Here’s a list of information I’ve stumbled across while trying to come up to speed on precision GPS.  I’ve made no attempt to make it a comprehensive list, just things I’ve found particularly interesting or useful.

I started my journey into the world of GPS by taking the Stanford online course and reading the Misra/Eng book used in the course.  I found both to be extremely informative and well done and would highly recommend both of them to anyone interested in the subject.

GPS:Signals, Measurements, and Performance (Misra/Eng):
