Freefly RTK GPS Ground Station

Freefly RTK GPS Ground Station: centimeter-level RTK accuracy for Astro Max

The Freefly RTK GPS Ground Station enables centimeter-level horizontal and vertical positioning accuracy for professional Astro drone operations. Using Real Time Kinematic technology, this ground-based module allows a connected ground station computer to transmit live GNSS correction data to an RTK-equipped Astro aircraft.

Built around the u-blox ZED-F9P multiband receiver, the system improves positional accuracy from meters to centimeters in real time. This solution is intended for operators who require precise navigation, repeatable positioning, and reliable GNSS performance for accuracy-critical missions.
