Compatible with Raspberry Pi series boards, Jetson Nano
& high update rate
used as either reference station, or positioning terminal
By setting up continuous running reference stations on ground known fixed coordinates using the ZED-F9P module, or by paid RTK base station enhanced services, transmitting GNSS observed value to ZED-F9P terminals which uploading rough positioning data, the terminals, with errors like multipath refraction, is able to calculate observed value in real time, for centimeter level positioning in seconds.
Moving base RTK (MB RTK) is a function that concurrently uses two or three ZED-F9P modules to output precise deflection angle, altitude, centimeter level positioning coordinate, or attitude angle. It is suitable for applications like vessel heading determination, heavy machinery moving control, agriculture vehicle heading control, and so on.
