DESCRIPTION;LANGUAGE=en-US:Title: Robust Positioning\, Navigation and Timin
g (PNT) Systems\nAbstract\nPositioning\, navigation\, and timing (PNT) sys
tems play increasingly vital roles in our daily lives. Safety-of-life appl
ications such as aviation require robust PNT systems that are designed and
tested to ensure protection against potential error sources. In this talk
\, two common error sources are discussed. First\, the effects of gravity
model errors within an inertial navigation system are characterized. Examp
les are given demonstrating the impacts of severe gravity environments on
an aircraft navigation system. A novel testing framework is presented that
is intended to aid system designers and integrators in proving compliance
to gravity model requirements in certification standards such as DO-384.
A second error source to be discussed is GPS signal faults. Traditionally\
, GPS-based navigation systems provide integrity against unintentional sig
nal faults such as an atomic clock failure within the satellite. Recent ev
ents have highlighted the need to protect against intentional GPS interfer
ence such as jamming and spoofing. A brief overview of present and future
trends in integrity and GPS interference detection and mitigation will be
discussed.\n\n\nBiography\nTim Needham has over 20 years of experience in
academia and industry working with various aspects of Positioning\, Naviga
tion\, and Timing (PNT) systems. Currently\, he is a staff engineer at Nor
throp Grumman where he focuses on PNT system design and integrity. Tim’s
Ph.D. research focused on investigating the integrity aspects of gravity
modeling errors on GNSS-aided inertial navigation systems used in civil av
iation. He received the 2022 William E. Jackson award for his dissertation
. Previously\, Tim has worked with high-accuracy GPS systems\, instrument
landing systems\, and sense and avoid technologies. In addition\, he serve
d on RTCA SC-159 Working Group 2C (WG2C) and coauthored DO-384 Appendix O.
Tim received a B.S.\, M.S.\, and Ph.D. in electrical engineering from Ohi
o University in 2003\, 2008\, and 2022\, respectively.\n\n________________
