Mobile satellite SMS is a technology that communicates through satellites, allowing users to send and receive SMS in areas without ground base station coverage. Its principle:
User end devices: Firstly, users need to have a mobile phone or terminal device that supports satellite communication. These devices typically have additional satellite communication antennas for communication with satellites.
Ground equipment: On the ground, there are some ground stations or ground control equipment that are responsible for communicating with satellites.
Satellite link: Satellite link is the key to mobile satellite SMS. A group of communication satellites orbiting the Earth are responsible for forwarding communication between user terminal equipment and ground equipment. The user’s message is sent to the satellite and then transmitted from the satellite to ground devices.
Encoding and decoding: During the communication process, messages are encoded and decoded to ensure their integrity and confidentiality. These encoding and decoding processes are part of satellite communication to ensure the reliability of communication.
Ground device and target terminal: Once a message reaches the ground device, it will be forwarded to the target terminal device, which can be another satellite phone or a device connected to a traditional mobile network.
