摘要：A method of compensating for GNSS (Global navigation satellite system)/RTK (Real-time kinematic) course angle data by way of electronic compass for unmanned system is proposed. The course angle jitter is found out. Since, GNSS/RTK receiver cannot offer stable heading data in specific conditions including but not limited to susceptible to obstacles, complex electromagnetic environment, and fewer satellites. The compensation algorism is based on the determination of GNSS course angle variance ratio and asynchronous characteristic between GNSS and electronic compass. The combined data provide accurate and robust navigation information to the outdoor unmanned system. A typical measurement is conducted which were then compared with the ordinary RTK navigation results that verified the potential of the proposed compensation method.
