Welcome to ESMO AOCS blog!

This is the blog of the Attitude and Orbit Control System (AOCS) teams, AOCS1, AOCS2, AIM and STAR, of the ESMO (European Student Moon Orbiter) mission. ESMO is the first ESA's (European Space Agency) Education Office project to our natural satellite.

AOCS1 team is the leading team and is responsible for main subsystem design, AOCS2 will code the on-board software, AIM will provide interface for sensors and STAR will develop and build the Star Tracker.

ESMO PDR ongoing!

Hello World! ;-)

Just a brief post directly from ESMO PDR which is being held @ ESTEC in Noordwijk, The Netherlands.

These first days we get through the RIDs closure process. RIDs (Review Item Discrepancies) are issues raised by the independent experts which are in charge to review the design, trade-offs and requirements.
RIDs process is now about to end with the last subsystems of the satellite, this morning.
Yesterday it was AOCS turn and we are glad to tell you our RIDs were closed and clarified successfully. This means that, with minor fixes and clarifications, our design was approved and we can proceed straightforward with the next phases of the project.

A very important upcoming change will be the change of the Propulsion System baseline, which proved not to comply with the strict pointing accuracy needed for thrust vector control during the manoeuvres.
We will address the new trade-off in the remaning PDR Workshop days as well as FDIR concepts.

As for now that's all from our side. We will keep you updated on future project milestones completions. Please feel free to contact us for further info and definitely for sponsorships and collaboration proposals! (aocs4esmo@gmail.com)

To the Moon!

First draft of requirements delivered

AOCS1 and AOCS2 have just completed a very first draft of the subsystem requirements document; in particular, we had to flow down subsystem, unit and software requirements. For now, we derived a few just for the AOCS itself. Of course, there will be some also for other subsystems, as our teams affect the design of many other parts .

We are sending it to SSTL for a first review. Then, with the typical trial-and-error method, following their feedback we are going to update it over and over until the final version will be ready for Preliminary Design Review.

Flowing down requirements is another thing we are learning to do with this project, because it's obviously something the University can't teach us: it isn't easy for us to do this kind of paperwork, but it's a very important part of the Space Engineer's job.

That's all for now!

Still searching for hardware...

Hi all! Here is a little update from AOCS1.

Still searching for discounted Reaction Wheels... if you have a spare Reaction Wheel you don't use in your garage, feel free to tell us! :-)
Meanwhile, we... well... I have prepared a little 3D Matlab model of the ESMO spacecraft for sensors/actuators placement tradeoff decisions. The model also simulates the angular rates caused by the activation of our 4 Attitude Control Thrusters.

Stay tuned for more...

Welcome to our blog!


This is our team's blog. ESMO (European Student Moon Orbiter) is the first ESA educational mission to our natural satellite.

We are students from Politecnico di Milano. Our mission is to design the Attitude and Orbit Control System (AOCS) for the ESMO mission! This is a very low cost mission, so any sponsorship would be very welcome!! We offer an opportunity to test experimental equipment.

Bye for now!
