Abstract:

Common-View GPS has proven to be an accurate and reliable time transfer method capable of producing estimates of clock differences with a precision of 2-3 nanoseconds with averaging. The advent of multichannel timing receivers promises enhanced coverage and increased precision due to the large number of common-view passes available between any two sites. This paper discusses the processing techniques used to reap the benefits of the multi-channel receivers, and compares common-view results with those achieved using standard single-channel receivers. The precision of multi-channel common-view is shown to be less than a nanosecond with averaging over one day for a 2400-km baseline.
