A modified version of the SGP4 code used for standard satellite orbit computation using two-line elements (TLE). The modified code outputs satellite positions and velocity in ECF coordinates and universal time from EPOCH. Utilities are provided to calculate point-to-point angle, range rates, TCS positions, constant altitude intercepts and velocities. Outputs are collected in a structure and retained in a *.mat file for subsequent display and Beacon satellite data analysis applications. Documentation and examples are provided. Code uses GPS_CoordinateXform and IGRF utilities available from MATLAB Central.
