The 1S12 SOC (Long Track) tracks the target similarly as the modern digital radars (ST-68U [Tin Shield]) do, just they do it for several targets parallel. It first measures the (X/Y/H)"0" coordinate of a target, than during the next sweep, finds the closest target to that coordinate. This will be the (X/Y/H)"1" coordinate. With a quick math, delta(X/Y/H) is determined. During the third sweep, it looks for the closest target at (X/Y/H)"1" + delta(X/Y/H). That will be (X/Y/H)"2", and the difference from (X/Y/H)"1" is again delta(X/Y/H). etc... If "Long Track" is a 3D radar, why they're using height-finders?

[video:youtube] http://youtu.be/clLlp4SDXyo?t=9m43s[/video] "Long Track" means two* radar types, and non of these are 3D in today sense**. 1RL128 P40 - with height finder, used for fighter guidance, and at SAM Brigade level. 1S12 SOC - without height finder, used at KRUG/KUB battalion level. *easy way to differentiate between these sets from the outside, is to count vertical stiffeners in the antenna. P40 has 9, while the SOC has 14. **SOC has azimuth, range, and coarse elevation information. For the SNR with elevation scanning it is enough, for a successful fighter guidance it is not.

On video they are 1S12 SOC and a PRV (-9 or -16)...

Hi. So I'm here to report some progress for those who are interested. Just recently we managed to get the hydraulic counterbalance system (on 2P24) working, luckily the whole automatic still works so it wasn't such a big deal in the end. I took a video of operation. Unfortunately the camera recording the actuator wasn't on so I only have pictures. Hopefully I'll take a better video next time. If I feel like unscrewing 20 screws while taking off the covering.... So here it is. The purpose of the system is to balance the weight of ty rocket by hydraulic pressure (around 12MPa). In the first picture you can see the whole setup (there are two total - one for each rocket). The green big thing at the top is an accumulator, under it there is a hydraulic pump and it's motor and there is an oil tank at the left corner. The second picture shows the piston of the pneumatic accumulator when unpressurized and the last picture when it's pressurized (fully in). The accumulator also serves as the pressure switch (microswitches on the piston itself). And finaly a video of the operator's panel during the operation. The pump takes around 300A of current while near the end of the cycle, that's why only one pump can run at the time. This part of the system doesn't need the AC supply so it works only from batteries (27V starting power source in our case).
