Yes, there is a DOS-program. But you need some codes from CMC/Novatel to
unlock extra features you want.

If the unlock codes are still for purchase, that would obviously be
cheaper by most peoples standards, than building from scratch.

There used to be other receivers based on the now obsolete Zarlink
chipset. Signav and GPS Creations comes to mind.
