About the new-generation Beidou satellite launched Vehicle Positioning/Car Tracking Mobile DVR System

   The Beidou Navigation Satellite system is a global navigation satellite system developed by China. It is the third mature satellite navigation system after THE GLOBAL Positioning System (GPS) of the United States and the Russian GLONASS satellite navigation system. Beidou Navigation Satellite System (BDS), GPS of the US, GLONASS of Russia and GALILEO of the EU are accredited suppliers of the UN Satellite Navigation Committee.

   Beidou satellite navigation system by air plane section, the ground and the user of three parts, can be all-weather and all day on a global scale for all kinds of users to provide high precision, high reliable positioning, navigation and timing services, and short message communication ability, has preliminary area navigation, positioning and timing ability, positioning accuracy of 10 meters, velocity accuracy of 0.2 m/s, The timing accuracy is 10 nanoseconds.

   The Beidou-3 basic system began global service on December 26, 2018. In September 2019, the BDS officially began global service. Among the 39 satellites in orbit, there are 21 Beidou-3 satellites: 18 in the middle circle orbit, one in the geostationary orbit, and two in the inclined geosynchronous orbit. The 47th and 48th Beidou navigation satellites were successfully launched on a Long March-3b carrier rocket from the Xichang Satellite Launch Center at 5:10 a.m. on September 23, 2019. On November 5, 2019 at 1 am 43 points, the successful launch beidou navigation satellite, 49 beidou system no. 3 last tilt (IGSO) geosynchronous orbit satellite launch completely, on December 16, with 22 points and 15 at the xichang satellite launch center to "an arrow binary" means the successful launch of 52, 53 beidou navigation satellite. So far, all the satellites in the middle earth orbit have been launched.

   China successfully launched the 54th navigation satellite of the Beidou System on a Long March-3B carrier rocket from the Xichang Satellite Launch Center at 19:55 on March 9, 2020.
