  1. TV Optical Head Description :TV Optical Head GIG No. :348479 Sec Ref No. :810PGW Part No. :G-3435818 Cost :Rs. 10, 92, 720/-(Assessed) 7B/PECHORA/SNR-125/PR/01/06-11 Qty-07 (1st & 2nd line servicing requirement)

  2. COMPOSITION OF TV OPTICAL TRACKER TV optical tracker used in Pechora (MGR) is comprised of the following components: (a) Optical section (Optical head) (b) Light to signal converter (vidicon tube) (c) Video channel (d) Signal to light converter (picture tube ) (e) Scanning devices & (f) Synchronizing device

  3. FUNCTION OF THE ITEM To enhance the operational capability of Pechora (MGR) under anti radiation missile attack and EW environment, Pechora MGR has been provided with facility for optical tracking of the target.

  4. LOCATION ON THE MAJOR ASSEMBLY TV camera is located on the YHB post And display units in the cabin.

  5. ROLE IT PLAYS TV optical system is intended for observations of remote objects and determination of their angular co-ordinates. There are two types of CC TV namely 9 Sha 33 A and 9 Sha 38-1 used in Pechora MGR. 9 Sha 38-1 TV optical tracking system is also used in OSA-AK & SPAGU weapon system of Army.

  6. LOAD IT TAKES 220 V±5%, 400Hz±2.5% ±27V±10% Power Consumption:- Max 450VA for 220V 400Hz mains Max 200W for 27V mains

  7. THE EFFECTS OF ITS FAILURE During Anti Radiation Missile attack and EW environment the target can not be tracked without the help of TV system.

  8. ASPECTS THAT MAKE IT NON-FEASIBLE/COMPLEX OR DIFFICULT FOR INDIGENISATION Adaptability to the existing Radar system and availability of a system which has night/ IR capability and limitations of tracking range.

  9. TECHNICAL AND FUNCTIONAL SPECIFICATIONS

  10. LIMITATIONS TV camera can not be operated during night due to its limitations which affects the operational capability of the squadron during night in case under ARM attack and EW environment.

  11. FEATURES TO BE IMPROVED • Existing Range and field of vision of • angle needs to be improved. • (b) Resolution needs to be improved. • (c) Night operation facility needs to • be incorporated. • (d) Operating temperature range, relative humidity and continuous operation limit should be at least as per existing system.

  12. FUTURE REQUIREMENTS If night operation facility can be successfully incorporated, the complete Pechora & OSA-KA fleet will require the new system. Considering the number of FUs of Pechora and OSA-AK, the requirement may be 50 No.s of cameras.
