The Chinese official released the white paper "China Beidou Satellite Navigation System" for the first time, and proposed the goal of the Beidou system: China's Beidou, the world's Beidou. The "contention" between the Beidou system and the US Global Positioning System (GPS) has drawn attention.
Where is the "contention"?
According to the white paper, the Beidou system will complete 35 satellite launch networks around 2020 to serve global users.
At present, Beidou system has been able to provide services to more than 30 countries and regions. The service area of ​​the running Beidou No. 2 system is 55 degrees north-south and 55 degrees east to 180 degrees east, and the positioning accuracy is better than 10 meters. In low-latitude areas such as Thailand, the positioning accuracy is better than 5 meters.
"This precision is comparable to the performance of civil signals such as GPS in the United States and Glonas in Russia." Cheng Chengqi, director of the China Satellite Navigation System Management Office, told the China News Service that the positioning accuracy is expected to double by the completion of the global network. Up to 2.5 meters".
Shen Jun, deputy director of the International Cooperation Center of China Satellite Navigation System Management Office, said in an exclusive interview with China News Service that Beidou and other satellite navigation systems must have a competitive relationship in terms of frequency, track, intellectual property and market share.
To this end, in accordance with the "open, transparent" development principles, China has timely released relevant documents such as system interface control documents and public service performance specifications, and domestic and foreign manufacturers can develop Beidou equipment accordingly. In key service areas such as Russia, Pakistan, and Thailand, China seeks a win-win situation through joint ventures and cooperative projects. In particular, the United Nations satellite navigation regional training center was established to train satellite navigation talents for foreign users.
"åˆåˆ" is the general trend
More people realize that "there must be a long time."
For example, in some application areas, relying on a single system cannot guarantee availability, and achieving interoperability between Global Navigation Satellite Systems (GNSS) will improve availability and reliability. "It turns out that the Beidou/GPS-compatible receiver can significantly improve the performance of the device without significantly increasing the cost." Shen Jun said that, for example, Samsung's Note3 and subsequent products have the function of receiving the Beidou signal.
In response to his introduction, China is promoting the international development of the Beidou system from four aspects: first, actively participate in the activities of international organizations such as the United Nations Global Navigation Satellite System Committee; secondly, carry out inter-system cooperation with countries such as the United States, Russia, and Europe. Negotiations have completed the first round of frequency coordination; third, continue to promote Beidou into international organizations such as international maritime affairs, international civil aviation, global mobile communications and general data standards; fourth, actively promote overseas applications, and have been with Pakistan, ASEAN, the Arab League and other countries. Cooperation with the region.
The reporter learned that Beijing Hezhong Sizhuang Technology Co., Ltd., as a technology provider, independently developed and built the Pakistan National Location Service Network (Phase I) project. This is Beidou's first overseas commercial project, providing centimeter-level real-time positioning services for Karachi, Pakistan's largest city.
Shen Jun said that the system has been widely used for two years. At present, China and Pakistan are discussing and developing Phase II projects for the China-Pakistan Economic Corridor and follow-up projects covering the whole of Pakistan.
"complement" Qi short board
In the opinion of experts, whether it is "competition" or "combination", the most important thing is "hard work and short-board".
Yang Qianli, chairman of the China Satellite Application Conference, believes that the premise of the marketization of the Beidou system is “good quality and low priceâ€, and this is still a technical problem that needs to be overcome.
Hu Gang, president of the Big Dipper Company, also told the China News Agency that there are two outstanding problems in the Beidou industry: on the one hand, there is a gap between product quality and application performance in special scenarios and international products; on the other hand, lack of chips and terminals The innovation, the homogenization of many enterprises is serious.
Qi Chengqi also has the same view. "In the case of Beidou chip companies, there are hundreds of them." He said that the government will guide and encourage enterprises to merge and reorganize. Enterprises should also recognize the consequences of homogenization competition and actively "carry the group" to enhance international competitiveness.
Not long ago, the National IC Industry Investment Fund announced that it would support the Beidou industry for the first time. According to Beidouxingtong, which is funded, the funds are mainly used for the development of Beidou chips, cloud-based positioning enhancement and auxiliary platform system development.
"The white paper released this time represents the country's commitment to the world: providing reliable and secure satellite navigation services. This will further enhance users' confidence in using Beidou." Hu Gang said that the company will refine itself according to the overall development strategy of Beidou system. Planning, especially for the “Belt and Road†region to open up the market, “Beidou industry is bound to usher in a new phaseâ€.
