rtk base station positioning test system and method

Abstract

The invention provides a RTK base station positioning test system and a method thereof. The method comprises: a full-band GNSS antenna firstly receives GNSS carrier phase signals of different frequency bands, and transmits the GNSS carrier phase signals to a full-system full-band GNSS receiver; the full-system full-band GNSS receiver receives and decodes the GNSS carrier phase signals, and sends the decoded GNSS carrier phase signals to a processor; the processor receives the decoded GNSS carrier phase signals, encodes the decoded GNSS carrier phase signals according to the user configuration,and sends the decoded GNSS carrier phase signals to a transmitting server; and finally, the transmitting server receives and transmits the mobile GNSS receiver of the mobile end of the encoded GNSS carrier phase signals. The method may meet the receiving requirements of different RTK mobile terminals in the test field, and the test is accurate, convenient, time-saving and labor-saving, which improves the working reliability and stability of the base station.

Description

Technical field [0001] The present invention relates to the technical field of communication processing, in particular to an RTK base station positioning test system and method. Background technique [0002] In the current automatic driving positioning, the high-precision differential positioning system based on RTK (Real-time kinematic) carrier phase differential technology can provide positioning accuracy within 10 cm, which is suitable for the positioning needs of automatic driving. RTK technology has Become an indispensable positioning module in autonomous driving. [0003] RTK technology is essentially a high-precision GNSS (Global Navigation Satellite System, Global Navigation Satellite System) differential technology. The ordinary GNSS system can reach a dynamic accuracy of 10 meters through pseudorange calculations. DGNSS (Differential Global Navigation Satellite System, The differential global navigation satellite system) technology can eliminate multipath effects and cer...

Problems solved by technology

At this time, in order to test in the autonomous driving test field, the autonomous driving research company needs to configure the RTK base station paired with its mobile GNSS receiver by itself, which will bring many problems. On the one hand, the self-configured base station needs to be manually input In the process of base station configuration, the installation position of the antenna will inevitably be offset, which will bring about a few centimeters of absolute position error of the base station, thus increasing the error of the RTK hardware system

On the other hand, if the communication device and communication interface of the test site are used when configuring the base station, different unmanned vehicles may use RTK hardware systems designed by different companies and different communication protocols, and too many third-party applications will be used. base station, resulting in the occupation and waste of resources

In addition, it takes time and effort to configure the base station, and hardware installation and power supply need to be taken into account, which reduces the reliability and stability of the base station.
