GPS Receiver Performance Using Inertial-Aided Carrier Tracking Loop

  title={GPS Receiver Performance Using Inertial-Aided Carrier Tracking Loop},
  author={Tsung-Yu Chiou},
Radio frequency interference (RFI) has been a perplexing problem, affecting the navigation quality of the Global Positioning System (GPS). The presence of the RFI, or even hostile jamming, will reduce the effective received signal power, and thus degrade navigation accuracy, continuity, and integrity of the system. A proposed next generation aircraft navigation system for the U.S. military called the Joint Precision Approach and Landing System (JPALS) [1, 2] is an example of a system that… Expand
