UTair Helicopter Services, the largest helicopter operator in Russia has recently installed satellite tracking over their fleet. The new instalment was required by the United Nations, UTair’s biggest client since 1991. The trackers, made by British Rock Seven, are called RockSTAR trackers and can monitor the whereabouts of the entire fleet.

This is done by an intermittent signal that is sent to GLONASS (Global Navigation Satellite System) and GPS. This data is then transmitted by Iridium networks to a server where it can be accessed by any web browser, reports Russian Aviation Insider. The use of satellite tracking has become critical, as many pilots have to operate in areas where there is an unstable connection.
