Aeromao’s Mapping UAVs Get GNSS PPK Upgrade


Mississauga, Ontario-based drone company Aeromao Inc. has rolled out a global navigation satellite system (GNSS) post-processing kinematic (PPK) upgrade for its Aeromapper 300 and Aeromapper Talon unmanned aerial vehicles (UAVs).

Aeromao says the GNSS PPK, available as an optional upgrade, is a turnkey solution that allows users to achieve up to 3 cm mapping accuracy with no ground control points.

According to the company, a big difference between PPK and real-time kinematic (RTK) solutions is how corrections are applied: Often, says Aeromao, the results from PPK are better than those derived from RTK because the PPK solution does not rely on a link that may be subject to interference.

The upgrade, which is delivered already integrated into the UAV, includes step-by-step instructions on how to process the GPS information in order to have the data ready for imaging processing software such as Pix4Dmapper or Agisoft Photoscan.

Aeromao says the GPS post-processing takes typically 20-40 minutes, depending on the size of the area surveyed.
