SINS Augmentation by ANS and Secure Radio Positioning System

Autonomous disposition of inertial measurements has rendered the strapdown inertial navigation system (SINS) the system of choice for navigation. The SINS, however, suffers from long term error growth. Significant part of the error growth rate is dependent on the inertial sensors biases and initial misalignment. In view of the unavoidable sensors imperfections, it has been established that SINS has to be periodically corrected for the errors mounted up over periods of time. Global Positioning System (GPS) is the most popular system extensively used for the purpose. Reliability of GPS dependent system is compromised because of its vulnerability to external interference. An SINS augmentation scheme comprising astronavigation system (ANS) and secure radio positioning system (SRPS) is proposed. The proposed scheme has the potential to address the issue for specific missions with enhanced level of reliability
