Test experiment s3129a. Observing stations: Mg, Ws Nominal start time: 2023.05.09_21:05:00 Nominal stop time: 2023.05.09_21:17:42 Start: 2023.129_21:05:00 End: 2023.129_21:17:42 Stations: mg,ws # Needed for CDDIS software Goal: To test errors of group delay determination. Bands b, c, and d are set to the same frequencies. I will compare group delays in bands b, c, d and assess an excess of differences with respect to the expected differences if they are entirely due to the thermal noise.
