Webinar Presentation Slides

Inertial sensors and GNSS make for a powerful combination when supporting life-critical navigation systems, including aviation navigation and flight control.

In this 90-minute webinar, viewers heard from Alex Stratton, a principal engineer and technical project manager for Rockwell Collins, and Chuck Bye, senior engineering fellow at Honeywell Aerospace. Demoz Gebre-Egziabher, associate professor of Aerospace Engineering and Mechanics at University of Minnesota-Twin Cities, moderated the event.

Discussion topics included the following:

  • GNSS and integrated avionics typical design configurations
  •  Types and sources of inertial sensor errors
  • Modeling inertial sensor errors
  • Creating error budgets
  • Typical navigation avionics performance requirements
  • GNSS signal characteristics to simulate (clock and ephemeris, atmospheric propagation, etc.)
  • Categories of avionics testing

CAST Navigation sponsored the web seminar.
