Last years' Computer Networking Conference included a presentation on building
a GPS receiver. It included system diagrams and some details of the maths required
(though no actual listings - the radio side is covered more completely than
the processor side).

Copies of the CNC proceedings can be obtained from the American Radio Relay
League, in Newington, Connecticut. 1990 was the 9th CNC.
