Iridium Push-To-Talk
Instant Team Communication. Wherever Operations Take You.
Keep field teams, vehicles and remote sites connected with satellite Push-to-Talk communications over the Iridium network.
How Satellite Push-to-Talk Works
Iridium Push-to-Talk provides instant, one-to-many voice communication between team members using the Iridium satellite network. Instead of making individual phone calls, users simply press the PTT button to speak to everyone assigned to the same talkgroup.
Because communication is carried over satellite, teams can remain connected across remote and widely dispersed locations where cellular or conventional radio infrastructure may be unavailable.
PTT RADIO → IRIDIUM SATELLITE NETWORK → TALKGROUP → YOUR TEAM
When a user presses the PTT button, their voice is transmitted via the Iridium satellite network and delivered to other active users within their assigned talkgroup. Team members can be operating across different locations while remaining part of the same communications group.

Is Satellite PTT Right for Your Operation?
| Mobile Phone | Conventional Two-Way Radio | Satellite Phone | Satellite PTT | |
|---|---|---|---|---|
| Group communication | Limited | Excellent | Poor | Excellent |
| Remote coverage | Variable | Limited by infrastructure | Excellent | Excellent |
| One-button communication | No | Yes | No | Yes |
| One-to-many | Limited | Yes | No | Yes |
| Requires terrestrial infrastructure | Yes | Usually | No | No |
| Individual phone calls | Yes | No | Yes | Device-dependent |
Flexible Satellite Communications
Build a PTT Network Around Your Operation
Iridium Push-to-Talk can be configured around the way your organisation actually works, connecting teams across remote sites, offshore assets, vehicles and control centres within a structured communications network.
One Network. Multiple Operational Areas.
Connect dispersed teams through shared Push-to-Talk communications.

Separate coverage areas can be configured within a single talkgroup
2.25m km²
Maximum geographical coverage configuration for a talkgroup

Talkgroups can be assigned to an individual compatible handset
Using the Iridium PTT Command Center, administrators can define geographical operating areas, assign devices to talkgroups and structure communications around teams, locations or operational responsibilities.
A single talkgroup can contain multiple geographical coverage areas, allowing personnel working hundreds or even thousands of miles apart to remain part of the same operational conversation.
Individual devices can also belong to multiple talkgroups. This means the same user could communicate with a day-to-day operational team while also having access to dedicated emergency, management or logistics talkgroups when required.
Structure Talkgroups Around Your Teams
Talkgroups can help separate everyday operational communications from specialist or emergency conversations, ensuring the right people can communicate with the right teams.
Talkgroup 01
Field Operations
Connect operational personnel working across multiple active sites.
London HQ → Scotland → Offshore Platform
Talkgroup 02
Emergency Response
Create a dedicated communications group for incidents requiring rapid coordination.
Supervisors → HSE → Security
Talkgroup 03
Logistics
Keep personnel responsible for movement, supply and remote support connected.
Vehicles → Warehouse → Remote Sites
Your PTT network doesn't need to follow a one-size-fits-all structure. It can be configured around your locations, teams and operational responsibilities, helping ensure that the right people have access to the right communications when they need them.
iridium push-to-talk faqs
Iridium PTT is a satellite-based group communication service that allows users to speak instantly with individuals or teams using a push-to-talk button, similar to a two-way radio but with near-global coverage.
PTT enables instant, one-to-many communication without dialing numbers. It’s designed for quick team coordination, whereas satellite phones are better suited for one-to-one voice calls.
Iridium PTT operates over the Iridium satellite network, providing near-global coverage, including polar regions, oceans, and remote land areas where traditional radio or cellular networks are unavailable.
No. Unlike traditional radio systems, Iridium PTT does not require local infrastructure such as towers or repeaters. Communication is handled entirely via satellite.
Yes. Iridium PTT supports group communications, allowing multiple users to be assigned to talkgroups for coordinated team operations across wide geographic areas.
Dedicated PTT devices like the Iridium Extreme PTT and Icom IC-SAT100 are designed specifically for this service, offering rugged, field-ready communication with simple operation.
Yes. PTT is widely used by emergency services, security teams, and remote workers who need instant, reliable communication across dispersed locations.
Iridium PTT includes secure communication features, with controlled talkgroups and managed access, making it suitable for professional and operational use.
Yes. Iridium PTT services require an airtime plan, typically based on user access and usage, allowing organisations to scale communication across teams.
Iridium PTT provides instant communication, near-global coverage, no infrastructure requirements, and scalable group coordination, making it ideal for remote operations, field teams, and mission-critical environments.
