ICOM IC-SAT100 & IC-SAT100M – Global Iridium Satellite Push-to-Talk Radios
The ICOM IC-SAT100 Handheld and IC-SAT100M Mobile Fixed radios are advanced satellite-based communication tools. These devices use the Iridium satellite network, which covers the entire globe, including oceans and polar regions. Designed for critical communication, they support Push-to-Talk (PTT) technology over satellite, providing instant voice communication across long distances.

Why Choose Satellite PTT Communication?
Traditional radios have limited range. However, the IC-SAT100 and IC-SAT100M operate via the Iridium network. Therefore, you can connect with your team anywhere on Earth. Whether you’re on a ship, in remote mountains, or in the Arctic, communication stays stable and reliable. Furthermore, these radios support secure, encrypted channels, which are essential for safety and security in critical environments.
