A satellite timing service scene recording device and method based on a satellite timing module

Abstract

The invention discloses a satellite timing scene recording device and method based on a satellite timing module. The device includes a satellite timing module, a satellite timing scene recording module and a satellite synchronous clock control module. The satellite timing module receives navigation messages sent by a satellite simulator And analyze it to get the time information, and send the time information to the satellite timing scene recording module in the form of second pulse and serial port message; the satellite timing scene recording module receives the second pulse and time message information sent by the satellite timing module, and uses the received Based on the pulse per second, record and store the time message information and its receiving time, and based on the received pulse per second, send the time message information to the satellite synchronous clock control module according to the sequence of recorded time. The invention records and stores the output message of the satellite timing module, and resends the second pulse and the stored message according to the original time sequence when the output of the satellite timing module for simulating the scene is needed.

Description

technical field [0001] The invention relates to the technical field of GPS / Beidou satellite synchronous clocks, in particular to a satellite timing scene recording device and method based on a satellite timing module, an ARM chip and a FLASH chip. Background technique [0002] At present, during the development and debugging of GPS / Beidou satellite synchronous clock devices, the testing of some special scenarios, such as the time of leap second occurrence and errors in satellite navigation messages, can only be realized by using expensive satellite simulators. Satellite simulators are expensive, and ordinary companies cannot afford them. They can only entrust a third-party unit to test, which still requires a certain amount of money and is not convenient enough. [0003] How to record the satellite timing scene in the special scene simulated by the satellite simulator and get rid of the shackles of the satellite simulator is still a technical problem to be solved.
