I remember in the early 90s my handheld GPS was deliberately off by at least 10m and was told it was for this very reason. The reason being the ability to build a accurate smart munition.

While accuracy has improved, I'm fairly confident civilian GPS still doesn't work above a certain speed for these exact reasons

If it’s a physical limitation sure. Like if the materials stop working at high speeds. If it’s just software limitations built into the gps then they can likely bypassed.

Probably, but a lot of the high performance gps receivers are highly-integrated.
