The method of local area network timing based on BDS user terminal

Based on application requirements of Local Area Network (LAN) timing, a scheme is designed based on BeiDou Navigation Satellite System(BDS) user terminal. With developed software, the UTC time is imported from the user terminal to LAN as a local reference time source. Then the UTC time of local equipment are unified by a LAN timing software. The test results show that the UTC timing accuracy can reach 200 ms, and the network timing accuracy is better than 500 ms.
