Satellite and GPS role

[PK_Patriot]

What is satellite and GPS role in situation of war? GPS is american technology and how much US has control over it (US can stop any time, start anytime, deceive any time with wrong information) ?

I think US has ability to stop GPS system during war and GPS coordinates are very important for targets as they precisely defines where to hit. Cruise missiles and other strategic missiles use this technology. If US stop them for a region what to do with these missiles tech ?

Yea cruise missiles uses GPS system. Russian have their own system of positioning system. Chinese don't have any if I remember correctly ! Difficult situation for Pakistan!

It is enough for Pakistan to target INDIA

but problem is how much big area these few satellite can cover ,,,,,,,,,,,, US would have 100s of those satellites if not in 1000s

Stick to topic and don't get personal...It is known that Chinese do not release entire information regarding how they use satellites. I do not want to get into details about their ever new coming out ICBMs large number of current ICBMs and MIRV and other weapons that would require the used of Beidou...They do not share the specifics and entire information on usage however you may draw any conclusion.

By the way informative Article not entirely accurate.

The US owns the "GPS" system and there are competing systems being put into place by various countries (GLONASS, BeiDou, etc). The US reserves the right to manipulate this system during wartime.

However the US is looking into backup technologies in case the satellites are not available.
