Web— Spacecraft tracking files. These are the standard doppler and range data which are used by the JPL Navigation Team for determining spacecraft trajectories. If the spacecraft is close enough to the planet to be influenced by its gravity, the ephemeris of the target planet is adjusted as part of the orbit determination process. WebThere's a related question, but it doesn't seem to apply to spacecraft trajectories.. Suppose you want to send a non-thrusting spacecraft far from earth, and you have ground tracking of the spacecraft, but the spacecraft doesn't have any way of directly incorporating position/velocity updates into its nav system (no GPS, for example).
