Abstract: Although satellite positioning technology greatly facilitates people's travel, there are also many abnormalities in practical applications, such as insufficient accuracy and weak signals. This paper designs a Beidou GPS SINS integrated positioning system based on embedded operating system. The system integrates Beidou and GPS satellite information, and uses SINS to make up for the lack of GPS and Beidou in weak signal areas. Through testing, this article concludes that the B2A signal is relatively stable and can provide good signal services for the entire system. The PDOP value of the Beidou system in the study area ranges from 1.0 to 1.7 (average value is 1.280), of which the basic distribution range in our country is 1.1 to 1.2 (average value is 1.163), indicating that the positioning accuracy in the horizontal direction is better than that in the vertical direction; the tdop value ranges from 0.621 to 0.856-0.8 (average 0.6423).

Keywords: embedded operating system; Beidou satellite; global positioning system; multi-system integrated positioning service.
