Intended to determine and outout flight and navigation data of aircraft. INS-80 is made as a single unit comprising a gyro-stabilized platform, platform electronics, a computer and I/O device units.

Two free dynamically tuned gyros and three accelerometers are mounted on gyrostabilized platform. The electronics is mounted on separate removable printed-circuit boards based on integrated micro-circuits and micro-assemblies.

The system keeps it's workability at all attitudes of aircraft.
