Satellite communication terminal equipmentSatellite communication terminal equipment is a device in the user segment of the mobile satellite communication system, including Mobile device and hand-held terminal.
In terms of types, there were many satellite communication terminal devices in different application scenarios. For example, in the Aerospace Mobile Satellite System (AMSS), the receiving and transmitting equipment on the aircraft belonged to the aerospace mobile satellite communication terminal. It was composed of a satellite data unit (SDIU), a radio frequency unit (RFO), a high power amplifier (HPA), and an antenna. It was used to provide voice and data communication between the aircraft and the ground for the crew and passengers. It was required for functions such as cockpit voice, data, automatic position and status reports, and passenger direct dial phones.
The satellite communication terminal of Tongyu Communication (002792.SY) was mainly a mobile communication antenna, such as a ship-borne satellite antenna, a car-mounted satellite antenna, etc.
There were also popular smart phones such as the Huawei Mate X6 Triple-Network Satellite collector's edition, which were also satellite communication terminal equipment. It was the world's first popular smart phone that supported triple-network satellite communication. It could communicate with the outside world through Tiantong Satellite Communication, Beidou Satellite News, and low-orbit satellite Internet.(The low-orbit satellite internet system was being tested and was expected to open in the second half of 2025.) It could realize communication functions such as sending edited text messages, receiving text messages, sending picture messages, sending positioning and action trajectories composed of positioning, making and receiving satellite phones, satellite pagers, and so on.
Glory had also made a breakthrough in satellite communications technology. The results could be applied to future smart terminal devices (such as Glory Magic6), enabling them to have satellite communications capabilities. The antenna size, power consumption, and communication stability were optimized, entering the era of "ground + satellite" dual communications.
In addition, there were satellite communication terminal devices such as the Beidou satellite positioning smart badge on the market, as well as small satellite Mobile device such as satellite phones. They were relatively cheap and could allow ordinary mobile phones to have satellite phone functions.
In terms of basic composition, the main units of the satellite terminal, including the satellite transmission unit, image coding unit, voice coding unit, etc., can all be combined in a portable box. The terminal provides a rich data interface for computers, cameras and other external devices to access the terminal. Its radio frequency output and input can be different frequency bands, which can be adapted to various mainstream antenna units at home and abroad. The satellite communication portable terminal could provide users with a portable multi-service satellite communication platform, so that users could easily establish satellite communication links with the command center or other terminal to transmit images, voice, data and other services, no matter where they were. It mainly provided satellite phones, image acquisition and transmission, two-way video calls, file transmission, remote network access, data transmission and other functions. In the military, the miniaturized satellite communication terminal could be operated by a single soldier or in the form of a vehicle. It could be used in the L-band (1 to 2 gigaHertz), X-band (8 to 12 gigaHertz), Ku-band (12 to 18 gigaHertz), and Ka-band (26.5 to 40 gigaHertz).
