Incidently Oscar,nirbhay was designed by ADE bangalore,it is perhaps the first missile to be designed outside hyderbad and in bangaore(the patent capital of India).Now ADE is the lab solely responsible for develpoing un-manned aerial vehicles,their guidance and control and so on.While there have been instances that newly designed tactical prahar/pragati missile was left unattended at seol seaport(thankfully the missile was a dummy) however i dont think a HD filled with development codes,various algorithms will be left attended and casually the way you just pointed out.
As for the gyros,i can probably post couple of interviews and research documents(available in public domain) regarding the FOG and RLG that have been designed at RCI hyderabad and used in almost all of the missiles.
I was merely trying to discuss on the aspect of "HOW" will certain technological constraints be achieved by Pakistan given the lack of research and industrial maturity.And future development prospects.
On a lighter note,today hon'ble defence minister was grilled in indian parliament regarding the funding of DRDO and he briefed the parliament(in a written reply) that the yearly budget of DRDO this year will be $3.1-$3.5bn. It is sometimes frustrating when you cant simply obtain information(public domain) regarding various aspects of pakistani labs or system(like the way you'd normally get in india).A lot of civilian mechanism and bureaucratic procedures that we take for granted in india simply do not exist in pakistan!
