RAAF M2 @ Nanosats Database

Name	RAAF M2
Type	CubeSat
Units or mass	6U (1/2 12U)
Organisation	University of New South Wales (UNSW Canberra)
Institution	University
Entity	Academic / Education
Nation	Australia
Oneliner	Deliver to the RAAF AIS / ADS-B capability across the globe using COTS AIS and ADS-B systems.
Results	Successfully commissioned several of our mostly in-house subsystems: - The attitude determination and control system (ADCS) - The software-defined radio (SDR) - The supervisor and GPS - The engineering camera In addition, we’ve deployed the first of four deployable solar arrays on each of the spacecraft using our in-house burn wire mechanisms. The graphs below show the power generated by the solar cells before and after exposure to sunlight (top), and the dynamic response of the spacecraft due to the impulse of the deployment recorded by the ADCS sensors (bottom) for M2-B. Operations for the coming weeks will be focused on rehearsing for the much awaited controlled separation, aka "divorce", of the two spacecraft! In May 2021, successfully performed on-board [artificialintelligence](https://www.linkedin.com/feed/hashtag/?keywords=artificialintelligence&highlightedUpdateUrns=urn%3Ali%3Aactivity%3A6805732956343275520) inferencing (correctly recognising hand-written characters on pre-loaded images), to test the functionality of the AI environment and pipeline using the [NVIDIA](https://www.linkedin.com/company/nvidia/) Jetson TX2 edge-computer on one of the two M2 satellites. This is a necessary step before separating the two spacecraft from each other (currently joined, see the image) and, as the mission unfolds, coupling our AI algorithms and on-board sensors to perform tasks such as cloud detection and maritime surveillance. In September 2021, the spacecraft were separated.
