mobile satellite
Mobile satellite communication was a technology that used communication satellites to enable mobile phones to communicate with the outside world. As early as 1958, the United States launched the world's first communication satellite, the Skor, which kicked off the application of global communication satellites. In 1975, China launched the "331 Project" to develop communication satellites. In 1984, it launched the first experimental communication satellite in the stationary orbit,"Dongfanghong-2." In 2021, China built a full-scale and complete Tiantong-1 satellite mobile communication system. In addition, China's Beidou positioning satellite also has the ability to send and receive short messages in both directions, namely Beidou short message function. In terms of mobile phone applications, in 2022, Huawei released the Mat50 series mobile phone, becoming the world's first popular smartphone to support Beidou satellite news, opening the process of satellite communication entering the field of mass consumer electronics. After that, domestic brands such as Glory, Xiaomi, Oppo, and Vivo, as well as Apple, also launched mobile phones that supported satellite communications. However, mobile satellite communications had some limitations. For example, compared with ground base station communication, satellite call transmission delay is larger (such as synchronous satellite communication has a delay effect of about 0.5 seconds), and there are prerequisites for the use of mobile satellite communication functions. For example, some of them require China Telegram cards and have to be activated, and they usually need to be used outdoors in an open area. China United was also involved in the field of satellite communications. Its subsidiary, China United Airlines, launched the "Pioneer Phased Array" satellite communication terminal and made progress in low-orbit satellite communication. It completed the first non-terrestrial network (NRNTN) low-orbit in-orbit test for domestic operators and verified the functions of the terminal directly connected to satellite communications.
satellite mobile phone
A satellite phone was a communication device based on a satellite communication system that used artificial satellites as relay stations to relay radio signals, thereby communicating between two or more Earth stations. Different from traditional mobile phone networks, it could provide highly stable communication services in areas that were difficult to cover by ground mobile communication systems (such as forests, deserts, oceans, etc.), as well as areas where ground mobile communication systems were interrupted due to natural disasters (earthquakes, tsunamis, fires, etc.). It had the advantages of large coverage area and high deployment flexibility. Its communication system mainly includes communication satellites, ground monitoring stations, communication earth stations (gateway stations), satellite phones, etc. The communication satellite was responsible for relaying, relaying, or regenerating communication signals. The ground monitoring station was responsible for satellite tracking, remote measurement, remote control, status monitoring, and position maintenance. The communication earth station was responsible for receiving and transmitting signals between the user and the satellite. It could be set up on land, sea, or in the air. The satellite phone was directly used by the user to establish a communication link between the user and the communication earth station or between the user and the satellite. The mainstream satellite communication systems could be divided into low-Earth orbit satellite systems (LEO) and geo synchronous orbit satellite systems (GSOs). Low Earth Orbit Satellite (LEO) technology can provide global seamless wireless signal coverage. Orbit the Earth every 70 to 90 minutes (640 to 1120km), but more satellites were needed to maintain signal coverage; the GFO system only needed three to four satellites to maintain global signal coverage almost all day long, reducing the cost of launching satellites. However, the satellite was heavy (about 5 tons), so the cost of building and launching a single satellite was high. Moreover, when it operated at an altitude of 35000km, the delay phenomenon was obvious when talking or transmitting data. At present, many mobile phones began to support satellite calling functions. For example, in August 2022, the Huawei Mat50 series mobile phone provided emergency communication services based on Beidou satellite navigation system, and in September 2022, the Apple iPhone 14 mobile phone supported satellite phone function to provide emergency communication services; Nubian Z60S Pro is priced at more than 2K and has two-way satellite communication; Glory Magic V3 dual satellite version will become the first Android mobile phone to support Beidou + Tiantong dual satellite communication; For the first time, Huawei introduced a satellite messaging function on the Mate50, which could link to the satellite to send short messages when there was no network. However, there were also cases in the market where OBEE satellite phones caused a storm due to false and exaggerated publicity (claiming that calls were free, etc.). The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!

Satellite communication cell phones need to search for satellite networks. 3. ** antenna **: Satellite communication mobile phones need a long antenna to receive signals. The antenna of ordinary mobile phones cannot be seen. 4. ** Function **: Satellite communication mobile phones are mainly functional and do not have entertainment functions. Ordinary mobile phones have various functions, including entertainment functions. 5. ** Communication quality **: Satellite communication mobile phones are not affected by natural disasters on the ground. The communication quality is stable and the coverage is wide. Ordinary mobile phones may have poor communication quality when encountering natural disasters on the ground. 6. ** Adding an antenna **: Satellite communication mobile phones generally need to be equipped with an outdoor antenna to receive signals stably. Ordinary mobile phones do not need it.
How much does mobile satellite communication cost?
Take Beidou Messenger as an example. It was priced at 999 yuan, including three-year fees (including 1500 free communication services). The initial discount price was 799.1 yuan. In 2024, there was a 50% discount on Double Eleven, which was only 399 yuan. Different satellite communication phones or devices may have different charging methods. For example, some mobile phone satellite communication functions are exclusive to top-tier models and need to be purchased at an additional cost, but the specific amount is not available.
