New navigation system for the Т-50

Russia’s Radioelectronic Technologies Concern is demonstrating its latest strap-down inertial navigation system, designated BINS-SP2, which is already installed on two aircraft flying here at the air show: the Sukhoi Su-35S multirole fighter and the Sukhoi T-50 fifth-generation fighter. 

The BINS-SP2 architecture is based on three laser gyroscopes and three quartz accelerometers. The system can establish the platform’s coordinates and motion variables in the absence of external data inputs.

The system was developed by Moscow Institute of Electromechanics and Automatics, a subsidiary of Radioelectronic Technologies. General director Alexey Kuznetsov says the BINS-SP2 can operate at temperatures between –60° and +60° C, and at altitudes up to 25 km.

Anatoly Chumakov, general director of the BINS-SP2 manufacturer Ramenskoye Instrument Making Plant, predicts great demand for the system from military and civilian customers. Three examples per airframe could be installed on civilian aircraft, and two per airframe on warplanes. The system has a service life of 10,000 hours. It can also be used on sea vessels and road transport.
