Abstract: For the problem of insufficient anti-jamming capability of GNSS and INS cumulative error in autonomous driving scene of mine truck, this paper proposes a combined navigation algorithm based on GNSS and INS. This algorithm combines the advantages of the two algorithms to improve positioning precision and reliability. This article compares the RTK algorithm and the integrated navigation algorithm with the NovAtel onboard output and the open source software RTKLIB results. The results show that the accuracy of the algorithm in this paper is close to that of NovAtel's onboard output, and is better than the open source software RTKLIB. The average plane and elevation error and STD in this paper are better than 5 cm, and the average attitude error and STD are better than 1°, which can meet the positioning accuracy requirements of autonomous mining trucks.

Key words: mine truck, autonomous driving, GNSS, RTK, INS, integrated navigation
