RTK & GNSS

Standard GPS puts you within a few metres. RTK puts you within a few centimetres — and that difference is what separates a drone that holds its line from one that drifts into a fence.

Our RTK range pairs a multi-band, multi-constellation receiver with the correction link you need to reach centimeter accuracy. Options include the Unicore UM980 and UM982 for full-constellation tracking with dual-antenna heading, and the u-blox ZED-F9P for the broadest software and community support.

Choose by role: [RTK modules](/collections/rtk-modules) to embed in your own board or product, and [GPS-IMU modules](/collections/gps-imu-ins) when position alone is not enough and you also need attitude.

Every module outputs standard NMEA 0183 and RTCM over UART or USB, accepts corrections from an NTRIP caster or a local base station, and works with ArduPilot, PX4 and ROS out of the box.
