Global satellite Push-to-Talk (PTT) communications from your aircraft cockpit

What is Iridium PTT?

Iridium® PTT uses Iridium's constellation of 66 cross-linked, low-earth orbit satellites to provide rapid and secure one-to-many communications between people anywhere on the globe.

Using an Iridium® PTT command center you define coverage areas and user talkgroups. As  situations evolve you can make changes that are carried out within seconds. In any talkgroup you can define up to 10 service areas located across the globe. Interoperability allows different organisations to communicate when they need to. Iridium PTT comes with AES-256 encryption –  one of the most secure standards available.

Switch rapidly between phone and PTT mode

Flightcell DZMx switches between the standard phone mode and PTT mode at the push of a button.
Finish a person-to-person call, switch modes, and a few seconds later you can be talking to a team of people. The reverse also applies.

Aircraft equipped with DZMx PTT have global communications with:

  • Other aircraft with DZMx PTT
  • Ground units using Iridium® Extreme PTT handsets
  • Vehicles equipped with DZMx PTT
  • Command posts with DZMx PTT ground stations
