Our signal is broadcast over three Inmarsat satellites, offering coverage on continents and on the open seas. These three birds are:
- I-4 F1 APAC (Asia-Pacific), at 144-degrees East
- Alphasat, at 25-degrees East
- I-4 F3 Americas, at 98-degrees West
Our frequencies are:
- APAC: 1545.9525 MHz
- Alphasat: 1545.94 MHz
- Americas: 1539.8725 MHz
Bitrate is about 2kbps, or 20MB of content per day.
Outernet L-Band hardware can also be used for Inmarsat reception, including SafetyNET, EGC, and AERO.
Outernet uses a portable L-Band patch antenna. This directional antenna has a beam width of 40 degrees, so pointing is easy. Just aim in the general direction of the satellite.
This antenna is housed inside Lantern, but if you are more of a do-it-yourselfer, you may buy an antenna to build your own receiver.
