DeLorme said the inReach device was designed to maintain a satellite signal lock even in difficult GPS environments and to wirelessly interfaces with Google Android and Apple smartphones. The inReach device operates over the Iridium satellite network.

   “The two-way communication features of inReach allow aircraft pilots to stay connected via text messages and email while flying routes beyond cell phone range. It can be used in stand-alone mode to send pre-loaded text messages, trigger SOS alerts, receive delivery confirmation and enable tracking, all from the pushbutton and LED interface,” DeLorme said in a company statement.
