Drones2GNSS takes this year’s GSA Special Prize
This year’s winning project, Drones2GNSS, combines two of today’s hottest topics in global navigation satellite systems (GNSS): Galileo and unmanned aerial vehicles (UAVs). The project proposes an innovative approach to addressing a timeless problem of surveying engineers: positioning accuracy in urban canyons and vegetated areas.
“Although Galileo Initial Services are expected to enhance the accuracy of existing solutions, Drones2GNSS proposes an off-the shelf application that uses European GNSS (i.e., Galileo, EGNOS) as the primary means of positioning,” says project partner Space Geomatica’s Achilles Tripolitsiotis. “As GNSS signals are degraded in obstructed environments by skyscrapers, vegetation and geomorphology, our project proposes using drones as intermediate carriers of high precision GNSS signals that can then transfer the geolocation accuracy to the ground.”
