find distributors



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 Communications

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.

Power supply capability over Ethernet from main unit to antenna (with RF unit)

LAN cable (CAT5e) accepts up to 100 m cable connection (from main unit to antenna with RF unit) without any sensitivity loss and thin cable allows easy wiring work

Supplied multi-functional speaker-microphone

Power supply requirement: 13.2 V/26.4 V DC

Waterproofing and dust-tight protection: IP67 (antenna with RF unit), IP55 (mic), IP54 (main unit)

Other Features

  • Voice Recording function
  • Built-in Bluetooth® capability
  • Multiple language display ( English, C hinese, French, Japanese, a nd Spanish)
  • Integrated GPS receiver shows received signal position information on the display
  • 1500 mW powerful audio output
  • Short Data Message
  • AES 256-bit encryption*

*Communication data is scrambled in the Ethernet section to prevent casual eavesdropping.

Supplied Accessories

  • Multi-functional speaker-microphone
  • OPC-585 DC power cable
  • OPC-2102 LAN cable (20 m, 65.6 ft)
  • Mobile bracket

Installation Examples

In-Building Use
You can flexibly install the radio and the antenna with only a LAN cable (Maximum 100 m, 328 ft).


Mobile Use
By attaching the antenna on the roof, you can use the radio in a vehicle. The IC-SAT100M has Bluetooth® capability, and allows hands-free operation* while driving.

*A third party accessory required.

Advanced System Examples

Low Visibility Installation for Mobile Use
The optional AH-40 antenna provides flexible antenna installation. You can replace the antenna with AH-40, and mount it on the roof instead of the RF unit. 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 I use the IC-SAT100M in any location?

The IC-SAT100M can be used in open spaces, like the rooftop of a building. Receiving and transmitting may fail, depending on the satellite position or any obstacles between the radio and satellites. Your body can also be an obstacle. Hook the radio upright on your shoulder rather than on your waist.

Can the IC-SAT100 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.
