Two points in space would not locate it at all, just like a Decca signal: you would be at some point along a line.
Also the satellite cant know where it is if it is only referencing the Earth as a point in space. It would then be moving in the universe relatively to the Earth. Even then, the allegedly straight line to the earths reference points is also an assumption based on some median of an infinite radius.
Confused? Me? Pass me another beer.

Next one would be due 30/6/07 but there will be no change this time. GPS time is ahead of TAI by 19 secs
INFORMATION ON UTC - TAI
NO positive leap second will be introduced at the end of June 2007.
The difference between Coordinated Universal Time UTC and the
International Atomic Time TAI is :
from 2006 January 1, 0h UTC, until further notice : UTC-TAI = -33 s
Leap seconds can be introduced in UTC at the end of the months of December
or June, depending on the evolution of UT1-TAI. Bulletin C is mailed every
six months, either to announce a time step in UTC, or to confirm that there
will be no time step at the next possible date.

The definition of Fred Drift:
Someone starts a post pointing out that "quick" equals "six months". It turns into a discussion where less than a nanosecond will have a material difference.
... and there I was thinking that a nanosecond was the time it took for the tosser in the car behind you to hoot once the traffic light turned green.
