The satellite navigation system will no longer be just the GPS

Fascination with UAVs, concerned about the radiation computer, robot nanny interested in ... for the people of Chongqing, the fair is a technology feast.

Yesterday the opening of the fair site, each high-tech products in front of a crowd of fans crowd side to side relish to comment.

Beidou satellite is far away from us  Nearly two to three hundred kilometers away tens of thousands of kilometers. In fact, the Beidou satellite very close from us, you have been able to use it for car navigation. Yesterday, the China Aerospace Science and Technology Corporation, deputy general manager Zhang Jianheng Industry Development Summit Forum in the military and civilian integration revealed that the Beidou satellite system in the first half of this year, will cover the Asia-Pacific region, we drove to travel navigation Beidou satellite system in 5-8 years, global coverage.

The Beidou satellite navigation system developed its own satellite positioning and communication system (CNSS), in addition to mature third after the United States Global Positioning System (GPS), the Russian GLONASS satellite navigation system.

Public can use the Beidou satellite system for their own driving directions. "Said Zhang Jianheng There are many research institutes and enterprises during the Beidou-based application development, Beidou Navigation System, or Beidou GPS dual system, China now part of the safety of transport vehicles have been loaded onto the Beidou navigation system.

The Zhang Jianheng introduction, has now been launch 13 Beidou satellite, covering the Asia-Pacific region in the first half of this year, the original plan in 2020 to achieve global coverage, will launch 40 Beidou satellite. Now they are studied and the civil aviation system, the Beidou system applied to international flights.

In addition to the the Beidou vehicle positioning and navigation system, the Chinese Academy of Sciences, Chongqing Green Smart Technology Research Institute shows the handheld Beidou terminals for outdoor workers, ALICE navigation guiding, you can also send satellite SMS.

"Beidou GPS compared to two different, send text messages and timing." Hospital the Beidou engineering director of the Center RESISTANCE WAR AGAINST introduced, the GPS can navigate, but can not communicate when there is no cell phone signal, you can not keep in touch with the outside world, but the Big Dipper Send SMS function, an accident in the wild, you can send satellite text messaging to communicate with the outside world.

This handheld beidou terminal much thicker than the phone now, above, in addition to the display, below navigation, alarm, digital keys. Can still enter text and mobile phones to send text messages, in case of emergency situations by the alarm button, the control center will receive the alarm. RESISTANCE WAR AGAINST said the price of such a device is 1 million, and any satellite phone to send text messages, and is free of charge.

The Beidou system timing function is based on accurate clock in the satellite down to a broadcast transmission, the timing accuracy of 50 nanoseconds (a nanosecond is one billionth of a second). Main products: car DVD player and car dvd , are with good quality.  According to reports, has been the Big Dipper watch, but more expensive, will seek to mass production in 2-3 years, and the general public can also be used to the timing can be precisely locate the Big Dipper watch.
