摘要
陕西天文台 (CSAO)的多通道GPS/GLONASS接收机 (R1 0 0 /3 0T)自 2 0 0 1年6月起处于试运行阶段 ,经过系统调整和反复调试 ,两套接收机从 8月 8日以来取得正常接收结果。对两套接收机作了零基线共视比对 ,单通道GPS的单个记录的比对精度达± 1 .79ns;在同一时间多通道GPS比对平均值的精度达± 0 .82ns。GLONASSP码单通道的单个记录比对精度达± 0 .82ns ,多通道平均值的精度达± 0 .57ns。上述精度与国际上同类型接收机相比较说明 ,CSAO的这两套R1 0 0 /3 0T的质量较好 (噪声小 )。CRL和CSAO的R1 0 0 /3 0T数据的共视比对结果说明 ,把多通道GPS/GLONASS接收机用于远距离时间比对 (尚未进行精密星历表改正 ) ,精度可以达到± 4.79ns (GPSC/A码 )和± 2 .2 7ns (GLONASSP码 )。
Two multi channel GPS/GLONASS R100/30T receivers started to be in test running at the end of June 2001 and the significant results for time transfer have been calculated for 4 months.The common view time comparison with both zero baseline and long baseline are shown as test data reductions.The results show much better precision and stability with multi channel GPS C/A code observations (GPS C/A MC) than with single channel ones and it is of excellence with GLONASS P code observations (GLONASS P).The standard deviations (RMS) reach ±1.79ns and ±0.57ns for GPS C/A MC and GLONASS P respectively with zero baseline,and the RMSs reach±4.79ns and±2.27ns respectively for the long baseline of CSAO CRL.
