BDS is an important state space infrastructure. Since its completion in 2018, the BDS preliminary system has been working continuously in a stable condition. Currently, BDS has entered the era of global services. With its application industries emerging rapidly, BDS becomes a striking “State Namecard”. 


The BDS system development inherits the features of its previous generations, matches the world-class standards. The BDS-3 Preliminary System is completed to provide global services with positioning accuracy better than 10 meters. In the future, new services such as satellite-based augmentation, short message communication, international search and rescue, and precise positioning will be provided, and better navigation signals will be broadcast. At the same time, the BDS-2 system, which has been operating steadily for six years, has been steadily improved in its performance. Four backup satellites have been launched. The system is more stable and the positioning accuracy in the Asia-Pacific region remains at the level of 5 meters. In addition, the construction of the BDS Ground-based Augmentation System results in nation-wide network, which can provide real-time centimeter-level high-precision services. An International GNSS Monitoring and Assessment System is completed, which possesses the capability to monitor and assess the four major satellite navigation systems, including BDS. 


From the aspect of application industry, a complete industrial chain has been formed. The standardized use of BDS in national security and key areas and the large-scale BDS applications in the mass consumption market are accelerating the emergence of a new mode of "BeiDou+" integrated applications. In 2018, China's domestic navigation industry output value has exceeded 300 billion yuan. At present, the technological craftsmanship level of the domestically produced BDS chips has stepped into a new era of 28 nanometres. For the Internet of Things and consumer electronics applications, the chips which comprehensively adopting the new BDS-3 signal system have been introduced. The chip overall performance has reached or even surpassed that of similar products in the world. Domestic BDS chips have achieved large-scale applications, with a total sales of more than 80 million pieces. High-precision OEM boards and receiver antennas have been accounted for 30% and 90% of the domestic market, respectively. The BDS high precision products have been exported to more than 100 countries and regions, and the BDS Ground-based Augementation technologies and products are exported overseas systematically. 


From the aspect of the international cooperation and exchanges, BDS has stepped out of the country and is speeding up its entry into the world. Establishing the China-Russia Satellite Navigation Major Strategic Cooperation Project Committee and the China-US Satellite Navigation Cooperation Machanism, signing the China-Russia Intergovernmental Cooperation Agreement on Satellite Navigation, and signing the Joint Statement on System Compatibility and Interoperability with the United States and Russia respectively, are accelerating the win-win development of multi-systems, ensuring better services for global users, providing China's programs and making China's contribution. China has been actively participating the work of the United Nations International Committee on Global Satellite Navigation Systems (ICG). After hosting the Seventh Meeting in Beijing in 2012, the thirteenth Meeting was held in Xi'an in 2018 to promote the vigorous development of global navigation satellite systems. We will continue to promote international BDS standards, actively participate in the drafting and revision of international standards for civil aviation, maritime affairs and mobile communications, and make important progress in the relevant work of the International Search and Rescue Satellite Organization and the International Electrotechnical Federation (IEC). China accelerates the process of global BDS applications, establishes cooperation mechanisms with more than 30 countries and international organizations, constructs the first BeiDou/GNSS Center in Tunisia, successfully holds the Second China-Arab State BeiDou Cooperation Forum, and steadily promotes the BDS services, products and enterprises to the Arab countries. 


By the end of 2019, six to eight more satellites will be launched to enhance system performance continuously; and in 2020, BDS will be fully developed as one of the world’s first-class satellite navigation systems to provide better services. By 2035, with BDS as the core, a more comprehensive, more integrated and intelligent national integrated positioning, navigation and time (PNT) system will be completed.  


“A top-class BDS is made in China, but for the whole world”. With a new attitude, stronger function and better performance, BDS will serve the world and benefit the mankind.
