|Abstract:||The mode parameters for GPS common view time transfer is estimated and an unbiased weighting method (UBWA) for data in GPS common view is discussed in this paper, The one 5 jitter of each time series is determined by the standard deviation of residuals of polynomial regression, which define weights used to compute a weighted average. Averaging the double difference observables during an integral length (30 days), the systematic biases existing between every two time series are corrected in constant monthly relative to a reference time series. The GPS common view data among NRC in Ottawa, NBS in Boulder and USNO in Washington DC, are calculated by using three different methods: UBIWA, equal weights average method (EWA), and direct weighting method (DWA).|
