Evaluation of Beidou Satellite Navigation Service Anti-jamming Capability Under International Standard Framework

Abstract

Anti-jamming capability is an important index of satellite navigation service. The anti-jamming capability is standardized in relevant standard documents such as International Civil Aviation Organization (ICAO), Radio Technical Commission for Aeronautics (RTCA), Aeronautical Radio, Incorporated (ARINC) and American Federal Aviation Administration (FAA). According to the basic framework of the international standard mentioned above, this paper carries out test and test on the anti-jamming ability of Beidou B1C signal, and carries out the baseline test on the pseudo-range tracking accuracy of the receiver of Beidou B1C signal in the aviation electromagnetic environment, and obtains relevant test data. On standardized test framework, Beidou B1C signal in limited bandwidth white noise interference tolerance, continuous wave interference tolerance and tolerance of the pulse interference and so on various types of interference tolerance under receiver capture signal carrier to noise ratio remained above 31 dB-Hz, the tracking error is lower than 0.5 m (1 sigma) of support the Beidou draft standards and recommended measures to develop and validate, which laid a foundation for the Beidou satellite navigation system to join the international standard system.KeywordsAnti-jamming capabilityBeidou satellite navigation serviceICAORadio technical commission for aeronautical
