This receiver can be used in a civilian aircraft as a primary means of navigation during en-route, terminal, approach, and landing. This is the first and so far only certified aerospace GPS-SBAS receiver of its class conforming to the latest FAA standards. An aerospace GPS receiver is characterized by extreme reliability, high accuracy, and very good availability. Of these, reliability is the most important factor. That is achieved by creating a very reliable hardware and software.
