Icom’s IC-SAT100 allows users around the world to communicate with a group of PTT radios at the push of a button. To do this, the IC-SAT100 utilizes Iridium® satellite network covering the earth including both poles providing wide area global communication anywhere on the planet. 

These SAT100 radios use SATELLITE PTT (Push-To-Talk), which is a two-way radio system using the Iridium® satellite network. This network allows you to use 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, Icom 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 SAT100 provides low-latency communication, and broader, more reliable network coverage, compared to Geosynchronous Equatorial Orbit (GEO) satellites.
