| dc.description.abstract | In the traditional space industry, government agencies or large defense contractors dominated the resources and accessibility to space. “New Space”, refers to the recent wave
of private companies and startups that are revolutionizing the space sector with innovative technologies and business models. New space companies focus on reducing costs,
increasing access, and leveraging modern technologies such as reusable rockets, miniaturized satellites, advanced manufacturing techniques, and seeking faster development cycles.
This has led to more and more private entities and new startups aiming to provide different kinds of services including launch services, CubeSat solutions, and other as-a-service
solutions. The easier access to space gives universities and industry a chance to develop
their space missions and also speeds up the exploration of our universe.
Kinetic Optical Yaw Observer (Koyo) is a 3U CubeSat mission developed under the
cooperation of Hex20 Inc., Aegiverse Co., Ltd., and National Central University (NCU).
There is a science payload and a service payload onboard. The science payload is a
Fiber-Optic Gyroscope (FOG) for technology demonstration and verification, as well as
to measure perturbing torque along the Low Earth Orbit (LEO). The service payload is
a Very High Frequency (VHF) transponder that provides an Automatic Packet Report
System (APRS) function to relay messages in VHF amateur radio bands.
In this thesis, an overview of the spacecraft system and a brief introduction to each
subsystem will be delivered first. The second chapter describes the mission life cycle and
koyo mission overview which elaborates the objectives and the concept of this mission.
Then introduce the payload and its data interface. The main focus of this thesis is on the
payload control software design and firmware interfaces between the On Board Computer
(OBC) and payloads. Furthermore, the payload integration with the FlatSat will also
be noted in the fifth chapter. Finally, chapter six gives the conclusion from the project
perspective and the engineering perspective, as well as the future work of the koyo mission. | en_US |
