This thesis presents a case study of teleoperation of the Thaw Telescope of the
Allegheny Observatory, University of Pittsburgh. This telescope is a forerunner
of the Astrometric Telescope Facility (ATF) on board of NASA's Space Station
which is set to be launched in the 1990's. A simulated model is built to
emulate the functional operations of the Thaw telescope and attached scientific
instrument. The OASIS software system is used to communicate with the
simulation model. This simulation model, written in Ada, consists of three
major parts. The Command_Receiver and the Data_Transmitter are
software written to service the incoming telecommands and outgoing telemetry,
the Command_Processor is the actual simulator itself consisting of a
Command_Retriever, a Scanner, a Parser, a
Command_Interpreter, and the actual Thaw telescope simulation.
