  1. Maybe that is why Russia has conducted an anti satellite missile test. It maybe a precursor to disabling, either western battlefields surveillance satellites or the GPS systems on which military drones and other smart weapons depend. Blowing up a satellite is such a test is extremely dangerous, as the resulting debris could trigger a cascade of destruction of other earth orbiting space hardware. The so called Kessler effect. Such an event could trap humans on earth, in a super high velocity metal cage of their own making, bringing space exploration to an end, along with satellite earth observations. China has, in the past, conducted similar dangerous tests. It would not be surprising if Russia had developed an alternative navigation system to the generic GPS system.
