Holybro H-RTK Unicore UM982 (Dual Antenna)

Holybro's UM982 Dual Antenna RTK GPS is capable of providing highly accurate position data and producing non-magnetometric moving baseline yaw determinations for autopilots using only one GPS module. Using this GPS as a yaw source eliminates magnetic interference as well as other sources of interference. Even if the GPS units do not receive RTCM data this function takes place. This RTK is based on the Unicore UM982 NMEA GNSS module and supports RTK position adjustment for centimeter accuracy, GPS/GLONASS, Beidou, Galileo and QZSS global positioning systems.

Note: Recommended to use the H-RTK F9P Base or F9P Helical as the base station. The setup in Mission Planner and QGroundControl is simple. MP and QGC currently cannot automatically configure the UM982 as a base station, additional manual setup is required.
