Icom’s SATELLITE PTT (Push-To-Talk) is a two-way radio system using the Iridium® satellite network. This network allows you to use the IC-SAT100 Portable and the IC-SAT100M Mobile in remote, isolated areas without mobile phones or landline network infrastructure or if terrestrial network infrastructure is rendered unusable by human or natural disasters. Unlike satellite phones, IC-SAT100 users can immediately start talking to all the radios in the same talkgroup, with just a push of the transmit (PTT) button. Using 66 Low Earth Orbit (LEO) Iridium® satellites, the IC-SAT100 provides low-latency communication, and broader, more reliable network coverage, compared to Geosynchronous Equatorial Orbit (GEO) satellites.
Requires a monthly Talk Group fee and a monthly per unit airtime fee.
