Formation of Inertial Kinematic Parameters for Simulation of Terrain Navigation Systems Aided with Geospatial Data

The paper presents аn approach to forming kinematic parameters measured by navigation sensors (coordinates, linear velocities and accelerations, orientation angles and angular rates) for simulation of the navigation system of a terrain object moving along a given spatial trajectory. The object`s trajectory is pre-represented analytically by orthogonal polynomials or step functions, after which the inverse problem of dynamics is solved. The conditions for achieving the accordance of a given route of a terrain object and the trajectory obtained by dead-reckoning algorithms are considered.
