I can place the antenna on ashort mast on rooftop with clear 360 degree view of the sky. The antenna location is about as good as it gets. I've downloaded and read some of the GPS user manuals. The new ones are 12 channel and older ones are 5 or 8. I guess with a surveyed location you could get time from just one satellite. But you'd need more if you wanted to take account of the atmosphere. I don't know if receivers do this.
