Latvia to test new TPS-77 MRR radar

The Latvian National Armed Forces (NAF) will finalise the delivery of the first TPS-77 Multi-Role Radar (MRR) by testing the system’s air surveillance capabilities, the Latvian Ministry of Defence (MoD) announced on 8 March.

The Latvian MoD signed a contract with Lockheed Martin for the production of three TPS-77 MRR units in 2015 to enhance the air surveillance capabilities of the Latvian Army.

The Latvian variant of the TPS-77 MRR can be truck mounted for operation at unprepared sites or dismounted for use at fixed sites.

The TPS-77 MRR’s multi-role single scan technology allows operators to select specific roles for the radar such as long range or medium range low-level flight surveillance in specific sectors. As the radar rotates through each 360 degree scan, the system automatically adjusts to the operator selected mission. Changes can be easily made, and once the radar is set, no further operator inputs are required.

The TPS-77 MRR uses Gallium Nitride technology, which enables the radar’s high power amplifiers to consume much less power, lowering life-cycle costs and extending the useful life of the radar.

Latvia already has three AN/TPS-77 radars at the Čalas, Lielvārde and Audriņi surveillance radar stations. The radars have improved the airspace security and efficiency of air traffic surveillance and coordination for search and rescue operations.
