WebThe positions of the bodies must be computed separately for each input file time. There are three essential steps in performing this process: 1. compute SSB time (Einstein delay); 2. determine which interval, and then which sub-interval the time of interest falls in; 3. Compute Chebyshev polynomial. WebJPL uses the ephemerides for navigation of spacecraft throughout the Solar System. Typically, a new ephemeris is computed including the latest available observations of the … WebSince 1996, the Horizons system has provided searchable access to JPL ephemerides for all known solar system bodies, several dozen spacecraft, planetary system barycenters, … steel lintels in concrete block walls
