One-to-Many Satellite Communication for In-Building and In-Vehicle Use


The Icom IC-SAT100M is the dedicated satellite push-to-talk (PTT) radio, and is the only PTT radio offering real-time communications at the push of a button between a group of individuals, each of whom can be anywhere on the planet*. The IC-SAT100M uses the Iridium® satellite communication network, which covers the entire globe, including both poles.

* Subscription contracts are required for using the IC-SAT100M. Depending on the country or region, carrying and/or use of the IC-SAT100/M may be prohibited.

One-to-Many Communication

IC-SAT100M users can immediately start talking to all the radios in the same talkgroup, with just a push of the transmit (PTT) button. 

Total Global Coverage, Including the Poles

The Iridium® satellite network covers the entire globe, including both poles, and can provide global communications anywhere on the planet*.

* Subscription contracts are required for using the IC-SAT100M. Depending on the country or region, carrying and/or use of the IC-SAT100/M may be prohibited.

Real-Time Communication

Using 66 Low Earth Orbit (LEO) Iridium® satellites, the IC-SAT100M provides low-latency communication, and broader, more reliable network coverage, compared to Geosynchronous Equatorial Orbit (GEO) satellites.

Interoperability with Conventional Radios


With a VE-PG4 RoIP gateway, the IC-SAT100M can interconnect with an IP phone, WLAN, LTE, IDAS digital*, analog transceivers and other communication systems.

* Type-D multi-site trunking and conventional systems.

Install the antenna unit (with RF unit) to the rooftop, and use the radio from indoors, or even from the basement

Easy wiring works between the antenna unit (with RF unit) and main unit using a LAN cable (Cat 5e)*1

Compatible with both 13.2 and 26.4 V DC vehicle power source

Antenna unit with RF unit: IP67, Main unit: IP54, Microphone: IP55

1500 mW powerful audio output

Other Features

  • Voice Recording function

  • Integrated GPS receiver shows received signal position
  • Short Data Message
  • AES 256-bit encryption for security
  • Tested to the MIL-STD-810 environmental tests

*1 User supplied LAN cable is required to replace the supplied 20m LAN cable.
*2 Version without Bluetooth® also available. Ask your Dealer for details.

Installation Examples

In-Building Use

You can flexibly install the radio and the antenna (with RF unit) with only a LAN cable (Maximum 100 m, 328 ft). Using PoE (Power over Ethernet) capability, the main unit supplies power to the antenna unit through the LAN cable. Connect your PoE injector or switch to extend the distance between the main unit and the antenna unit. (802.3at compatible)
* User supplied LAN cable is required to replace the supplied 20 m LAN cable.

Installation for Mobile Use

For a vehicle use, optional AH-40 must be used for optimal performance and environmental resilience. It must be placed on the top of the roof (highest point) with least sky blocking objects around. When you use a third-party antenna cover, you can cover the AH-40 making it look more discreet.

Advanced System Example with VE-PG4

The VE-PG4 is a versatile RoIP (Radio over IP network) gateway unit, which seamlessly interconnects satellite PTT radios, PMR radios, LTE radios, WLAN radios, IP phone systems, and external devices. In addition to the IP Network (LAN/WAN), the built-in LTE module* provides virtually nationwide communication coverage.

*Service availability depends on the country. Network coverage provided by a custom SIM card.

Q & A

What about communication fees

Communication fees are typically charged at a flat rate through a monthly plan, and there are no additional call charges.* Communication fees differ, depending on the coverage area and the number of the IC-SAT100M.

* Depending on the country or area, a flat charge plan may not apply, or the service may not be available.

What is a "Talkgroup"?

Using SATELLITE PTT, you can communicate with other IC-SAT100M radios assigned to the same Talkgroup. The coverage area of the Talkgroup is selectable from five sizes (see the table above).

How do I assign a coverage area?

The coverage area can be split into different coverage regions, using circles, squares, and rectangles. For example, you can assign coverage areas to Tokyo, New York and London.

Can I change my Talkgroup and/or the region within a coverage area?

Yes, you can flexibly change these settings* on the Iridium® website.

* To change the contents of a contract may require an application in advance.

Can the IC-SAT100M make phone calls?

No, the IC-SAT100M is PTT (Push-To-Talk) use only. Using the optional VE-PG4* RoIP gateway, the IC-SAT100M will be able to communicate with other networks.
