SVK - P-37MSK (1RL139MSK, 3D rádiolokátor)

P-37MSK (1RL139MSK) is a 3D radar created by modernization of radars P-37 OS SR on the standard of the Russian radar 1L117.


The modernization is carried out in LOBB Banská Bystrica in close cooperation with the owner of the know-how - the company LEMZ Moskva, which is also the main supplier of components. In contrast to the Russian radars, the P-37MSK radar (1RL139MSK) has an integrated recognition system (IFF) MSR2000 compatible with NATO systems according to STANAG 4193, MARK X, MARK XII standards of the German company EADS Munich.


The P-37 radar has retained a trailer with a platform 52-U-415M with a cabin and a support-rotating system, supplemented by new equipment:
- primary radar antenna-waveguide system,
- 6 channels of transmitters and receivers,
- signal processing and command transmission equipment,
- secondary radar antenna system (IFF),
- IFF device MSR 2000I.


The indication cabin is realized on the basis of new parts stored in a standardized ISO 1D container. The container contains:
- radar remote control and synchronization equipment,
- two operator stations with circular horizon indicators and primary and secondary signal processing equipment,
- power supply control blocks,
- communication, communication and ancillary equipment,
- VIP-117M profitable indicator, which can be located in the indicator cabin or at the command post.


The radar also includes a source trailer, which provides power to the radar either from the public network or from a backup source consisting of a pair of PETRA 57 CGB generators. other components of the source trailer are the modernized frequency converter VPL-30D-M1U2 and the control and management system of the source trailer. All devices are integrated on one original source trailer.


The original transport trailer is repaired and adapted to transport antenna system parts, accessories and spare parts.



The abbreviation MSK means: M - modernized, SK - Slovakia
