About Us
For the past several years SFU Satellite Design Team has existed our goal has been to provide education and training for future engineers who are interested in the space industry. The projects we have worked on so far have provided us with extensive knowledge in space systems. Our team allows our members to reach their full potential now in undergrad to prepare them for a fulfilling career in the Aerospace sector after graduation.
Attitude Determination and Control System (ADCS)
Attitude Determination and Control System (ADCS) is in charge of the various sensors used to determine the orientation and position of the satellite, as well as re-orienting the satellite when necessary. With the many sensors onboard a satellite, the ADCS team is currently working on a sensor fusion and filtration algorithm to eliminate noise for the On Board Computer (OBC). Additionally, the team is designing and building a custom test rig for the satellite actuators, which will simultaneously test the magnetorquers and control algorithm.
Command and Data Handling (C&DH)
The Command and Data Handling team (C&DH) works hard to develop the onboard computer (OBC) for our satellites. We design custom circuit boards and create specialized firmware tailored to meet the satellite’s needs. We also handle the management of executing commands, storing data, and gathering telemetry.
Communications
The communications, or RF (Radio Frequency) team makes sure that the satellite can communicate with our ground station back on earth. This communication link will handle the downlink of satellite telemetry and payload data, as well as the uplink of telecommands.
Electrical Power System (EPS)
The EPS team oversees generation, charging, storage, and budgeting of energy in the satellite. This can go from running models using code and simulation software to researching, designing and testing printable circuit boards (PCBs). Batteries can be highly sensitive, so our job in a nutshell is to make sure the satellite does not run out of power or have any exploding parts.
Payload
Every project has a payload or reason for existing, and the payload team is in charge of building that. What we do specifically changes from project to project: Previous examples are atmospheric sensors, cameras, and calibration equipment for ground systems. For ALEASAT we are developing a centrifuge payload, which is an adapted reaction wheel. The team has already designed and manufactured a small prototype and is currently building a test rig to verify different operating modes.
Structure
The structure team is responsible for holding the satellite together under extreme conditions. The team ensures all components are securely mounted within the satellite to survive extreme temperatures and vibrations during launch. They also develop the antenna deployment systems, and perform extensive simulation analyses to ensure the satellite will survive in orbit.
SFU Aerospace
SFU Aerospace is a joint initiative among the four largest aerospace teams at Simon Fraser University to create a multidisciplinary space and diversify the future of the aerospace industry. Together, we represent over 140 students from a variety of disciplines and their ambitious goals from designing and building satellites, rockets, autonomous drones, and astronautic robotics. SFU Aerospace provides a cross-collaborative environment for the teams; spearheads technical projects outside of the team’s direct domains; represents each design team in their efforts for funding and resources; and further one of our core values of making STEM education accessible to all, regardless of background or previous experience.
