Tiantong-1 01 satellite - China's own communication satellite, 100% independently developed, was successfully launched in August 2016.
Recently! China's independent "satellite phone" has officially launched, declaring that we have completely bid farewell to the era of relying on foreign satellites!
After nearly two years of efforts, China Telecom has launched its first satellite mobile communication system for the commercial market, marking China's entry into the "mobile phone era" of satellite mobile communication, filling the gap in domestic independent mobile communication systems, breaking the current situation of relying on foreign satellite mobile communication services, and having important milestone significance.
The ground service of Tiantong-1 is operated by China Telecom Corporation Limited and will form a mobile communication network together with the ground mobile communication system.
The launch of China Telecom Satellite Communication Branch and domestically produced full network+satellite mobile phone, this small and portable mobile phone with mobile satellite communication function, can be used to communicate with family and friends in real-time and without barriers even when traveling to the ends of the earth, completely breaking the monopoly of satellite phones by foreign countries.

Tiantong Smart Satellite Phone: I have a Chinese chip!
Looking back at Wenchuan in 2008, after the 8.0 magnitude earthquake, the ground communication network in the earthquake stricken area was completely paralyzed. At that time, China did not have its own mobile communication satellite system and could only purchase foreign satellite phones and rent foreign mobile communication satellite systems for earthquake relief.
Until August 2016, Tiantong-1 01 satellite was sent to the designated transfer orbit 36000 kilometers away from Earth by the Long March 3B carrier rocket. This is a high-capacity geosynchronous orbit mobile communication satellite developed by the Fifth Research Institute of China Aerospace Science and Technology Corporation, and also China's first mobile communication satellite, filling the gap in China's satellite mobile communication field and completely breaking through the barriers of foreign mobile satellite communication system monopolies!
After the successful launch of Tiantong-1 01 satellite, Tianhai World actively cooperated with China Telecom Satellite Communication Branch, which is responsible for the ground business operation of Tiantong-1, to promote market research and equipment development of Tiantong-1 terminal equipment. After continuous testing and improvement, the first smartphone capable of making satellite calls was launched.
This satellite phone integrates China's independently developed Tiantong-1 mobile satellite communication system chip, which is 100% Chinese chip. It can be used as a regular smartphone in urban public network environments. In areas where traditional ground mobile communication networks cannot cover or are unstable, satellite communication mode can be activated. It is not affected by the ground environment and can communicate with the outside world without barriers, making "not in the service area" a thing of the past, refusing to disconnect from the network, and never losing contact again!
The Tiantong-1 01 satellite and the ground mobile communication system together form a mobile communication network.
The first domestically produced full network+satellite phone is about to go on sale. With a satellite phone, even if you travel to the ends of the earth, you can use it to communicate with family and friends in real-time and without barriers.
The difference between satellite phones and ordinary smartphones is that ordinary smartphones display "no service" in areas that are not covered or unstable by traditional ground mobile communication networks, and the signal grid will display a "X"!
But with satellite phones, in areas where the ground mobile communication network cannot cover or is unstable, satellite communication mode can be activated, unaffected by the ground environment, allowing for seamless communication with the outside world no matter where you are, and never losing contact again!
What can Tiantong-1 achieve in the future?
In addition to emergency communication in the event of natural disasters, Tiantong-1 can also be widely used in various fields such as personal communication, ocean transportation, offshore fishing, aviation rescue, tourism and scientific research.
It can support confidential voice communication, data transmission and video conference, realize disaster rescue, maritime rescue and remote area rescue, carry out long-distance education, telemedicine, radio and live broadcast and other services, and provide high-end business users such as scientific research and exploration with Internet access, personal mobile communication and other services.
Tiantong-1 can also play a significant role in personal applications. In the near future, we can use Tiantong-1's high-speed data transmission service to conveniently conduct online work or chat with friends on WeChat while traveling long distances by plane.
For the Tiantong satellite phone tariff package, according to current information, the network access fee is 300 yuan/household, and real name registration is required! The monthly package is 100 yuan and includes 60 minutes of domestic calls; The annual package is 1000 yuan, which includes 720 minutes of domestic calls, with an excess of 1.6 yuan/minute and 0.4 yuan/text message.
Tiantong-1 working frequency band
The working frequency band of Tiantong-1 is S-band, with an uplink frequency range of 1980~2010MHz and a downlink frequency range of 2170~2200MHz.
At present, the communication capacity can meet the usage requirements of one million users. The service types of Tiantong-1 satellite phone include voice, short message, fax, data, video, etc. The service speed ranges from 1.2kbps to 384kbps, which is not yet comparable to 3G/4G.
Finally, everyone must be curious about the price of satellite phones. Here are the relevant prices······
Compared to the high cost of commercially available satellite phones, the retail price of domestically produced satellite phone phones will start from 10000 RMB, and communication costs will start from 1 RMB per minute, which is equivalent to 1/10 of that of international mobile satellite companies.
Compared to some hyped brands of mobile phones, the price of satellite phones is relatively reasonable, but it is not a price that the public can afford.
