The UTDFFile object provides functionalities for reading GroundStation Observation data (azimuth, elevation, range, range rate) from 75-byte binary files written in the Universal Tracking Data Format (UTDF). The time system is UTC, and the angle data is given as azimuth and elevation in GS Local coordinates.


UTDF, BRTS UTDF, and TDRS UTDF are binary 75 byte formats described in detail in the GSFC document "Tracking And Acquisition Handbook For The Spaceflight Tracking And Data Network", October 1994.
