Abstract:

The ultra-tight SINS/GNSS coupled technology is a hotspot and difficulty of navigation research, because of its important theoretical significance and application value, which is studied widely in domestic and abroad. Due to the different intentions and purposes, ultra-tight methods proposed by researchers are different in principle and structure, even there is not a unified classification. The research status of ultra-tight SINS/GNSS integrated technology is reviewed and the principle is analyzed in detail. The advantages and disadvantages of all the ultra-tight methods are analyzed and summarized. Based on that,ultra-tight methods are divided into correlator data loosely fusion, deeply fusion and pseudo range data fusion. Finally, the development trends of the ultra-tight technology are pointed out.
