Funny they say things like optical sight , compass , ww2 equipment etc ,
Russia has OptoElectronic Satellite that can generate upto date digital
maps , it has reco assets like aircraft that can do mapping/targetting
,plus you have inertial guidance etc
Well it does, but with voice only communication to the troops in the field and no individual GLONASS receivers telling them where they are they would have to rely on maps and compasses and a bit of maths. Not as bad as it sounds... people actually managed to find their way around before sat nav using maps and compasses, but it is really one area the Russian military is well behind NATO and it is being addressed I would suspect as something they learned from this conflict in South Ossetia.
If Krasnopol could be GPS guided, it would of been, so far the AAR for the Excalibur is very proficient.
The guidance equipment for satellite guidance is smaller and easier to make than laser homing. The satellite receiver can be a chip the size of your fingernail... a company in New Zealand developed one and cell phone companies and electronics companies came rushing to their door. This small chip as a receiver obviously needs and antenna and a battery, but both these components are already part of the design of a cell phone so by adding a chip the size of your fingernail and some software to the existing hardware you can turn a cell phone into a simple GPS receiver.
The cellphone is less than 500 grams or half a kilo or less. In Krasnopol-M, which is a 50kg projectile there is plenty of space to add a Glonass receiver chip and antenna and a short term chemical battery in addition to the existing electronics.
The problem hasn't been an inability to do it. The problem has been that until your recon assets can provide coordinates of targets and communicate them to artillery batteries, and of course until Glonass offers decent coverage and accuracy what is the point. For all we know they might already have them ready to go into service.
Developing a module that allows laser aiming plus image recognition like SOKOL-1 (if it can see and attack tanks without a laser target marker marking the tank then it clearly has optical image recognition capabilities as well) and add satellite guidance that can be used in the Gran 120mm guided round then this guidance can also be applied to the larger calibre guided shells for 122mm, 125mm, 152mm, 203mm and 240mm tube artillery weapons.
The export potential will be limited of course to those who get to share military GLONASS signals, like India.
