Image: Drotek
Drotek Electronics is now offering the F9P Sirius RTK GNSS Rover, which is designed to be mounted on a moving vehicle. The u-blox ZED-F9P module inside provides 1-cm position accuracy, a convergence time under 10 seconds and a navigation update rate up to 20 Hz.
The new Sirius RTK GNSS Rover F9P has a built-in active antenna patch. It receives GPS, Galileo, Beidou and GLONASS signals, providing additional accuracy. The F9 Sirius Rover is designed to fit most setup designs as well as integrate easily into a vehicle. Its six-pin JST-GH connector makes it plug-and-play with the Pixhawk Pro 3 autopilot.
