At present there are 4 navigation systems in the world. These are China’s Beidou; the EU's Galileo system, which China has participated in, and that will be deployed in 2013; Russia's GLONASS system completed in 2010; and the United States’ GPS which currently has the monopoly of the navigation market.
China wants a place in the area of global satellite navigation. However, to achieve this, our Beidou navigation satellite system will require independent research and vigorous development. This will allow it to become an application for our satellite navigation systems in the cause of national security. The application will also benefit the construction and development of our economy, and help in various areas of people’s daily life and more.
Navigation, positioning and timing data available within satellite navigation systems can play an important role in the development of transportation, finance and communications, as well as helping to provide efficient, stable and safe operations of electric power systems. Therefore, as finance and power are lifelines of national economic construction and development, and need to keep pace with the times, the earlier the application of the Beidou the better.
Highly featured in the Beidou system is its domestic atomic clock’s stability. With daily changes of only 1/1000000000 of one second, it can play a vital role in the synchronization of electric power network time through the collection of highly accurate time and frequency data.
This paper introduces the composition of the Beidou satellite navigation system as well as the principle of its work. It analyses and compares the different characteristics of the Beidou against the GPS, GLONASS and Galileo systems. The paper also discusses the application of the Beidou satellite navigation system in the field of finance and power and puts forward some valuable suggestions in overcoming its problems and shortcomings.
