Background

The GNSS is called a Global Navigation Satellite System (Global Navigation Satellite System), which generally refers to all Global Satellite Navigation systems and regional and augmentation systems, and performs Navigation and positioning using one or more Satellite Navigation systems including GPS in the united states, GLONASS in russia, GALILEO in europe, beidou Satellite Navigation System (BDS) in china, WAAS in the united states, EGNOS in europe (european geostationary Navigation overlay System), MSAS in japan, and the like, and simultaneously provides Integrity Checking information (Integrity Checking) of satellites and sufficient Navigation safety warning information.

The basic principles of GNSS: the distance between the satellite with known position and the user receiver is measured, and then the specific position of the receiver can be known by integrating the data of a plurality of satellites. To achieve this, the position of the satellite can be found in the satellite ephemeris from the time recorded by the on-board clock. The distance from the user to the satellite is obtained by recording the time that the satellite signal travels to the user and multiplying the time by the speed of light (because of the interference of the atmospheric ionosphere, the distance is not the real distance between the user and the satellite, but is the pseudo-range (PR). when the GPS satellite works normally, the GPS satellite continuously transmits navigation messages by using pseudo-random codes (pseudo-codes for short) consisting of 1 and 0 binary code groups.

However, the existing displacement device for GNSS measurement is complex in structure, generally has a single-movement displacement device or a three-dimensional displacement control device without a guide rail, is small in adjustable range, can only be applied to concrete ground, and does not have a guide rail to simulate a slope; some can only measure the precision of plane displacement, and some can only measure the precision in the vertical direction; some devices are complex and have large volume.
