As for timeline? Once the U.S. entered the war, that's when the F-15s with ASAT missiles got turned loose, and the Soviets responded with their ground-based system.

This! I've always had the debate that the GPS satellites were so important to the West that they would be protected at all costs. Even duplicate ground stations exist for GPS. I think the original developers were unaware of just how important they were to the Airforce and the Navy.
That being said, I could see CONSIDERABLE gaps forming in the GPS coverage (like a 50-50 chance of getting a signal), especially for ground units. I know that in the Allegheny National Forest today, you only have about a 75% chance of finding a GPS signal through the canopy. I can only imagine how much harder to get triangulation it would be in Twilight2000.
