Chinese Academy of Sciences: Map of the Beidou System, the map is good or bad depending on other factors

According to reports previously, the Beidou Map APP is expected to go live on May 1. Its navigation function can be accurately within 1 meter, and it can clearly locate specific lanes. Xu Ying, a researcher of the Institute of Optoelectronics at the Chinese Academy of Sciences, made a comment on this matter. .

First of all, the Beidou system is a satellite navigation and positioning system. It is a type of GPS system, GLONASS system and Galileo system. It is responsible for providing location information, mainly referring to longitude, latitude, and altitude information. Google and Gaode maps are mapping software. It mainly provides location-based value-added services, using remote sensing satellites, map observation vehicles, drone observations, etc. to display locations, plan routes, provide congestion, etc. Both are not at all a level.

Second, the BeiDou system is not likely to make maps. The BeiDou system can provide very accurate location information for certain calibration points in the map, but it cannot make a map. From now on, the BeiDou Map APP and the BeiDou satellite Navigation system has no direct relationship.

Finally, whether or not the BeiDou system can be used depends on which satellite navigation system is used for positioning. Ultimately, it depends on the hardware of the mobile phone. If your mobile phone does not have the hardware to support the BeiDou system, then it is useless to download which APP. , The buddies still check the parameters of their own mobile phones to see if they support the BeiDou system.
