THE CHOICE OF PROFESSIONALS

“We conducted a ground-based site surveying by qualified surveyors with survey grade total stations to evaluate the accuracy of the KlauPPK system. Then with a Klau calibrated X4s camera on a DJI Inspire2 drone we captured aerial data at a 10mm ground sampling distance. The Klau Geomatics post processing software geo-tagged the images in our… Read more “”

“The KlauPPK application is awesome, its’ performance far better than I would have anticipated, and something I’ve been looking for since 1993. Great technical support from Klau team is second-to-none especially in adding support to our custom Geoid models and fulfilling our survey requirements.”  

“The accuracy we are now able to achieve with UAV surveying is truly remarkable, thanks to KLAU PPK’s revolutionary technology. With KLAU PPK’s system, Stahly Engineering consistently receives results accurate to 3 cm (XYZ) or better on our wide array of projects. Our ability to provide our clients with cost-efficient, high-quality UAV products has drastically… Read more “”

“Videographics Ingenieurgesellschaft is an engineering company, providing technical demanding drone services in Germany and a KLAU PPK reseller. We have been able to impressively demonstrate 2 cm accuracies in all axis repeatedly, without the use of GCPs for both interested customers who are dying to get a GCP-free solution and our tech service customers.” “Technically… Read more “”

“The experts at Klau Geomatics have really revolutionized precision drone data collection with their PPK unit. The system allows us to outfit our existing equipment with accurate camera positioning.” “I’ve been working for couple of years with the Klau Geomatics team and they have been awesome.”

After conducting numerous missions of trial areas, as well as comparisons to physical GPS/laser scanning surveys I have observed the following accuracies : Camera accuracy MAX 30mm (as reported in agisoft)
PPK accuracy AVG 12mm (compared to RTK points)
GCP accuracy AVG 4cm (compared to RTK points, flown at GSD 3.2, 120m AGL)Read more “”

“The accuracy of the Klau PPK Module exceeds expectations every time. I have performed some checks using a surveyor’s Total Station against the results from the Klau PPK Module, and if the flight is done at low altitude and with a large overlap, the accuracy on any point is as good as single measurement performed… Read more “”

“Our UAV is now my main piece of survey equipment on the mine site. We’re getting productivity and accuracy like never before. I have found them to be extremely helpful in getting us up to speed even with photogrammmetry processing workflow and providing very useful tips and tricks. I would highly recommended this PPK solution… Read more “”

“Basically this PPK unit is awesome.
Most errors come in at around 20mm horizontally and 30mm vertically. The worst result I have achieved is 49mm vertically on a checkpoint, and 33mm horizontally. This is well within spec for the work we do with the UAV.” “I read numerous articles on PPK vs RTK, and… Read more “”
