The nominal accuracy is no better than using the sun as a compass.
Two GPS systems (say TBolts) have to be an amazingly great distance
apart to give a decent azimuth.
Apart from star observations, a gyrocompass is the tool of choice if
you want to add an azimuth to a GPS position.
Does anyone know how laser gyroscopes are developing?

As a fair percentage of the discussion amongst the learned

to ask a non-time related, but GPS-related question.
As part of microwave radio experimentation, often on windy
hilltops, I have a need to find direction very accurately. I have
seen advertised GPS-based Azimuth Pointing Systems such as this:
http://www.ascscientific.com/APS.html
However they are a little (lot) out of my budget range.
The system seems to work by taking the raw satellite phase
information from two separate GPS systems and crunching the data to
come up with an azimuth figure. Has anyone heard of a (Open
Source?) program that could be used to do these calculations?
