Multiple hypothesis positioning algorithm for robust GPS-denied navigation

In the past few decades, GPS has become the dominant source of precision navigation and is often required for many modern systems to operate. However, recent exposure of GPS vulnerabilities have called into question its overall resiliency and shown necessity for robust alternatives. Precision celestial navigation using Draper's Skymark technique can be used to replace GPS. However, these systems rely on prior position knowledge for system initialization. In GPS-denied scenarios, prior position knowledge may not be available or trustworthy. Similarly, other GPS-denied navigation techniques such as landmark navigation or vision-aided navigation can be difficult when there is limited prior position information. Therefore, the Multiple Hypothesis Positioning algorithm is developed in this thesis to provide robust positioning in GPS-denied navigation scenarios where little or no prior position knowledge is available.
