'The Beidou map is not equivalent to the Beidou satellite. Any company can do something called the Beidou Map App.' Xu Ying expressed her opinion on a question and answer platform. She emphasized that the Beidou system and the Beidou map are not directly linked. The satellite system is unable to make maps. Gaode, Baidu and other map software can also use Beidou satellite navigation.
Beijing Science and Technology News reporter tried to contact the Chongqing Beidou Seven Star Internet Technology Co., Ltd., a research and development company of the Beidou map. A person in charge of answering the phone indicated that it was not clear about the launch of the Beidou map, and provided the reporter with a link from the “Relevant Business Department”. 2. After the reporter tried to dial several times, the phone never answered.
According to Dr. Wang Dacheng, a senior expert of 3S applications, the head of the Department of Remote Sensing and Digital Earth Research of the Chinese Academy of Sciences, Dr. Wang Dacheng stated that 'Beidou Navigation' and 'Beidou Satellite Civilian' are two different application areas. Some news reports are suspected of exaggerating facts. He emphasized that although the BeiDou Satellite has technically adopted the civil conditions, it is subject to various reasons. Currently, due to the fact that the networking has not been fully successful, it is still more military and industrial applications. If one day is really a large-scale specialization The accurate source of information for use should be a similar authority such as the National Bureau of Science and Technology for Defence. As for the company's “Beidouxingxing” company, Wang Dacheng said that he had not heard of it.
In fact, as a self-developed satellite navigation system in China, from 1994 to the present, Beidou navigation has already gone through 24 years and has been very low-key. In 2012, the Beidou II system successfully launched the 16th satellite. After the start of the system, the system will be officially opened and the service area will cover the Asia Pacific region. Currently, Beidou positioning has entered the third phase and has launched 29 satellites in total. It is estimated that the launch of 35 satellites will be completed around 2020, serving Asian-based global users. .
Wang Dacheng introduced that there are currently four major global navigation satellite systems in the world, including the United States GPS (Global Positioning System), Russia GLONASS (Glonas), China's BDS (Beidou), and the EU's Galileo system (Galileo). From technology From the above perspective, the Beidou navigation system is very advanced. GPS can be completed. The Beidou system can also be completed. GPS cannot be completed. The Beidou system can do the same. However, the maturity of technology does not mean that the application is universal. Compared with the system, there is still room for improvement.
