Research on Multi - channel GPS Common - View Method Time & Frequency Transfer Receiver

Common - view method of satellites of the GPS is international prevalent technology for time frequency transfer between remote clocks on the earch. Its kernel is the receiver of common - view method. The system of multi - channel GPS common - view method time frequency transfer receiver is researched successfully. The handware is composed of high precision time interval counter and VP ONCORE engine made in Motorola company. The software is accord with standardization guide for data process software of GPS common-view method. Compared with single channel receiver, it has not only friendly interface and convenient operation but also has the strong ability of analyse and process data. After experimented, the time transfer uncertainty of multi - channel GPS receiver is less than 4 ns( elevation is more than 40 degree) in the condition of the comparision of common - view and common - clock on zero base line.
