This half-day course focuses on the lower level signal processing operations that take place within the GNSS receiver and illustrates those concepts using actual raw RF GPS collected data. The course begins with an overview of the traditional GPS receiver front end and goes into detail on the GNSS signal acquisition/processing - how does it work in theory and what is the receiver doing? It also discusses the code and carrier tracking loops along with navigation data processing. The focus is on applied as opposed to theoretical operation and provides GPS examples where applicable.

The Software Radio Concept
• What is a software radio and how does this apply to GNSS receivers?
• Traditional GPS receiver front-end design
• Collecting raw GPS RF data

GPS Signal Processing I
• What happens when the receiver is first powered on
• Acquisition of the GPS signal and AD conversion
• The process of providing a position rapidly

GPS Signal Processing II
• Tracking the GPS signal; how and why the receiver needs to 
   maintain lock on the C/A-code and carrier frequency
• Navigation data processing - what data is being broadcast from the 
   satellite and how is it extracted and used?

Level: For those with background in GNSS and/or spread spectrum signal processing, and who want to understand the lower level processing that is taking place within the GNSS receiver.
