Follow on Google News | Why is China's beidou terminal so expensive?Why China's Beidou-1 navigation terminal price is hight? the point is that it is using expensive imported Chips. However, China has found replacement.
By: jointthinking The main reason why it is not popular as expected is that Beidou-1 terminal is far more expensive than US's GPS terminal. Its price is about 20,000 CNY, while normal GPS only costs several thousand CNY. I have been curious about why its price is so high. As Qi Faren (Chinese Academy of Engineering) Today I learn that in February 2008, a chip called "Pilotage No. 1" has been developed by a company in Shanghai. The chip is fully demestically- Hope that it is true. How Beidou-1 works, the following procedure is utilized: 1. A signal is transmitted skyward by a remote terminal. 2. Each of the geostationary satellites receive the signal. 3. Each satellite sends the accurate time of when each received the signal to a ground station. 4. The ground station calculates the longitude and latitude of the remote terminal, and determines the altitude from a relief map. 5. The ground station sends the remote terminal's 3D position to the satellites. 6. The satellites broadcast the calculated position to the remote terminal. # # # About: China defense, military, blog articles, I will try to give my ideas and points of view. Could you please leave some comments if you have any opinion or thought? End
