AN INTEGRATED DESIGN ENVIRONMENT FOR SMALL
SATELLITES



SUNIL GAVINI


ABSTRACT
Small satellites are generally spacecraft weighing around few hundred kilograms
that are confined mostly to low Earth orbit where they perform specific tasks such as
remote sensing, conduct science operations, and serve as technology test beds and
communication relays. This ultimately results in a multibillion industry. Hence the design
of these small satellites plays an important role in developing a satellite. The following
thesis discusses an Integrated Design Environment for satellite design that integrates the
software required for the satellite design onto a single platform.
Software that is used for project management, requirements management and
electrical/power simulations are integrated using Visual Basic.Net. This allows the
developer to access the software from a single interface, reducing access time and
providing file sharing over the network.
