dangerous situation for a bloke to be in the middle of.

Their accuser is, it seems, a MALE drone business owner, unable to identify Jo’s sense of humour OR identity as a the DroneGirl who penned the article (Two pictures of her were in the article).

When I asked Jo for a statement on the validity of the complaint Jo said in typical Jo Harris simplicity….

“Idiot”.

The complainant has since requested to withhold his complaint from being published but has demanded an apology from SUAS news on behalf of the rest of the world.

Well, truly, to anyone who has been offended (only one that we can make out so far) we offer our genuine apologies. There is no offence made at all. We hope that any reader can read between the lines of humour to the real message that each DroneGirl is a professional and rightly treated (and paid) as such.

My message to Mr Fox is;   “Do you really want to take these DroneGirls own self expression and competence out of their own hands and protect them with some faux grandeur that you want to call anti-feminisim? If so I suggest you go and find a woman who doesn’t want to have a door opened for her and then don’t open the door for her. Just don’t try it on here. It’s not welcome.”

Kerstin, DroneGirl, also had something piercing to say.

“I’ve travelled the world, operating complex UAVs all over the world and done missions that Luke probably cant even dream about. I’m not an arrogant person. I know about my knowledge and my skills and therefore this article isn’t sexist at all. I feel like I am a professional UAV operator and this article was just an interesting way to show our take on DroneGirls in the industry. It was an ironic piece phrased in an unassuming way to show our presence in the drone world.”

QuestUAV Releases New High Performance (HP) Wings for DATAhawk


QuestUAV Releases New High Performance (HP) Wings for DATAhawk


DATAhawk Wings
DATAhawk HP Wings

With an increase in surface area of around 22%, out new HP wings are having a significant boost for users where high altitude and/or turbulence are key factors to overcome. The image shows the new (HP) wings in black and the standard wings in grey.

The wings are a straightforward retro-fit with no changes required to the standard DATAhawk.

The wings increase the ceiling of the DATAhawk to 10000ft and beyond and have the effect of reducing the stall speed; a benefit in turbulent conditions. The wings also improve launch capability in light winds.

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.
