H-RTK Unicore UM982 Dual Antenna Heading Drone Flight Controller 4.75V~5.25V
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.
This GPS is ideal for providing compass-less YAW information to autopilots (commonly called GPS Heading or Moving Baseline Yaw). It prevents magnetic interference from vehicle motors, electrical systems, and environmental sources like metallic structures that can cause incorrect yaw reports.
- Dual Antenna GNSS: Utilizes dual antennas for precise heading information and enhanced orientation accuracy
- High-Precision GNSS Receiver: Based on Unicore UM982 module with support for GPS, GLONASS, Galileo, BeiDou, and QZSS constellations
- RTK Positioning: Centimeter-level accuracy with RTK corrections, dual-frequency support (L1/L2) to mitigate multipath errors
- Versatile Applications: Functions as rover (receiver) or base (transmitter) in RTK setups
