Mauritania Sees Survey Company CTG Provide New Drone Services

An established survey company is now providing drone services in Mauritania.  Consulting Training Group (CTG) Topographie, based in the capital city of Nouakchott, has taken the lead from one of our Senegal based clients operating in the mining sector.

CTG  is aiming to take on the challenge of a 40,000ha high-resolution survey in the Eastern Mauritania region using DATAhawk PPK. The sheer size of the project would make a normal drone survey with ground control an impossible task due to the immense number of ground control required and the difficult, barren terrain. Hence the 3cm to 6cm geospatial resolution capable with the QuestUAV PPK technology brings this opportunity closer to reality.

The companies director, Cheikh Tijani Hamed, received his DATAhawk PPK fixed-wing drone during his official drone training in the United Kingdom in February 2019.

Mauritania is one of Africa’s newest oil producers and is rich in mineral resources such as iron and ore.  Mauritania is in North West Africa and the eleventh largest sovereign state in Africa, bordered by Algeria, Mali, Western Sahara and Senegal.  The largely desert country presents a cultural contrast, with an Arab-Berber population to the North and black Africans to the south.  Many of its people are nomads.

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.

Topcon (Beijing) Chooses QuestUAV for High Altitude PPK Fixed Wing Operations on the Tibetan Platea

Topcon (Beijing) Chooses QuestUAV for High Altitude PPK Fixed Wing Operations on the Tibetan Platea

Collaboration between ROCtec - Topcon (Beijing) and QuestUAV has resulted in a first-time PPK land survey in the mountainous area of Mudao in the district of Qinghai.  With 99.9% unambiguity at better than 5 cm accuracy, the results display the full potential of the civilian mapping UAS.

Flying at 700ft agl and almost 15000 ft above sea level, QuestUAV’s 2kg DATAhawk aircraft covered an area of 150ha in less than 15 minutes.

This short video charts the operation of the QuestUAV PPK DAThawk by the ROCtec team and it’s post processing output.

It demonstrates the capability of the aircraft to operate entirely successfully with PPK in high altitude conditions and remote areas with little or no local RTK network.

QuestUAV’s director, NIgel King, said “This is an example of a great aircraft being used by a great crew. Jiang Chao and his ROCtec team (Topcon Beijing) are proving to be formidable partners with an assertive stance, ready to capture a new fixed wing drone survey market in Asia”.

“Their achievements with our QuestUAV DATAhawk, both in standard and PPK versions, are outstanding in terms of their quantifiable output following such high-profile flights as these. This mission is just one of their many achievements in China.

“Roctec have extracted the best of the stability of the aircraft, the exceptional quality of the SONY QX1 Camera and accuracy the Septentrio dual frequency AsteRx DGPS rover.

“The all weather capability of the system in sub zero, high altitude temperatures provided the final benefit for ROCtec to capture data for survey grade maps for mapping government construction.”

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 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.
