Why an autonomous vehicle needs combined navigation, not GPS + guesswork
Heading is where single-antenna GNSS fails — a stopped vehicle has no course-over-ground, and magnetometers lie next to steel chassis and drive motors. The GNS982's dual-antenna RTK arrangement measures true heading to 0.1° per metre of baseline, while its internal Kalman filter fuses gyroscope and accelerometer data to hold 0.15° attitude and 0.1 m/s velocity through a full 60 seconds of GNSS lockout.
