In 2015, Iridium launched a Push-to-Talk service. Iridium PTT immediately received the "Top Emergency Response Innovation" award at SATELLITE 2016. For more on that see the Mobile Satellite Users Association 2016 Mobility Satellite Innovation Awards. Iridium PTT uses mobile handheld satellite phones instead of the bulky terminals currently used by Light Squared (MSAT) or Inmarsat BGAN based push-to-talk services.
