Space and time reference systems
Abstract
Coordinate systems used to represent satellite position measurements are examined and transformations into inertial reference systems which are used in the integration of the equations of motion for a satellite in order to determine its trajectory, are shown. Reference systems common to space geodesy are emphasized. The determination of ground station position as a corollary to satellite trajectory analysis is discussed. Problems of time scale which arise with comparison of nonsimultaneous measurements of different points on the globe as well as with time dependent analysis of certain kinematic and dynamic phenomena are also covered.
