Abstract

The invention relates to the field of outdoor sports products, and discloses a fast timing watch based on the Beidou No. 3 system. Through the creation of the present invention, a new type of satellite watch based on the Beidou No. 3 system is provided to solve the problem of slow satellite timing, that is, on the one hand, by providing independent power supply for the RTC power supply in the satellite module, after the watch is reset or switched on and off, The ephemeris and other information inside the module and obtained from the last positioning are saved, so that the positioning or timing will be performed later, and the calculation speed of satellite signals will be greatly accelerated; on the other hand, through the B-CNAV1 of a single satellite The hour, minute, and second information of the current time can be obtained by calculating the second count within an hour, the hour count within a week, and the entire week count in the navigation message, so that the time service can be completed quickly and the user experience can be improved.

Description

Technical field [0001] The present invention belongs to the field of outdoor sports products, and specifically, a quick timing watch based on Beidou No.3 system. Background technique [0002] With November 19, 2018, China was successfully launched in Xichang Satellite Launch Center to successfully launch the forty-second, forty-three Beidou navigation satellites (these two satellites are the 18th system of China. The nineteen sets of network satellite) marks the successful completion of the basic system space constellation of the Global Network of Beidou No.3, China. At the national new office press conference held on December 27, 2018, the Director of the China Satellite Navigation System Management Office, Beidou Satellite Navigation System Spokesperson announced that "Beidou No. 3 basic system completed construction, starting to provide global services today ". [0003] The new generation of Beidou No. 3 has added multiple MEO satellites, increasing the coverage of the Beidou ...
