On June 23, the BeiDou 3 global satellite navigation system constellation deployment was completed half a year ahead of schedule, which means that China's self-developed BeiDou system has completed the global network deployment.
Undoubtedly, this will further drive the layout of the whole industry chain of "BeiDou +", and the application will also be deepened and expanded.
By 2019, the total output value of China's satellite navigation and location services industry will reach 345 billion yuan, an increase of 3.5 billion yuan over 2018. 14.4%, in which BeiDou's contribution to the core output value is more than 80%.
According to expert analysis, China BeiDou system industry chain has basically realized independent research and development, especially in the upstream components and other key technology areas have made breakthroughs, product advantages are gradually emerging, involving BeiDou navigation positioning chip, antenna, RF chip and clock chip.
Recently, Zhejiang Saisi Electronics Technology Co., Ltd. has developed a clock synchronization SoC chip based on high-precision phase-locked ring technology to support BeiDou system, but there was no such commercial chip in China before.
BeiDou satellite timing system is good, can achieve a single star stable timing, to ensure that the entire timing application does not require satellite switching, to ensure timing stability and reliability, compared to GPS satellite switching will affect the timing accuracy is more promising.
Saisi's high-precision positioning timing service and functional technology can provide guarantee for time synchronization equipment, which will be widely used in 5G, smart grid, rail transportation, finance and other fields in the future.
