Features
The Holybro UM982 Dual Antenna RTK GPS provides high-precision
positioning information and is capable of generating non-magnetometer
moving baseline yaw determinations for autopilots with one single GPS module.
One of the best applications of this GPS is to provide compass-less
YAW information to the autopilot (commonly called GPS Heading or
Moving Baseline Yaw). Using this GPS as a yaw source prevents
magnetic interference from the vehicle motors and electrical
systems and any environmental interference sources, such as
metallic structures or equipment, that can cause incorrect
yaw reports to the autopilot.
This works even if the GPSs are not receiving RTCM data from a
fixed RTK station or NTRIP server. The device is based on the
Unicore UM982 NMEA GNSS module and supports RTK positioning
adjustment for centimeter-level accuracy, GPS/GLONASS,Beidou,
Galileo, and QZSS global positioning systems.
It also includes a magnetometer, LED, and safety switch button.
It also serves as an RTK-corrected vehicle GPS, with or without
moving baseline yaw determination, and as a base station GPS for
sending RTCM data to a ground control station to provide an
RTK source for the vehicle via telemetry.
Features
•Dual antennas allow Moving Baseline Yaw (GPS Heading) with just one module
•Can replace the traditional compass/magnetometer
•Perfect for system/environment with high magnetic interference
•Excellent RTK performance
Tips: It is recommended to use the H-RTK F9P-Base orF9P
Helical as your base station because it's simple setup
procedure in Mission Planner & QGroundControl. Neither MP
nor QGC can configure the UM982 automatically as base
station at this moment, additional manual setup is required.
