Scope

Scope: This standard specifies the conditions, equipment, procedures, and data processing for the single-point positioning accuracy test of satellite navigation receivers. This standard applies to the field test of the single-point positioning accuracy of satellite navigation receivers (hereinafter referred to as "receivers"). Main technical content: 3.1 Satellite navigation receivers (GNSS receivers) are devices that receive satellite navigation signals by measuring code phase, carrier phase, and navigation messages, or devices that have the former function and can receive and process satellite navigation ground enhancement system (NBAS) data products broadcasted via satellite, mobile communication networks, digital broadcasting, etc. to achieve high-precision navigation and positioning. 3.2 Single-point positioning (SPP) is a basic service provided by satellite navigation, which uses the pseudo-range observations and broadcast ephemeris of satellite navigation receivers to achieve positioning. 3.3 The National BeiDou Augmentation System (NBAS) mainly consists of reference stations, communication network systems, data processing centers, data broadcasting systems, user terminals, etc. It is a system that broadcasts augmentation signals to improve the accuracy and integrity of satellite navigation positioning. 3.4 Reference stations set up satellite navigation measurement-type receivers and communication terminals at control points, continuously observe and receive satellite signals within a certain period of time, and transmit the data to the national data integration processing system of the satellite navigation ground enhancement system, which processes and broadcasts differential correction data. They are also known as reference stations. Reference stations are an important component of the satellite navigation ground enhancement system. 4.
