DEVELOPMENT OF A STRAPDOWN INERTIAL NAVIGATION SYSTEM SIMULATION PLATFORM

Abstract

This paper presents a strapdown inertial navigation system (SINS) simulation platform. The numerical simulator solves the navigation equations in navigation frame where the quaternion vector is employed for attitude calculation. The measured quantities (angular body rates and specific force) are generated by the numerical simulator. The results are also confirmed with the navigation solutions given by a commercial inertial navigation system toolbox using the generated body angular rates and specific force of the SINS. The paper can provide the readers with further information for developing their own SINS simulation tools.
