Abstract

The invention discloses a method for realizing Beidou / GPS (Beidou / Global Positioning System) integrated navigation under a Windows CE (Embedded Compact) system. Based on a universal embedded Beidou satellite navigation and positioning system platform, the system platform comprises a processor module, an input / output module, a navigation and positioning communication module and a display module, wherein the processor module is a hardware core module of the system, the navigation and positioning communication module is an integrated navigation module consisting of a GPS navigation module and a COMPASS module, and the integrated navigation module is mounted on a mobile terminal; after positioning request information is sent by the mobile terminal, analysis, resolving and synthesizing of positioning data information are respectively carried out by the GPS navigation module and the COMPASS module, and navigation parameters after the resolving of respective subsystem are output; finally, the optimal estimated values of the navigation parameters are output by an integrated navigation filter. Through the adoption of the technology, the navigation and positioning precision, reliability and redundancy of a satellite navigation system in a mobile terminal field can be further improved, so that the navigation and positioning effects are superior to those of ordinary single navigation systems.

Description

technical field [0001] The present invention specifically relates to a method for realizing Beidou / GPS combined navigation under the Windows CE system, which is mainly used in the field of vehicle navigation or mobile terminal navigation. It adopts the Beidou 2nd generation and American GPS combined navigation method, and makes the two kinds of navigation The method combines advanced filtering algorithm to realize high-precision and high-reliability navigation and positioning. technical background [0002] At present, in the field of domestic navigation products, the application of Beidou navigation products has just started in recent years. The construction of my country's Beidou satellite navigation system has now entered the second stage, and its services have covered most of China and the Asia-Pacific region. The construction of the third phase of Beidou will be completed in 2020. Judging from the actual situation of the second generation of Beidou, because there are fe...
