Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] The GPS and Beidou positioning switching system provided by the present invention includes a GPS receiver, a Beidou receiver, a switching control module, an interface conversion module and a power supply module, realizes simultaneous positioning of GPS and Beidou on ships, and selectively outputs GPS as required Or Beidou positioning data.

[0023] The GPS receiver and Beidou receiver work normally under the power-on state, output the positioning data of the RS232C interface and send it to the switching control module, and the switching control module selects to output GPS or Beidou positioning data according to the status of the GPS / Beidou switching switch on the device panel, The interface conversion module converts the positioning data into RS422A interface or network interface data, and outputs it to other devices through the aviation plug on th...

Abstract

The invention discloses a GPS and Beidou positioning switching system. The GPS and Beidou positioning switching system comprises a GPS receiving machine, a Beidou receiving machine, a switching control module, a port switching module and a power supply module. The GPS receiving machine, the Beidou receiving machine and the port switching module are connected to the switching control module via an RS232C port. The GPS receiving machine receives satellite signals from a GPS antenna, carries out resolving and positioning so as to obtain GPS positioning data, and outputs the GPS positioning data to the switching control module via the RS232C port. The Beidou receiving machine receives satellite signals from a Beidou antenna, carries out resolving and positioning so as to obtain Beidou positioning data, and outputs the Beidou positioning data to the switching control module via the RS232C port. The switching control module receives mode control instructions and switching control instructions input by the exterior. The mode control instructions comprise a manual control instruction and an automatic control instruction. The switching control instructions comprise a GPS switching instruction and a Beidou switching instruction. The switching system is capable of selectively outputting GPS or Beidou positioning data as required.

Description

technical field [0001] The invention belongs to the technical field of ship positioning, and in particular relates to a GPS and Beidou positioning switching system. Background technique [0002] GPS (Global Positioning System) global positioning system is currently the most widely used navigation and positioning system in the world. Its positioning accuracy is high. Using differential technology, the positioning error can be controlled within the range of meters; the coverage is wide, and at least 4 satellites can be observed all over the world. Satellite; the technology is mature, and various receivers have been developed and produced to meet different needs. [0003] Most ships in our country are equipped with GPS receivers to locate the ship in real time. However, the GPS satellites and ground monitoring stations are controlled by the United States. If it injects interference strategies into the satellites, the positioning of the ships will no longer be accurate, which w...
