Internet of Things and BDS Application

Internet of Things and BDS Application by Bo Wang, Xiangsheng Liu, and Yaqi Zhang

Preface to Internet of Things and BDS Application PDF

With the continuous development of the new generation of information technology, the combination of the Internet of things (IoT), which provides perceptual information, and the satellite navigation system, which is the spatiotemporal benchmark, is becoming closer and closer.

As China’s independent and controllable spatiotemporal benchmark, Beidou satellite navigation system (BDS) provides complete global services from 2020.

The key of technology lies in the application. The close combination of precise spatiotemporal information with the interconnection of all things not only empowers a variety of industries, but also leads the reform of more industries.

According to the statistics of GNSS and LBS Association of China (GLAC), the total output value of Chinese satellite navigation and location-based services industry has exceeded 400 billion Yuan in 2020, of which BDS has contributed more than 80% to the core output value of the industry.

Therefore, the continuous development of IoT and BDS application is not only related to the national security of China, but also greatly promotes economic development of China.

With the development of 5G, cloud computing, big data, artificial intelligence, and a series of emerging technologies, the IoT and BDS application will bring more vigorous vitality to the development of the industry.

BDS is a global satellite navigation system built and operated independently by China and compatible with other satellite navigation systems in the world.

Since the 1990s, China has completed the construction of BDS-1, BDS-2, and BDS-3 systems in accordance with the “three-step” strategy, “First active and then passive, first regional and then global,” and has blazed a road of satellite navigation system construction with Chinese characteristics.

Guided by the BDS spirit of “Independent innovation, unity and cooperation, overcoming difficulties and pursuing excellence,” BDS system provides global service capability through high-density networking, ensures stable service with high operation speed, creates new highlights of international cooperation with high standards, and drives new breakthroughs in application with high precision.

The BDS system has reached the level of 10 m at 95% confidence level, the positioning accuracy of 10 m height, the speed of 0.2 m/s, the timing accuracy of 20 ns, and the availability of system services more than 95%. In the Asia-Pacific region, the positioning accuracy of 5 m is achieved at 95% confidence level. People all over the world can enjoy the service of BDS system.

Through the BDS ground-based augmentation system, the precision of the spatiotemporal information provided by BDS can be improved to the centimeter level of real time and millimeter level of post-processing.

The accurate spatiotemporal information can be widely used in various industries with extremely low cost and convenient way.
