China Satellite Navigation Systems Management Office

International civil terminal developers to come up with a real product for at least another year. Domestic early development of the vendors will be qualified in advance to launch its own terminal. Recently, the State Council Information Office held his first news conference of the Beidou satellite navigation system. Beidou satellite navigation system spokesman, Ran Chengqi Xuan cloth Management Office of China's satellite navigation system, the Beidou satellite navigation system from today, to China and the surrounding areas to provide continuous navigation and positioning and timing services. The end of next year, the Beidou system was basically completed, will provide official to run the service, when the positioning accuracy of the coverage area of 10 m.

Beidou satellite navigation system has launched 10 satellites, and built a basic system. Retain the Beidou satellite navigation experimental system active positioning and short message communication services to China and the surrounding areas to provide continuous navigation and positioning and timing services. However, currently available civilian Beidou navigation terminal, the vast majority of car navigation systems, is to use the U.S. GPS signals for navigation. In 2005, the Chinese Academy of Engineering, Qi Faren, once said that, the Beidou system would have the ability of millions of users, but only a few thousand users. The state has invested billions of dollars, each year there are a lot of depreciation charges, but underutilized, resulting in a waste of resources. 2010, in which case there is not much improvement, the number of users are still tens of thousands.

To take full advantage of the Big Dipper lies with the development of civilian terminal. Ran Cheng said at a news conference, the Beidou system to provide commissioning services related to domestic enterprises have begun to proceed with the Compass application terminal of the R & D R & D as well as the Big Dipper and GPS compatible terminal. New financial reporter learned that the National Proton Electronic Technology Co., Ltd., located in Chengdu at the end of last year on the development of successful Beidou navigation terminal of the RF chip and baseband chip. The use of the RF chip, the analog signal to accept the days of satellite launch, zoom, and into a digital signal. The baseband chip the role is to select the satellite in the sky, and select a certain algorithm to decode the satellite model, in order to read out the location and time information.

Big Dipper, vice president of segment Zhao Yu had said Choi new interview, the cost of a terminal is still relatively high, because chip production to reach 100,000 can do a cost of about $ 300,400. In today's conference, much concern Beidou satellite navigation system satellite navigation industry at home and abroad signal in space interface control document (ICD) beta officially released. The file specification of the Beidou satellite navigation system and the user receiving terminal of the signal interface between the technical documentation of the necessary development and manufacturing of the receiving terminal and the chip.

Prior to this, only a handful of mazda dvd player domestic companies signed an agreement with the Management Office of China's satellite navigation system, this paper, conditions for early development. The ICD file after the announcement, the global navigation terminal developers can choose the load Beidou signals acceptance in their own products. Chen Xin, deputy general manager of Topcon company told financial reporters, With this file, generally six months they can come up with engineering prototype, at least another year to come up with real products. Domestic early development of the vendors will be qualified in advance to launch its own terminal.
