Embodiment 1

[0026] Embodiment 1: as Figure 1-3 As shown, a Beidou GPS dual-mode positioning method with the Beidou short message function, the Beidou short message module performs short message communication and the determination of Beidou positioning coordinates through the Beidou transceiver antenna, and obtains short message information and user coordinate information. Send the received short message information and user coordinate information to the ARM main control module; at the same time, the Beidou / GPS dual-mode module receives the Beidou satellite signal and GPS satellite signal through the Beidou / GPS antenna, and transmits the received Beidou satellite signal and GPS satellite signal The signal is transmitted to the ARM main control module, and then the ARM main control module combines the user coordinate information with the Beidou satellite signal and GPS satellite signal to obtain the user position coordinate information; the ARM main control module internally converts the sh...

Abstract

The invention relates to a Beidou-GPS dual-mode positioning method with a Beidou short message function and belongs to the field of communication and positioning. A Beidou short message module obtains short message information and user coordinate information, and transmits the short message information and the user coordinate information to an ARM master module. Further, a Beidou-GPS dual-mode module receives a Beidou satellite signal and a GPS satellite signal through a Beidou / GPS antenna and transmits the same to the ARM master module. The ARM master module then fuses the user coordinate information, the Beidou satellite signal, and the GPS satellite signal to obtain user position coordinate information, converts the short message information and the user position coordinate information into a digital signal, normalizes the digital signal, displays received information on an LED indicator light module and an RS-232 interface module, and transfers the received information to a computer. The Beidou short message module can communicate by using the Beidou short message function in certain emergency circumstances, and is obviously improved in positioning accuracy.

Description

technical field [0001] The invention relates to a Beidou GPS dual-mode positioning method with the Beidou short message function, belonging to the technical field of communication and positioning. Background technique [0002] With the continuous development of science and technology, at present, most of the Beidou / GPS dual-mode positioning systems researched and designed at home and abroad are used in the fields of daily vehicle positioning and transportation. Dual-mode navigation not only promotes the rapid development of my country's Beidou navigation system, It also combines the advantages of Beidou and GPS to make the positioning more accurate. However, most digital-analog systems use the combination of Beidou system and GPS, and the short message communication function is still insufficient. Especially in some cases where the mobile phone signal cannot be covered, the dual-mode system cannot communicate with the outside world in time. [0003] In order to solve the pro...
