How Satellite Texting Works: A Simplified Explanation
The process of satellite texting involves several key components:
- User Device: This could be a dedicated satellite texting device, a smartphone with satellite connectivity capabilities (like the iPhone 14 and later), or a compatible satellite communicator.
- Satellite Network: These are constellations of satellites orbiting the Earth, typically in low Earth orbit (LEO) or geostationary orbit (GEO).
- Ground Station: Ground stations receive signals from the satellites and relay them to terrestrial networks.
- Recipient Device: The recipient can receive the text message on a regular smartphone or another satellite texting device.
The user device sends a text message, which is then transmitted to a satellite. The satellite relays the message to a ground station, which then routes it to the recipient’s device via the cellular network or another satellite network, if the recipient is also using satellite texting. The return process is reversed.
