How do you make and receive satellite calls? Tiantong-1 satellite comes to your rescue

Tiantong satellite phone can be used as a common smart phone or a satellite communication system. It is not affected by natural disasters and is online 24/7. Rescue workers can achieve zero-barrier communication through Tiantong satellite phone. So what is a satellite phone? Why can satellite phones communicate without signals? Today we will learn about the relevant knowledge about satellite phones.

The Tiantong-1 satellite mobile communication system is a satellite mobile communication system independently developed and constructed by my country, consisting of a space segment, a ground segment and user terminals.

Tiantong-1 satellite is developed by China Academy of Space Technology and together with the ground mobile communication system, it forms a space-ground integrated mobile communication network, providing users in China and its surrounding areas, the Middle East, Africa and other related regions, as well as most of the Pacific and Indian Oceans with all-weather, all-day, stable and reliable mobile communication services such as voice, short messages and data.

What is a satellite phone?

A satellite phone is a communication device based on satellite communication technology. It uses satellite networks deployed on the earth to achieve long-distance communication. Unlike traditional mobile phone networks that rely on ground base stations, satellite phones communicate directly with ground stations via satellites, thereby providing communication services when there is no ground communication infrastructure or when the communication infrastructure is damaged. Satellite phones send signals to communication satellites, which then forward them to other places. This method enables satellite phones to achieve global coverage. No matter where they are on the earth, as long as they can receive satellite signals, they can communicate.

The mainstream satellite phone services on the market include Skycom, Maritime, Shulaya and Iridium .

The origin of Tiantong-1 satellite

For a country like my country with a vast territory, uneven population distribution and frequent natural disasters, the development of satellite mobile communications is unstoppable. The 2008 Wenchuan earthquake paralyzed all ground communication systems in the disaster area, and the earthquake relief site could only rely on renting foreign satellite phone links to maintain communication with the outside world. After the Wenchuan earthquake, in order to have an independent mobile communication satellite system, my country launched the development of the Tiantong-1 satellite.

The project was officially launched in 2011. At 0:22 on August 6, 2016, China successfully launched Tiantong-1-01 using the Long March 3B carrier rocket at the Xichang Satellite Launch Center. This is the first satellite of my country's satellite mobile communication system. China's first independently developed mobile communication satellite covers 109 national territory points, with a design life of 12 years. The satellite orbit is E101.4 (above the equator south of Yunnan), and the ground station is located in Xi'an. It was officially operated by China Telecom in 2018.

The Tiantong-1 satellite covers China and its surrounding areas, the Middle East, Africa and other related areas, as well as most of the Pacific and Indian Oceans. There is no restriction on the terrain coverage, and the ocean, mountainous areas, plains, forests, Gobi and desert can all be seamlessly covered.

Advantages of Tiantong-1 Satellite Phone

▲Safety and autonomy

Tiantong-1 is China's first satellite mobile system satellite, with its own satellite, system and terminal, and no leakage problems. For information security considerations, especially in the military field, the autonomy of satellite mobile communications is an inevitable trend.

▲Reasonable charges: low cost of use

The cost of Tiantong satellite calls is lower than that of Maritime, Iridium and other systems.

The voice rate of my country's satellite mobile communications is 1.60 yuan per minute (outside of package), which is lower than other currently operating satellite mobile communication systems.

▲Satellite controllable

If an emergency situation arises that threatens the safety of the country and the people, on-site command and coordination of satellite resources is the most feasible option.

▲ Worry-free after-sales service

Tiantong satellite terminals and accessories are all domestically produced, and can provide customers with high-quality and thoughtful after-sales service.

Tiantong Satellite Phone Application Scenarios

▲Maritime Communications

Tiantong satellite phones are widely used in the sea and can be applied in scenarios such as maritime police, fishing boats, shipping companies, scientific expeditions, etc.

▲Industry Application

Industries such as petroleum, transportation, surveying and mapping, environmental protection, mining, meteorology, and forestry have an urgent need for satellite mobile communications in areas where ground communications cannot cover the field.

▲ Travel and adventure

Solve problems such as wilderness adventure tourism in uninhabited areas, communication problems during long-distance off-road trips, and rescue in distress in the wild.

▲Emergency Communications

In emergency communication scenarios, satellite phones can be used for common tasks such as flood control and disaster relief, forest fire prevention, and border patrols.

Tiantong-1 has been on its journey through space for 15 years. With the advantages of safety, autonomy, low satellite controllable cost and worry-free after-sales, it is widely used in many industries such as geological survey, field mapping, power line maintenance, long-distance transportation, as well as tourism adventure, emergency communication and other scenarios. Tiantong-1 satellite mobile communication system is China's own "maritime satellite" and also a national weapon. It has freed our country from its long-term dependence on foreign satellite mobile communication services and is no longer subject to the control of others.
