Abstract : Setting up and solving ballistic type rocket kinetic equations in inertial coordinate systems with directions which do not vary, it is possible not to consider dragging inertial or centrifugal forces or coriolis inertial forces and set up inertial guidance on a convenient and simple, quick and clear foundation. This is different from what has been published in the past, where studies have been done of various types of flight mechanics problems in coordinate systems which turn, following along with the earth. We illucidate the initial take off conditions as rockets leave the surface of the earth, and analyze, in detail, the air or atmospheric effects associated with air being pulled along by the gravity of the earth as it turns and the treatment methods for aerodynamic forces on rockets moving in an inertial space. We derive a formula for calculating the geographical location of movement parameters, used for rockets in inertial coordinate systems, and a formula for dynamic coordinate system movement parameters.
