Chinese system to impact design of future U.S. GPS?

The Space Review published a fascinating article today entitled Will China compel the development of GPS 4?  Here’s a couple of snippets:

"The Chinese are going to try to do to both America’s GPS 3 and Europe’s Galileo systems what the Europeans, under French leadership, tried to do to the US. Europe originally planned to neutralize the military advantage of the US system by putting their signal on a frequency so close to the US M-code one that any attempt to jam their signal would interfere with the US system’s operation: a neat trick that was aimed at giving France a de facto veto over all US military operations…

For the US the best solution would be to limit the GPS 3 program to three or four satellites and proceed directly to a “GPS 3.5” and then to GPS 4."
