Military platforms and personnel rely on Global Positioning System (GPS) for precision navigation and targeting, to enhance situational awareness, improve command and mission effectiveness, and to operate more safely. However, Global Navigation Satellite System (GNSS including GPS and other similar systems such as Galileo, GLONASS) rely on very low-powered signals susceptible to threats from jamming (where the signal is entirely denied) and spoofing (where signals may be generated that lead the platforms and end users to believe they are located in a position other than where they are actually located). GNSS positioning signals can also experience natural errors or denial in dense urban areas, in triple canopy, within buildings, and underground and accuracy can vary based on satellite geometry, atmospheric conditions, and more. A Universal Navigation Manager is proposed which allows real-time plug and play of new sensor types to enhance assurance (integrity, accuracy), provides redundant integrity monitoring, increasing assured position availability, reliability, and accuracy and lowers the time, complexity, and cost for integration of new navigation sensors.
