2022-2023 Satellite Design Competition: Nanosatellites
Space Sustainability is a topic that has often been neglected throughout the decades of space development. This meant that defunct satellites were simply left to drift in space until they eventually fell back to Earth. However, this may take centuries. The 1958 Vanguard probe is expected to remain in orbit for 240 years, for example. Because of these concerns, much effort has gone into cataloging the number of debris objects in geostationary (GEO) and low-earth (LEO) orbits.
The 2022-2023 Satellite Design Competition invites students to design, construct and operate a nanosatellite payload system with the aim of developing a detection system for identifying piece(s) of space debris. Students shall create a payload concept, trade off performance parameters and pass through a rigorous review process with panels of experts within the space industry. The competition aims to reach out to students from multiple scientific fields, including, but not limited to, aerospace engineers, computer science engineers, electrical engineers, mechanical engineers and physicists.
The competition aims to:
- Challenge students to perform a complex, systems engineering task for the development of a payload to meet a set of real space mission requirements
- Gain exposure and experience of the typical design processes and protocols in industry projects, including multiple project reviews
- Enable students to apply taught technical skills and learn new ones relevant to a job in the space industry in an applicable project environment
- Provide students with an opportunity to develop and practice other important and transferable skills, such as teamwork, leadership and project management
- Provide students with support and advice from leading industry experts
Project Specifications
The challenge of this year’s competition was to design a 3U CubeSat that can detect and conduct in-situ testing on space debris that are millimeters in size. The aim of these tests was to gather any data that may prove relevant to spacecraft operators. The competition is separated into two main phases: a research & design phase and a build & test phase. Teams had to submit a Preliminary Design Review, followed by a Critical Design Review.
Mystery Room
The mystery room is a challenge on a final competition day that is set to teams in order to test the functionality of their CubeSat design. The exact setup on the day is left relatively unknown in order to keep it as challenging as possible, although requirements are set and given to the teams.
The mystery room will consist of two components: an attempt to complete the objectives inside a mystery room and a 10-15 minute presentation. Teams will be tested inside a mystery room that shall simulate the different phases of the mission, from pre-launch to end of life. The objectives will be split into three parts, which are as follows:
- Pre-launch
This will involve a structural testing of the CubeSat to determine if it is able to survive the launch load. This will be done in the form of vibration testing. - In-orbit state of health check of subsystems
These tests will check whether the subsystems of the CubeSat are operational ‘post-launch.’ It will involve testing of the TT&C system, and that data is able to be sent to and from the CubeSat remotely. It will also check the CubeSat’s power subsystem and confirm that any components that draw current are operational. A separate AOCS test will be included in the TRR submission, as there is unlikely to be enough time on the competition day to conduct this test. This is an optional test but additional marks will be awarded during the TRR stage for successful demonstration of an AOCS subsystem. - Science experimentation
These tests will focus on the main aim of the mission: the scientific data collection. This will be done through two tests:- Track the rate of debris objects passing in the vicinity of the cubesat.
- Determine characteristics of the debris, such as size, the number of pieces and anything else relevant that could be determined such as the rate of rotation. This will mimic the scientific experimentations that would be done on the debris in a real mission, but is simplified in scope.
