OEPS-29

Description: The OEPS-29 is an electro-optical sighting system designed to search and track airborne targets following its infrared emissions. The OEPS-29 Infrared Search and Track System (IRST) connected to a pilot's helmet-mounted target designation system provides unmatched performance during close-range air-to-air engagements, also referred to as dogfight. This electro-optical system is also suitable for designation of ground targets based on infrared/heat emissions. In addition to the IRST capability, the OEPS rangefinding capability using a built-in laser.

Basically, an OEPS system consists of four items: infrared thermal sensor, helmet-mounted target designator, laser rangefinder and a computer. The OEPS-29 was designed for integration into the Soviet/Russian Mig-29 aircraft family providing IRST capability day/night, at all altitudes and with intense enemy Electronic Counter Measures (ECM) in both modes, lookup and lookdown. It provides a coverage of -30 to +30 degrees in azimuth and -30 to +15 in elevation and weighs 78 kg. Compared to Su-27's OEPS-27, the OEPS-29 is lighter and has a downgraded coverage.
