Is Satellite Communication an Option for Off-Grid Ham Operators?

Choosing a Satellite Communication System

Off-grid ham operators can opt for satellite communication systems that cater specifically to ham radio enthusiasts. Some popular options include the Iridium satellite network and the Globalstar satellite system. These systems offer a range of devices, such as handheld satellite phones, satellite modems, and antennas, which can be integrated with ham radio equipment. For example, the Iridium 9555 satellite phone can be paired with a ham radio transceiver to enable satellite-based communication. Off-grid operators can also consider satellite-based Morse code systems like the APRS (Automatic Position Reporting System) which allow for the transmission of position and status information.

Setting Up and Operating a Satellite Communication System

Setting up a satellite communication system requires careful consideration of several factors, including the type of device, antenna selection, and power requirements. Off-grid operators should choose a device that matches their power generation capabilities and can operate within the available frequency range. For instance, the Globalstar system typically operates on a frequency range of 1.2-1.3 GHz, while the Iridium system operates on a frequency range of 1.5-1.6 GHz. Off-grid operators should also ensure that their satellite communication system is properly aligned with the geostationary satellites in orbit, which requires a clear view of the southern horizon.
