| description | Disclosed are a system and a method for detecting a spurious signal in a global navigation satellite system (GNSS) receiver, which have improved performance. The detection of the GNSS receiver determines a first sequence of a known bit or a known bit transition of a spacecraft (SV) signal of a target SV. A second sequence is determined based on a consistent sum of SV signals tracked by the GNSS receiver. A first reliability sequence may be associated with the first sequence, and a second reliability sequence may be associated with the second sequence. Correlation statistics of the first sequence are determined on the basis of the second sequence. Whether the first SV signal is a spurious signal is determined based on comparison between the correlation statistics and a threshold value.
위성 항법 시스템(GNSS) 수신기에서 스퓨리어스 신호를 검출하기 위한 시스템 및 방법이 개시된다. GNSS 수신기의 감지는 대상 SV의 우주선(SV) 신호의 알려진 비트 또는 알려진 비트 천이의 제1 시퀀스를 결정한다. 제2 시퀀스는 GNSS 수신기에 의해 추적되는 SV 신호의 일관된 합을 기반으로 결정된다. 제1 신뢰도 시퀀스는 제1 시퀀스와 연관될 수 있고, 제2 신뢰도 시퀀스는 제2 시퀀스와 연관될 수 있다. 제1 시퀀스의 상관 통계는 제2 시퀀스에 기초하여 결정된다. 제1 SV 신호가 스퓨리어스 신호인지 여부는 상관 통계량과 임계값과의 비교에 기초하여 판단한다. |
