GPSSIM: Satellite Simulation for Microsoft Windows
Senior Project: 1992-1993

NAVSYS specializes in developing custom hardware and software for applications
involving the use of the Global Positioning System (GPS). GPSSIM is a satellite
simulation program which allows a user to determine the positions of satellites
for future dates. The user can use these positions to find out when satellites
will be in view to a particular area on the earth. The original program was
written in a DOS environment, using a mixture of text and graphics. The goal of
the project was to write a new interface to take advantage of the Windows NT 32
bit operating environment. Designing and implementing this new interface
entailed creating windows and menus which allow the user to input parameters,
run simulations, and analyze data. Graphic screens were used within the
simulations to depict satellite motion and user locations. Multi-tasking was
added so that simulations could be run simultaneously. The software was
implemented in the C programming language.
