This section will provide a brief overview of the development activity and system context as delineated in the following two subsections.
This document aims to provide of concept of operations for the development of an ADCS system for University of Waterloo Orbital's submission to the 6th Canadian Satellite Design Challenge (CSDC). The designed satellite is a "selfie-sat", able to communicate with amateur operators and take pictures of the ground when given the command to. The satellite is expected to operate in Low-Earth Orbit, following either a sun-synchronous or ISS orbit.
Summarize the conditions that created the need for the new system. Provide the high-level mission goals and objective of the system operation. Provide the rationale for the development of the system.
The 6th CSDC involves the design of a "selfie-sat" 3U CubeSat, allowing for amateur operators to communicate with the satellite. A need exists for the development on a reliable ADCS system to accurately maneuver the satellite, allowing for detumbling the spacecraft, pointing the camera to desired targets, and orienting the satellite for mission-critical systems to function as intended.
State the basic assumptions and constraints in the development of the concept. For example, that some technology will be matured enough by the time the system is ready to be fielded, or that the system has to be provided by a certain date in order to accomplish the mission.
In the development of the system, it is assumed all required components are readily available and easily accessible to the team. The orbit of the satellite is assumed to be in Low-Earth Orbit (LEO). The path of the orbit is not specified but is assumed to either follow that of the International Space Station (ISS) (inclination = 51.66$\degree$) or to operate in a sun-synchronous orbit (Equator Crossing Time of 10:30 $\pm$ 1 hour).
This section lists all the documents, models, standards or other material that are applicable and some or all of which will form part of the requirements of the project.
As the upcoming CSDC competition is expected to be the same as the last one (CSDC-5), previous documents are referenced for the early development of the satellite. More up to date documents are referenced as they become available. Important documents include the competition documents:
