Can Russia sell home-grown satellite navigation to a country reliant on American GPS?

With the Glonass satellite-navigation constellation nearly complete, Russia's plan to wean itself off the US Global Positioning System (GPS) appears to be coming to fruition.
But Moscow now says it wants the Russian system to work hand-in-hand with GPS rather than being a direct competitor.
A major Russian producer of navigation technology, KB Navis, also claims that it has developed the world's first revolutionary chipset capable of receiving signals from the GPS, Glonass and other navigation systems.
Why Not?
Sure why not?
This will make our receivers a lot more accurate and reliable. Then add European Galileo and it will be even better yet.
The new chip sets for GPS/GLONASS/GALILEO will make receivers we have today obsolete/dated and will be a awesome technology.

Requires Cooperation
While it would be nice, I would suggest that it won't happen.
I have no doubt the US Military isn't going to give up control of how the timing signals are controlled and sent in concert by the satellite system they use for flying unmanned vehicles and gps guided missiles.

the data for the civilian signal is public

U.S. GPS has both a civilian and (on a different frequency) a military signal. While they may not be willing to make the even-more-accurate military data availability to all countries (or even to the U.S. citizens who paid for it), they make the civilian signal available to all. The civilian signal is currently run without the extra error that was previously being injected into it (known as "selective availability"), but that extra error signal could be re-introduced if it was politically decided to do so, although growing dependence on the civilian signal by key groups such as aviation leads many to conclude that this extra hobbling of the GPS signal is unlikely to occur again.
Satellite navigation based on multiple signals is going to make it even more unlikely that selective availability will be re-enabled, since there would be little point in a war turning S.A. back on if the enemy had accesses to an alternate system.
Russian sat-nav almost complete

Russia's answer to the US Global Positioning System, Glonass, is nearing completion with almost all of its satellites in place.
Additional Accuracy

Even before SA was turned off, there was Differential GPS available to provide corrections. Also there is now WAAS. Putting SA back on might hobble older equipment, or equipment that cannot receive correction information from DGPS or WAAS, but newer equipment could probably cope. So it does get back to the issue of what would be the point in turning it back on?
I support the right to keep and arm bears.
