  Both Tiantong and Beidou satellites are part of China's homegrown satellite systems。The Tiantong satellite is mainly used for communication, while the Beidou satellite is mainly used for navigation and positioning。

  Tiantong Satellite: Communication。

  The Tiantong satellite system is China's first self-developed mobile communication satellite system, which is mainly used to provide voice, SMS and data communication services。

  Coverage:The Tiantong satellite system consists of three geosynchronous orbit satellites, covering the entire territory of China and surrounding areas。This means that whether it is in the vast sea or deep in the mountains, as long as there is a signal from the Tiantong satellite, it can communicate。

  Communication function:The Tiantong satellite not only supports voice calls, but also sends and receives text messages and data communications。In contrast, terrestrial communication networks are often unable to cover remote areas, while Tiantong satellites can provide all-weather, all-region communication services。

  Application scenario:The satellites are widely used in emergency rescue, Marine fisheries, forest fire prevention and other fields。

  Beidou Satellite:Navigation + Positioning

  The Beidou Satellite System is China's self-developed global satellite navigation system, which is mainly used to provide positioning, navigation and timing services。

  Global coverage:The Beidou Satellite System consists of 55 satellites and covers the whole world。Whether in bustling cities or remote villages, Beidou satellites can provide accurate positioning services。

  Navigation function:Beidou satellites can not only provide high-precision positioning services, but also carry out short message communication。This means that in places where there is no signal, it can also send location information through Beidou satellites to ensure safety。

  Application scenario:Beidou satellites are widely used in transportation, agriculture, fisheries, forestry and other fields。

  The main challenges Tiantong satellite faces in communication technology are signal coverage and transmission stability。Beidou satellites need to solve the problem of high-precision positioning and global coverage。Both have their own technical merits, but both represent China's leading level in the field of satellite technology。

  Although Tiantong and Beidou satellites are different in functions and applications, they together form an important part of China's autonomous satellite system。Tiantong satellites are mainly used for communication, while Beidou satellites are mainly used for navigation and positioning。Whether in emergency rescue, or in daily life, these two satellite systems play an important role。
