Abstract

The invention discloses a high-precision position-independent GNSS monitoring virtual reference method, which comprises the following steps: S1, obtaining the position information of the area to be monitored or the monitoring station, and obtaining its coordinates; S2, sending the above-mentioned coordinate information to the enhanced position Server; S3, the enhanced location server generates a virtual reference station according to the received information, keeps the position of the virtual reference station unchanged, and obtains the virtual observation value of the virtual reference station; S4, uses the virtual reference station as a monitoring reference station, and communicates with each GNSS The monitoring stations perform differential positioning calculations to obtain the coordinates of each monitoring station relative to the position reference of the virtual reference station. The invention greatly improves the monitoring service area of ​​a single GNSS reference station, and can avoid wrong monitoring results finally obtained due to the displacement of the reference station in traditional GNSS monitoring. Compared with the method, the method has better stability.

Description

technical field [0001] The invention relates to the field of GNSS monitoring, in particular to a high-precision position-independent GNSS monitoring virtual reference method. Background technique [0002] Global Navigation Satellite System (GNSS) is the collective name for various satellite navigation and positioning systems in the world. Several major positioning and navigation systems currently in operation include the GPS system of the United States, the GLONASS system of Russia, the Galileo system of the European Union, and the Beidou satellite navigation system of my country. GPS. GNSS positioning technology has attracted widespread attention due to its all-weather, global coverage and high-precision positioning, and has been widely used in surveying and mapping, aerospace, land transportation, exploration, timing, marine and military industries. [0003] The content of GNSS monitoring mainly includes horizontal displacement, vertical displacement and offset distance, t...
