In April 2020, I presented a talk on understanding GPS in contested environments. Topics included the following:

    • Understanding GPS position error
    • Dilution of precision and user range errors
    • Physical and radio visibility
    • Terrain heights and field results
    • Mitigation techniques
    • Alternative navigation technologies

I presented this talk again at the AUVSI XPONENTIAL conference, on October 8, 2020. The presentation below is slightly updated, and is from this later presentation.

The full paper is available here: Paper: Understanding GPS in Contested Environments
