Abstract:
Increasing international cooperation in the areas of orbital collision avoidance
and electro-magnetic interference mitigation has driven the exchange of satellite
ephemerides to support Space Situational Awareness, threat detection, and
avoidance. To be useful, ephemerides must conform to certain specifications in
order to ensure that the intended precision of these analyses is achieved. This
paper examines the accuracy of various interpolation methods as a function of
ephemeris step size and ephemeris numerical precision for a variety of orbital
regimes.
