The Rock Seven RockBLOCK 9603 works with the Iridium Satellite System and the Rock Seven Servers to connect you between two points on Earth via space. That's right. That little square thing is talking to outer space!

The graphic above provides a general overview of the whole system. In the middle is the RockBLOCK 9603 modem itself. Data can flow in either direction.

1. The RockBLOCK 9603 communicates with the Iridium satellites to send/receive data.
2. The Iridium satellites communicate with ground based stations to send/receive data between space and Earth.
3. Data is sent between the Iridium ground stations and the Rock Seven Servers. You can access this server via a web interface.
4. Your specific application talks to the Rock Seven servers.
