GPS (Global Positioning System) mobile base station rapid positioning and resolving method

Abstract

The invention provides a GPS (Global Positioning System) mobile base station rapid positioning and resolving method. A wireless communication network and a data transfer server are used for being coupled with a mobile base station and a GPS receiver in a flow base station, a corresponding coordinate system is built, further rapid positioning on the mobile base station is realized, the mobile base station and the flow base station are connected in a data transfer manner, and the mobile base station can move freely, thus coverage area of the mobile base station can be effectively adjusted. Besides, the GPS mobile base station rapid positioning and resolving method provided by the invention can effectively avoid a barrier between the mobile base station and the flow base station, a communication link between the mobile base station and the flow base station is ensured to be smooth, and efficiency for positioning the mobile base station is improved.

Description

technical field [0001] The invention relates to a GPS positioning method, and specifically designs a method for fast GPS positioning by using a wireless communication network. Background technique [0002] High-precision GPS measurement must use carrier phase observations. RTK positioning technology is a real-time dynamic positioning technology based on carrier phase observations. It can provide real-time three-dimensional positioning results of the station in the specified coordinate system, and achieve centimeter-level accuracy. In the RTK operation mode, a fixed base station and a user rover station are required. During operation, the base station sends its observation information to the rover station through the data link. The mobile station not only receives the data from the base station through the data link, but also collects the original GPS observation data through the antenna. The random software of the mobile station performs real-time processing on the double-di...

Problems solved by technology

[0003] The emergence of this technology has greatly expanded the use space of GPS, making GPS positioning technology widely used in geodetic surveying and other industries related to location information, but the conventional GPS differential technology has obvious shortcomings: 1. As the distance between the rover and the reference station increases, the correlation of spatial correlation errors (tropospheric delay, ionospheric delay, ephemeris error, etc.) Implement RTK operations within a distance of 15km near the reference station; 2. The communication link is not smooth, and it is difficult to successfully send differential information to the long-distance mobile station by using the low-power radio station of the reference station. These limitations have seriously affected its scope of use
