Satellite navigation ground differential reference station and system thereof

Abstract

The invention discloses a satellite navigation ground differential reference station and a system thereof. The technical purposes of lowering the complexity of base station establishment and improving the processing capacity of a differential reference system are achieved. According to the satellite navigation ground differential reference station, a base station is connected with a remote data processing center through the Internet. The system is provided with a frequency mixer module, a network communication controller module, a high-accuracy difference data calculating module, a data storage module, a data distribution module and a user access module. Compared with the prior art, satellite negative signals are processed through a radio frequency collector and a data processing center instead of a base station, the complexity of base station construction is effectively lowered, station construction can be achieved in complex terrain environments, the signals are processed at the data processing center, observation data higher in accuracy and difference correction data are obtained with the help of the powerful calculation capacity of cloud, and therefore the satellite navigation ground differential reference station construction efficiency and the difference correction data processing efficiency are improved.

Description

technical field [0001] The invention relates to a satellite navigation positioning device and its system, in particular to a satellite navigation ground differential reference station and its system. Background technique [0002] The satellite navigation ground differential reference station is an important part of the high-precision satellite navigation positioning system. With the help of the high-precision differential correction data provided by the satellite navigation ground differential reference station, the real-time dynamic differential positioning method based on satellite navigation can obtain centimeter-level or even sub-centimeter level of positioning accuracy. The satellite navigation ground differential reference station in the prior art uses a fixed-position high-precision satellite navigation receiver as a reference station, obtains differential correction data through continuous tracking of satellite signals, and sends them to the rover to complete differe...
