GNSS Receivers process the Signals In Space (SIS) transmitted by the satellites, being the user interface to any Global Navigation Satellite System (GNSS). Even though the information provided by a generic GNSS receiver can be used by a wide range of applications, most of them rely on the receiver’s navigation solution – i.e. receiver computed Position, Velocity and Time (PVT).

GNSS receivers determine the user position, velocity, and precise time (PVT) by processing the signals broadcasted by satellites. Because the satellites are always in motion, the receiver has to continuously acquire and track the signals from the satellites in view, in order to compute an uninterrupted solution, as desired in most applications.

Through its McMurdo brand, Orolia announced its global aeronautical distress safety system (GADSS)-compliant distress tracking emergency locator transmitter (ELT–DT). The product, known as the GADSS ELT–DT, performs autonomous tracking of commercial aircraft in distress through processes such as trigger-in-flight capability. This allows for the beacon to automatically transmit a distress signal with the aircraft’s accurate position. Read more…
