So how can Turkey assure that its ANKA or other armed drone (unmanned combat aerial vehicle, UCAV) would be independent from the U.S. GPS satellite's (or Russian Glonass, or European Galileo, or Chinese Baidu), as well as have its own missiles and/or bombs, which would also be independent from the above positioning system(s)? Would it rely on terrestrial GPS - but isn't that as vulnerable as satellite GPS, and not as effective in the mountains? What can Turkey, or Pakistan (with its Shahpur, Nescom Burraq) do to assure independence from GPS and Western air-to-surface and air-to-air missiles that the UCAV's are armed with?
