H-RTK Unicore UM982 (Dual Antenna Heading)The Holybro UM982 Dual Antenna RTK GPS provides high precision positioning information and is capable of generating non magnetometer moving baseline yaw determinations for controllers with a single GPS module. One of the best applications of this GPS is to provide compass less YAW information to the controller (commonly called GPS Heading or Moving Baseline Yaw). Using this GPS as a yaw source prevents magnetic interference from the vehicle motors and
