Simplification Techniques for Common-View Time Transfer System Based on the EURO-160 GPS Receiver

GPS common-view is the main method for the time and frequency remote transfer originally, of which the uncertainty can reach several nanoseconds. This paper presents a procedure to simplify the original common-view time transfer system constructed using a powerful dual-frequency multi-channel EURO-160 GPS receiver and a high precision time interval counter SR-620. The relevant data-processing software is designed according to "Technical directives for standardization of GPS time receiver software". A preliminary zero-baseline experiment shows that the new system can reach almost the same accuracy as that ensured by the original system. The structure of the new system is simple, practical and reliable, the simplification techniques for common-view transfer system can provide better services and more choices for the time and frequency remote transfer.
