Inertial navigation is a self-contained navigation technique in which measurements provided by accelerom-eters and gyroscopes are used to track the position and orientation of an object relative to a known starting point, orientation and velocity. The performance of hybrid navigation systems for commercial transoceanic flights is evaluated by means of a digital computer simulation of AIRNAV (Aided-Inertial Reference NAVigation), which requires the numerical integration of up to 585 first-order differential equations to propagate the covariance matrix. As the name implies, the fundamental principle involved is the property of inertia May 13, 2016 · Inertial Navigation Systems (INSs) are modern, technologically sophisticated implementations of the age‐old concept of dead reckoning. the physical and mathematical principles forming the basis for inertial navigation. which describe the motion of a particle in an inertial frame of reference.
