| Abstract: | It has been discussed this paper that the testing and calibrating means on precise time and frequency for the user terminals of COMPASS / GNSS navigation system, based on Virtual Instrument technology, on network technology and on batch measurement technology. It is put forward that the testing method based on modulization and on VXI / PXI / LXI bus technology, with the consistency design of standard time and frequency reference signals and the design of remote testing and calibrating based on network technology. At the same time, it is proposed that the structure design and it’s application of COMPASS / GNSS precise time and frequency testing and calibrating system. This way can upgrade the measuring level of COMPASS / GNSS time and frequency terminals with integration and intelligence. |
