Attila,
Thank you very much for the references.  I had come across [4] when 
searching on Kalman filters for GPS aiding of INS measurements.  I 
didn't pay much attention to the GPS chapter at the time but I'll look 
at it again.  I just downloaded [3] and it appears to have a good mix of 
practical vs. theoretical aspects. I appreciate the help!
