Which is a fair assumption. GPS going civilian in the 1980s was an incredible thing, so was the lifting of selective availability two decades ago. Without American govt spoiling the market there'd be little incentive.

And people forget, the Reagan administration only made a point of ensuring future civilian access to GPS after Soviet air forces shot down a commercial airliner (KAL 007) that mistakenly wandered into their airspace. Had such an incident not occurred, it might have been kept for only military use.
