Abstract

The invention provides GNSS monitoring equipment. The GNSS monitoring equipment comprises a signal monitoring host and a GNSS antenna. The signal monitoring host is internally provided with a GNSS board card, an MCU processing module and a display module. The GNSS board card is connected with the GNSS antenna. The MCU processing module is respectively connected with the GNSS board card and the display module. The invention further provides a monitoring point data quality analysis method. The monitoring point data quality analysis method comprises the steps of installing the equipment, collecting data, calculating a position precision attenuation factor qualification rate, a multipath error qualification rate, a cycle slip-free rate, an epoch effective rate and a satellite cut-off elevationangle effective rate of a monitoring point through using the MCU processing module in the GNSS equipment, configuring different weights for all indexes according to the environment of the monitoringpoint, and acquiring final comprehensive indexes and site selection suggestions of the monitoring point. The GNSS monitoring equipment disclosed by the invention is convenient to carry, and gives suggestions for establishing monitoring points by calculating each index.

Description

technical field [0001] The invention relates to the technical field of GNSS monitoring, in particular to a GNSS monitoring device and a monitoring point data quality analysis method. Background technique [0002] Global Navigation Satellite System (GNSS) is a space-based radio navigation and positioning system that can provide users with all-weather three-dimensional coordinates, speed and time information at any point on the earth's surface or near-Earth space, including China's Beidou satellite navigation Global Positioning System (GPS) in the United States, GLONASS in Russia and GALILEO in the European Union. With the successful construction of my country's Beidou satellite navigation system, GNSS positioning technology has also been widely used in various fields that rely on positioning technology. Monitoring and other aspects have been widely used. [0003] Since the satellite is in outer space far away from the ground, the signal transmission to the ground receiver wi...
