Research Focus

Stanford is widely considered by many as the world’s leading institution performing PNT and GPS research today. It all started in the early 1990’s. The early research included:

  • Use of GPS for Spacecraft Attitude and Translation Control
  • Autonomous Aircraft
  • Airplane Navigation, Takeoffs & Landings
  • Precision Farming / Agriculture
  • En-route Flight Safety
  • GPS Augmentation Systems (WAAS and LAAS

The GPS Lab was organized in the late 1990’s and sponsored research continued to evolve. In the last ~20 years the research includes:

  • WAAS and SBAS Augmentation Systems
  • Cyber Safety for Transportation including anti-spoofing & jamming
  • Alternative PNT
  • Multi-Constellation GNSS
  • GNSS Software Receiver

… and more recently:

  • Positive Train Control

Today there are over 3 billion users of GPS.  GPS, GNSS and PNT have become a de facto utility. We expect the GPS Lab research to continue to evolve as demand for accurate position location and time is desired and/or required in more-and-more applications worldwide.

The Current and Continuing GPS Research pages in this section describe the various new and ongoing research projects in the GPS lab.

The Early GPS Research pages in this section describe research projects from the formative years in the decades of 1990 and 2000.
