Students Design A Satellite Via Internet

      The point is not really to get it to work properly, it's to interest students in space tech.
      Space missions are a problem, because the project lifespan from first spade to launch is typically five to ten years, too long for students to have a chance to get involved without a career decision.
      These cubesats are an excellent idea, because they can hitch a ride on some commercial launch since their payload&volume are minimal.

      I agree, mostly.

      It's nice to allow students (and their professors) this opportunity, but given their very small size (10cm!) these aren't terribly useful or complex creations.

      They're more like the 'Hello, World!' version of satellites. How instructive can these things be? Perhaps the real lesson is how the distributed group worked together, rather than what they produced?

      Well being one of the students working on SSETI-Express and also on cubesats I respectfully disagree.

      The cubesat AAUSAT-IIthe we (the students at AAU AAU) are working on includes systems that are more advanced than many commercial satellites.

      The communication system utilizes a CAN-bus which is something NASA is still doing feasability studies on. The attitude determination and control system provides full three axis stabilisation and control using magnetorquers and momentum wheels for actuation and sunsensors, magnetometers and gyros for sensing. This is also a first, especially in a 10x10x10cm cube with a mass of 1 kg.
      The payload is a gamma ray burst detector from DSRI, danish space reasearch institute www.dsri.dk, which is being tested and spacequalified on this launch.

      I think you should try to figure out how you would put:
      EPS (Electrical Power System)
      - solar cells
      - batteries
      - power conditioning
      - power distribution

      ADCS (Attitude determination and control)

      - Magnetometer
      - Magnetorquers (coils)
      - Momentum wheels (motors + flywheels)
      - Various filtering, sensorfusion and control algorithms.

      OBC (On Board computer)
      - Microprocessor system
      - Command and data handling
      - Fault tolerance
      - Software upload (in orbit)

      Payload
      - Actual payload
      - + interfacing electronics

      Mechanical structure
      - Harness
      - Structure
      - Thermal analysis

      All fitted into a cubesat (10x10x10cm) max 1 kg.

    Here is what ESA says about this collective work over Internet.

    Scattered in universities across Europe, a 250-strong team of students have never collectively met in person, but between them they have built a space-ready satellite.

    Collaboration between the pan-European network of students, universities and experts involved in the Student Space Education and Technology Initiative (SSETI) has been carried out via the internet.

    Now that the completed subsystems are being delivered to ESA's European Space Technology Centre (ESTEC) in the Netherlands, remote participants from Italy to Denmark are eagerly following the integration process through daily photo updates, the integration logbook, and even a webcam.

    What is the mission of this satellite?

    Like a Russian doll, SSETI Express will carry inside it three smaller 'cubesats' -- 10-centimetre cube technology testers built respectively by universities in Germany, Japan and Norway -- for deployment when in orbit. The main SSETI Express satellite itself will test and characterise a propulsion system, return images of the Earth and serve as a transponder for amateur radio users.

    The future SSETI Express satellite Here is a drawing of the future SSETI Express satellite. (Credit: ESA) It measures only 60 by 60 by 70 centimeters and is part of the Russian mission Cosmos DMC-3. If everything goes fine, it will be launched in May 2005.

    The SSETI team is already working on another satellite, the European Student Earth Orbiter (ESEO). This one will be more complex than Express, weigh 100 kilograms, and it will be launched by an Ariane 5 rocket in 2007.

    Besides these two satellites, the ESA looks at the future.

    Coordination between groups is carried out using a dedicated news server and weekly Internet Relay Chats (IRCs) as well as the SSETI website. Face-to-face meetings are the exception rather than the rule, with group representatives meeting every six months for a workshop at ESTEC.

    Beyond Express and ESEO, SSETI has hopes of becoming a fully-fledged facilitation network for all student space activity, with members carrying out detailed feasibility studies for a European Student Moon Orbiter (ESMO) a European Student Moon Rover (ESMR) and even an orbiter for Mars.

    And here is the conclusion of Philippe Willekens of the ESA Education Department.

    "This unique opportunity for students is also a unique opportunity for ESA to see how the young generation is working through a wide internet-distributed system, with little resources, but great enthusiasm and energy."

    Good luck to all!
