Satellite PTT

Icom’s IC-SAT100 radio uses Satellite PTT (Push-To-Talk), which is a two-way radio system using the Iridium Satellite Network. This network allows you to use the IC-SAT100 in remote, isolated areas without mobile phones or landline network infrastructure or if terrestrial network infrastructure is rendered unusable by human or natural disasters.

One-to-Many Communications

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.

Real-Time Low-Latency Communication

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.
