Abstract
Discussed and analyzed is a marine navigation system in which a high performance system, the Ships Inertial Navigation System (SINS), is monitored by an even more accurate system now under development, the Electrostatically Supported Gyro Navigator (ESGN). An advantage of this monitor configuration is a potentially substantial improvement in navigational accuracy, while imposing a minimal change to the existing system. General equations for performing a covariance error analysis of the SINS, ESGN, and ESG Monitor/SINS systems are described. Results are presented which draw relative accuracy comparisons between these systems.
