Construction method and construction system of self-check system of satellite ground-based augmentation system

Abstract

The invention discloses a construction method and construction system of the self-check system of a satellite ground-based augmentation system. The method includes the following steps of: a data receiving and detection step: a reference station is adopted as a mobile station located in a grid, after observation data from the reference station are received, detection is performed, and the working status of the base station is reported; a strategy formulation step: a coverage strategy is formulated according to the working status of the base station; and a network differential verification step:network differential verification is performed according to the differential data of the satellite ground-based augmentation system itself, the data detected in the data receiving and detection step,and the coverage strategy formulated in the strategy formulation step, and self-check is performed on the satellite ground-based augmentation system. According to the construction method and construction system of the self-check system of the satellite ground-based augmentation system of the invention, the ground-based receiving station is adopted as the detection mobile station, and therefore, alarge-scale ground-based augmentation network can be effectively detected, and the service capability of the ground-based augmentation network can be improved.

Description

technical field [0001] The invention relates to the field of satellites, in particular to a construction method and system for a self-inspection system of a satellite ground-based augmentation system. Background technique [0002] With the development and popularization of satellite positioning technology, network communication technology and computer technology, precise location services have gradually penetrated into various industries, and the application of differential positioning technology based on ground-based augmentation systems is becoming more and more popular and urgent. Generally, precise location service providers need to establish a complete ground-based augmentation system to provide differential data processing and broadcast services. The ground-based augmentation system is a very important part of a complete precise location service. How to grasp the implementation, operation and service capabilities of the ground-based augmentation system is an urgent pro...
