H-RTK Unicore UM982 (Dual Antenna Heading)

Navigation & GNSS
by Holybro

Description

The Holybro Unicore UM982 is a high-precision dual antenna RTK GPS receiver that provides centimeter-level positioning accuracy and moving baseline yaw determination. It features dual antennas for GPS heading without requiring a magnetometer, making it ideal for environments with magnetic interference. The device supports multiple GNSS constellations including GPS, GLONASS, BeiDou, Galileo, and QZSS, with RTK horizontal accuracy of 0.8cm + 1ppm and vertical accuracy of 1.5cm + 1ppm. It can operate as a rover, moving baseline rover, or base station, and includes a built-in IST8310 compass, LED indicators, and safety switch.
