Abstract

The invention relates to a Beidou-2 positioning, timing and time service terminal, which comprises a main antenna, an auxiliary antenna, a cable and a charger, and is characterized in that the main antenna is used for supporting signal capturing, tracking and joint positioning for five frequency points of a BD2 (Beidou-2) system, a GPS (Global Positioning System) and a GLONASS (Global Navigation Satellite System) and supporting functions of RDSS short message communication and active positioning of the BD2 system; the auxiliary antenna is used for supporting signal capturing, tracking and joint positioning for five frequency points of the BD2 system, the GPS and the GLONASS; the cable comprises a power supply cable and a data cable, the power supply cable mainly completes power supply of the main antenna for the auxiliary antenna, the data cable realizes wired-mode orientation through observed quantity data mutual transmission of the main antenna and the auxiliary antenna; and the charger completes offline charging for a battery of the main antenna and a battery of the auxiliary antenna. The main antenna and the auxiliary antenna of the Beidou-2 positioning, timing and time service terminal adopt an integrated design, functions of a data transmission station are integrated in the main antenna and the auxiliary antenna, and that is, the equipment can independently complete a pseudo-range differential positioning and realize a wireless orientation function between dual antennas at the same time.

Description

technical field [0001] The invention belongs to the field of satellite communication, and in particular relates to a Beidou-2 positioning, timing and timing terminal, an orientation method, a positioning method and a communication method. Background technique [0002] With the rapid development of the Beidou navigation industry, there are more and more navigation-related products on the market with more and more functions. At the same time, the market has put forward new functional requirements for Beidou positioning and orientation equipment, requiring the equipment to be able to complete positioning, orientation, timing and anti-jamming platforms, to achieve rapid and reliable navigation, positioning and orientation functions, to provide accurate timing services, and to have narrow-band Anti-interference ability. [0003] For products with differential positioning currently on the market, the differential information is transmitted in a wired manner, and auxiliary test eq...
