Problems solved by technology
[0003] The passive positioning, navigation, and timing services provided by the Beidou satellite navigation system adopt a working mechanism similar to that of GPS: conventional terminal receivers need to complete functions such as signal acquisition and tracking, demodulation and despreading, and data calculation. Slow, long time to first fix (TTFF, time-to-first-fix), unable to get positioning information indoors, only passively receive satellite information

Abstract
An auxiliary Beidou satellite positioning system comprises a BDS (Beidou satellite navigation system) satellite, a mobile communication network, an A-BDS (auxiliary BDS) location server, and an A-BDS terminal receiver. The A-BDS terminal receiver is communicated with the mobile communication network through a mobile network communication functional module and receives data from a BDS through a Beidou receiver. The A-BDS location server is provided with the mobile network communication functional module and is communicated with the mobile communication network through the mobile network communication functional module. A positioning tracking terminal based on the auxiliary Beidou satellite positioning system comprises a control module, a power module, a mobile network communication functional module, a Beidou receiver, a display module and a keyboard. The control module receives data from the Beidou receiver and controls operation of the Beidou receiver. The control module controls operation of the mobile network communication functional module, the display module and the power module.
Description
technical field [0001] The technical solution is based on an auxiliary Beidou Navigation Satellite System (A-BeiDou Navigation Satellite System, hereinafter referred to as A-BDS) and a positioning and tracking terminal based on the system. This technical solution integrates the Beidou and the mobile communication network, improves the positioning speed, improves the problem of not being able to know the location indoors, and solves the problem of data transmission. Background technique [0002] The Beidou Satellite Navigation System (BDS) is an independently developed and independently operated global satellite navigation system that China is implementing. It officially provided services to most of the Asia-Pacific region on December 27, 2012, and plans to complete the construction of the global system by 2020. . The Beidou satellite navigation system, together with the US Global Positioning System, the Russian GLONASS system and the EU Galileo positioning system, is a cert...
