Abstract

The invention relates to a method for testing a multi-array-element RTK receiver in a complex interference environment and belongs to the technical field of satellite navigation. During testing, a base station receiver is tested firstly and then a mobile station receiver is tested; during testing of the base station receiver, a serial data synchronous acquisition and playback module synchronouslyacquires RTCM original observation data of the RTK receiver; during testing of the mobile station receiver, the serial data synchronous acquisition and playback module synchronously playbacks the acquired RTCM original observation data of the base station receiver to the mobile station receiver for the mobile station receiver to complete RTK high-precision positioning solution. The method has thebeneficial effects as follows: the mobile station and base station receivers receive the same satellite signals and same interference simultaneously, so that anti-interference performance test data ofthe base station and the mobile station are tested separately in the complex electromagnetic environment, and 100% available high-precision navigation can be continuously provided in an interferenceenvironment and the like.

Description

technical field [0001] The invention relates to a multi-element RTK receiver testing method in a complex interference environment, belonging to the technical field of satellite navigation. Background technique [0002] At present, RTK high-precision satellite navigation can achieve centimeter-level or even higher navigation and positioning performance by using roadbed enhanced auxiliary signals. With the prosperity of market demand, the application of high-precision satellite navigation is becoming more and more extensive. However, RTK high-precision satellite navigation is very fragile. It cannot continue to provide 100% available high-precision navigation in complex environments such as urban canyons where signals are completely blocked or interfered. Sudden radio interference can instantly deteriorate high-precision positioning results. to meter level. [0003] With the development of Beidou navigation anti-jamming technology, the current RTK receiver has a certain anti...
