Chapter 5, A Software Receiver


By Scott Gleason, Morgan Quigley and Pieter Abbeel

A fully functional software receiver has been designed to demonstrate many of the steps performed in a GNSS navigation receiver, as overviewed in Chapters 2,3 and 4. This receiver includes: a FFT acquisition; code and carrier tracking; pseudorange measurements; navigation data decoding; and position, velocity, and time estimation functions. The software receiver is also capable of using external aiding data from the International GNSS Service (IGS) as well as applying WAAS differential ionosphere corrections.
