摘　　要：为了验证多频GNSS跟踪站接收机观测数据的质量和相关性,为GNSS跟踪站接收机后续研制做出贡献。基于多品牌多频GNSS跟踪站接收机比测试验,评估了观测数据的伪距噪声,对伪距噪声序列、伪距零基线双差序列进行自相关分析,进而对P-L序列从时域和频域角度进行滤波周期分析,验证了多频GNSS跟踪站接收机观测数据的相关性。试验结果表明:多频GNSS跟踪站接收机观测噪声满足相应标准,不同品牌跟踪站接收机的伪距观测量具有不同程度的自相关性,为削弱观测数据的伪距噪声,不同品牌跟踪站接收机对伪距数据做了不同周期的Hatch滤波处理。In order to verify the quality and correlation of multi-frequency GNSS tracking station receiver observations and contribute to the subsequent development of GNSS tracking station receivers.In this paper,we evaluate the pseudo-range noise of the multi-frequency GNSS tracking station receivers,carry out autocorrelation analysis on the pseudo-range noise sequence and the pseudo-range zero baseline double difference sequence,and then carry out filtering cycle analysis on the P-L sequence in the time and frequency domains to verify the correlation of the multi-frequency GNSS tracking station receiver observation data.The experimental results show that the observation noise of the multi-frequency GNSS tracking station receiver meets the corresponding standard,and the pseudorange observations of different brands of tracking station receivers have different degrees of autocorrelation.
