Quantum Positioning System
The Global Navigation Satellite System (GNSS), has been widely used for PNT (Position, Navigation and Time) services. With availability of cost effective GNSS jammers and spoofers, the services of GNSS can be degraded/ denied. The selective availability of GNSS signals that can be exercised by the service controllers also puts a question mark on the availability of these services in times of conflict. Accurate functioning and availability of reliable signal poses a challenge for operational efficiency. In absence of positional information from GNSS, Inertial Navigation System exist that can provide Positional information for a limited period of time; however, the precision decreases due to induction of drift errors. The challenge is to design and develop a Passive Quantum Positioning System that once aligned (using GNSS), can maintain PNT accuracy for over 10 days in absence of an external GNSS inputs.
