Freefly RTK GPS Ground Station

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

The Freefly RTK GPS Ground Station provides real-time GNSS correction to achieve centimeter-level positional accuracy for Astro drone operations. By acting as a fixed RTK reference, the module connects to a ground station computer and transmits live correction data to an RTK-equipped Astro aircraft.

Built around the u-blox ZED-F9P multiband receiver, the system enhances both horizontal and vertical accuracy beyond standard GPS capabilities. It is intended for professional operators who require precise, repeatable positioning for demanding aerial missions.

Key features and technical benefits

• Real Time Kinematic correction enables centimeter-level positioning accuracy.
• u-blox ZED-F9P GNSS module supports multiband L1 and L2 signals.
• Ground station sends live correction data to Astro RTK rover.
• Multiband antenna supports stable satellite signal reception.
• Magnetic mount fits standard 1/4-20 tripod interfaces.
• Integrated sensors provide operational awareness and safety feedback.
• USB connection links ground station to control computer.
• Designed and assembled in USA for professional operations.

Reliable RTK reference performance for Astro workflows

RTK positioning relies on a stable reference station paired with an airborne rover to improve GNSS precision. The Freefly RTK GPS Ground Station serves as that reference, mounting securely to a tripod and interfacing with a ground station computer via USB.

During operations, it delivers correction data in real time, reducing positional drift and improving flight accuracy. This capability supports Astro missions that depend on consistent, high-confidence positioning.
