Embodiment Construction

[0014] When tracking and locating high-speed moving targets, it is often necessary to use network assistance. The already obtained list of visible stars, orbital parameters of satellites, satellite clock corrections, predicted Doppler and code phase of satellites are directly transmitted to the GPS receiver carried by the target, and fast positioning can be realized.

[0015] Mobile phone, academically reasonable name should be called cellular mobile phone. It consists of a base station of a cellular mobile network, a mobile communication network connected to the base station, and a mobile phone (i.e. a mobile phone that is often called). When a mobile phone is in the service area of ​​a certain base station (such as figure 1Middle base station 1), the mobile phone is put on record at this base station. When the mobile phone is moving, when it transfers to another base station service area, during this process, several base stations near the mobile phone are measuring the f...

Abstract

The invention relates to an auxiliary global positioning system (GPS), which comprises base stations, a mobile communication network, a monitoring center and client terminal equipment; the client terminal equipment comprises a GPS and a mobile phone; a server of the monitoring center is provided with switching software; the mobile communication network is respectively connected with all base stations and the monitoring center through a wireless communication network; and the client terminal equipment is also connected with all base stations through the wireless communication network. Strict tracking, positioning and monitoring on a serviced vehicle can be realized under any condition by a double-positioning mode, and the monitoring center can give a satisfactory reply to a client whenever the client checks the condition of the vehicle so as to improve the service quality and the service level better. In the whole system, hardware equipment is not required, the positioning of location based service (LBS) can be automatically realized by switching software as long as the GPS is blocked only by depending on the function of the added switching software, the replace function of the original equipment is fully developed, and the performance of the positioning system is effectively improved.

Description

technical field [0001] The invention relates to a GPS positioning system, in particular to a dual positioning system for auxiliary positioning. To ensure that the managed vehicles are tracked, positioned and monitored throughout the day. Background technique [0002] The GPS system can realize all-weather and all-day continuous tracking, positioning and measurement targets. Has become an application technology. The GPS receiver is regarded as a discrete-time position and velocity sensor, which can provide the user with three-dimensional parameters of velocity and position. Since cesium or neodymium atomic clocks are installed on the GPS satellites, standard time parameters can also be provided, which can provide 7 usage parameters to users. Most of its users are based on land, and its applications range from personal location tracking of the elderly and children to remote management of various transport vehicles; from atmospheric physics observations to guiding the blind ...
