Frequently Bought Together



ICOM IC-SAT100 Push-To-Talk (PTT) Iridium Satellite Radio uses the Iridium network to provide users coverage anywhere in the world. This two-way radio system can be used as a communication tool in remote, isolated areas where there are no mobile phones or landline network infrastructure. Even if terrestrial network infrastructure is rendered unusable by human or natural disasters, this Push-To-Talk can provide a stable backup, independent from other networks. ICOM IC-SAT100 PTT is your complete source for two-way radios and Push-To-Talk solutions.

One-to-Many Communications

Unlike satellite phones, ICOM IC-SAT100 Push-To-Talk owners can start talking to all the radios in the same talk group instantly, with just a push of a button (PTT).

Global Coverage

The Iridium satellite network covers everywhere, including both poles and can provide wide-area global communications*.

Real-Time, Low-Latency Communication

Using 66 Low Earth Orbit (LEO) Iridium satellites, the Icom IC-SAT100 Satellite PTT Radio provides low-latency communication, and broader, more reliable network coverage, compared to Geosynchronous Equatorial Orbit (GEO) satellites. In fact, the latency is so low that the delay is approx. 500 milliseconds. 

Emergency Functions

The built-in orange key can be used for emergency situations (located on the top panel). You can transmit an emergency call to preprogrammed users by pushing down the key.

Waterproof, Dust-tight and Durable Body

The IC-SAT100 provides IP67 waterproofing (1m depth of water for 30 minutes) and dust-tight protection, making it ideal for use in harsh outdoor environments. The radio also meets MIL-STD 810G specifications. The operating temperature range is from –30°C to +60°C (–22 °F to 140 °F).

1500 mW Powerful Audio

1500 mW audio delivered from the internal speaker provides loud and clear communication, even in noisy environments.

Battery Life

The supplied BP-300 Li-ion battery pack provides 14.5 hours of operation.

Private Conversations

The Icom IC-SAT100 Satellite PTT Radio provides secure conversations with AES 256-bit encryption.

Conventional Radios and IP Phones Interconnection

With a VE-PG4 RoIP gateway, the IC-SAT100 can interconnect with an IP phone, IP, LTE, IDAS digital*1 and analog transceivers. ICOM IC-SAT100 PTT two-way radios have a wide range of features and portable device.

How does it work?

Using satellite Push-To-Talk technology, users of the ICOM IC-SAT100 can communicate with any other IC-SAT100 radios that are assigned to the same talk group. The coverage for the talk group must be pre-selected and coverage areas can be split into different coverage regions.
