# Overview [ESA is having a competition to have code run on OPS-SAT](https://ideas.esa.int/servlet/hype/IMT?documentTableId=45087640620538411&userAction=Browse&templateName=&documentId=44b778b1fd71bbce5e75cee6bde9da8b). I think Polaris should submit a proposal. Proposals are due by May 23, 2021. I'm happy to help organize this. # What's OPS-SAT? - 3U cubesat currently in orbit, operated by ESA - Computer hardware: 512MB RAM, 800MHz CPU - Computer software: Linux OS, Python 3.5, Tensorflow Lite, Java - Other hardware: - high definition camera (RGGB Bayer colour filter, 2048 x 1944 pixels) - fine attitude control unit equipped with reaction wheels - star tracker, gyros and magnets, - software defined radio capable of sensing the RF spectrum in the UHF range (425 MHz centre frequency) - GPS receiver. More details can be found [on the competition page](https://ideas.esa.int/servlet/hype/IMT?documentTableId=45087640620538411&userAction=Browse&templateName=&documentId=44b778b1fd71bbce5e75cee6bde9da8b); a very detailed spec document is [here](https://ideas.esa.int/apps/IMT/UploadedFiles/00/f_d4aa96ccd0c7141ac4d10e072fb44d38/OPSSAT-SYS-PAY-ExperimenterICD_v0.5.pdf?v=1616565313). # What do we want it to do? Looking for proposals! Some ideas: - Use BETSI to detect anomalies in real time - Train models using SatNOGS ground stations, run them on OPS-SAT - Running ML training on the onboard FPGA # When is it due? **Soon: Proposals are due May 22, 2021.** The competition closes on July 4, 2021. # What do I need to do? These are the open questions: - Do we have time to create a submission? (Note: we may be able to get help with this from the Libre Space Foundation.) - If you have the time to help, leave a reply here. - Do we have/can we come up with good ideas for what to run on OPS-SAT? - If you have an idea, leave a reply here. # Where can I read more?

Description of NanoSat MO Framework: "This is a set of Java libraries which effectively hide the low level complication of operating the different units to allow the experimenters to concentrate on their applications – it is just like developing a smartphone app, except your app runs onboard a flying satellite. Another advantage of using the NMF is that the users can easily control these apps via a browser application over the internet." - [OPS-SAT Smartcam](https://github.com/georgeslabreche/opssat-smartcam), an application already running on OPS-SAT which classifies images taken by onboard cameras; this is used to prioritize pictures for download.
