Beidou system needs to launch more than 30 satellites in order to complete the network, which makes space experts from the beginning of the mission to realize that the localization of the system for the construction and stable operation of life and death, can not be stuck by others "life gate." In the Beidou development Process, the key components of the foreign manufacturers have suddenly notified due to government cessation of supply events .At this time domestic technology research has been completed, the experts decisively decided to use domestic substitute .Foreign learned that post-pause, not only immediately Supply and cut prices by more than half.But, China has tasted the sweetness of the core technology, which further strengthened the determination of BeiDou localization.
It is worth mentioning that the Beidou 3 using China's first self-developed anti-radiation quad-core SoC2012 chip system, as well as China's own intellectual property calculator operating system SpaceOS2. Experts said the performance of the chip is Compass Phase I Compared with the operating systems such as Windows, iOS and other operating systems, SpaceOS2 is not only smaller in size, but also manages hundreds of tasks at the same time. In the satellite Operating more than 10 years, the operating system will not strike, slow.
According to reports, after more than 10 years of arduous efforts by space experts, long-term reliance on imports of traveling wave tube amplifier components, microwave switches, high-power power controllers and other key aerospace products for the first time to achieve the main and backup all localization, Compass 100% Parts localization.
