Probabilistic Map Matching for Robust Inertial Navigation Aiding
Navigation, 2023 Robust aiding of inertial navigation systems in GNSS-denied environments is critical for the removal of accumulated navigation error caused by the drift and bias inherent in inertial sensors. One way to perform such an aiding uses matching of geophysical

Autonomous Lunar L1 Halo Orbit Navigation Using Optical Measurements to a Lunar Landmark
Navigation, 2023 Autonomous cislunar spacecraft navigation is critical to mission success as communication to ground stations and access to global positioning system (GPS) signals could be lost. However, if the satellite has a camera of sufficient quality, geometric line-

PRN Sequence Estimation with a Self-Calibrating 40-Element Antenna Array
Navigation, 2023 This work explores the use of a low-cost global navigation satellite system (GNSS) antenna array including front-ends and a global navigation satellite system (GNSS) software receiver to receive signals of opportunity (SoO) whose pseudorandom noise (PRN)
