The College of Engineering at the University of Central Florida has a flight simulator. This simulator was built as a stand-alone Instrument Flight Rules (IFR) training aid. The college has attempted on several occasions to augment this simulator system with a visual (out the cockpit view) simulation for the trainee pilot. Funding and resources have restricted or limited these enhancements to non real-time simulation. This project/thesis provides the university with part of the solution to accurate real time simulation. The simulated aircraft position and direction is acquired at 9 to 40 Hertz with 10-bit resolution. This data is made available in the ubiquitous RS-232C standard format. Thus any size computer can utilize the position and direction information for the simulated aircraft. With this element completed, a future project can utilize this information for time and motion studies or visual simulation.

A photonic analog-to-digital converter (ADC) based on a robust symmetrical number system (RSNS) was constructed and tested. The analog signal to be converted is used to amplitude modulate an optical pulse from a laser using three Mach-Zehnder interferometers (MZI). The Mach-Zehnder interferometers fold the input analog signal for a three-channel RSNS encoding. The folding waveforms are then detected and amplitude-analyzed by three separate comparator banks, the outputs of which are used to determine a digital representation of the analog signal. This design uses the RSNS preprocessing to encode the signal with the fewest number of comparators for any selected bit resolution. In addition to the efficiency of its use of comparators, the RSNS encoding has inherent Gray-code properties making it particularly attractive for eliminating any possible encoding errors. The RSNS encoding is combined with an optical infrastructure that offers high bandwidth and low insertion loss characteristics. A full implementation was constructed and tested. The lack of a high-speed data acquisition device limited the results to examining the preprocessing and digital processing separately. With the system integration of a data acquisition device, a wideband direct digital antenna architecture can be demonstrated.
