Trajectory sensor system functional descriptions and preprocessing
Abstract
The trajectory sensor systems measure the various propagation characteristics of electromagnetic or optical signals transmitted between the satellite and tracking stations (or other reference sources). These data are subsequently used to determine the satellite trajectory. The dependence of these measurements upon the relative states of the spacecraft provides the key to the orbit determination process. Provided is a brief functional description of the trajectory sensing systems currently included in GTDS. Also described are the procedures followed in preprocessing the data prior to GTDS processing. These computations are independent of GTDS and are presented primarily for informational purposes.
