European Students to Put Microsatellite Into Orbit 117

Posted by samzenpus from the easy-school-project dept.
Astervitude writes "A Frankenstein's microsatellite made out of parts "donated" by university students across Europe will be launched on September 30 atop a Russian booster. Space.com reports that more than 400 students "spread across 23 universities and 12 countries" spent 18 months designing and building the SSETI Express. While its acronym sounds suspiciously similar to that of a project that seeks to uncover signs of intelligent life beyond Earth, the SSETI or Student Space Exploration Technology Initiative mission is actually part of an effort by the European Space Agency "to boost student interest in space technology and offer some hands-on experience." The satellite itself weighs a mere 136 pounds and is the "size of a small washing machine", as shown in this ESA photo. Visitors to the mission site may want to check out the contest page for ham radio operators to help collect data from the satellite."

    From the SSETI Express [tuwien.ac.at] page:

    Payload systems:

    The Attitude Control and Determination System controls the attitude of the spacecraft using a pair of magnetorquers and a passive magnet and determines the attitude of the spacecraft using a magnetometer and a pair of sun-sensors.

    The camera uses CMOS technology and is capable of taking full colour pictures in the visual range at a ground resolution of about 100m per pixel, with an image size of 1280x1024 pixels. It will be used to take images of the Earth.

    The S-Band unit is the secondary communications system. It contains a microwave transmitter and TNC and is capable of 38400bps data downlink, or transponding audio from UHF via three patch antennas (S-Band ANT), acting as a voice repeater for radio amateurs.

    T-PODS - These three pods contain the three Cubesat passengers during the launch and coasting phases. After injection they will act as launcher tubes, ejecting the Cubesats from SSETI Express so that they can pursue their own missions.

    SSETI Express will carry three small nano-satellites into orbit as passengers. These will be ejected from SSETI Express shortly after the launch, and will then undergo their own, separate, missions.
    The three cubesats are:

    NCUBE-2 -Developed by the Andøya Rocket Range, Norway. This Cubesat will track boats around the Norwegian coastline (and one reindeer on land).
    [I, for one, welcome our new reindeer-tracking overlords!]

    UWE-1 - Developed by the University of Würzburg, Germany. This Cubesat will test new communications protocols.

    XI-V Developed by the University of Tokyo, Japan. This Cubesat will test commercial off-the-shelf technology and has a camera to take pictures of the Earth.

    SSETI Express has two 'radios' on-board.

    On UHF 437.250MHz there is a FM transceiver that can transmit and receive the AX25 packet telemetry and payload data at the data rate of 9k6bps. The transceiver produces approx 3 watts of RF output that feeds a canted 1/4 wave whip, which is mounted on the top plate. It incorporates a standard TNC7-Multi to convert the data to and from the OBC. It also has an audio and RSSI feed to the S-Band Tx. It was constructed by Holger Eckardt DF2FQ and is based upon his T7F UHF packet transceiver.

    Communications - On S-Band there is a transmitter on 2401.835MHz which can transmit packet data at a data rate of 38k4bps. It can also be configured to work in a voice transponder configuration. It produces approximately 2.5 watts of RF output which feed a three way splitter to the three patch antennas. The enclosure, power splitter and antennas were provided by the University of Wroclaw SSETI team and the electronics were produced by five members of AMSAT-UK. The unit comprises of a switch mode power supply, exciter board, amplifier board, controller board and a sensor board. The TNC is identical to the TNC7 Multi being used in the UHF transceiver except that it is set for a different baud rate.

    Typical Groundstation:

    To receive data from SSETI Express the requirements are similar to those for previous 9k6 Pacsats.

    To receive UHF telemetry, a steerable circularly polarised yagi with 12dBic gain with, preferably, a masthead preamplifier, should be satisfactory for reception of the data . The receiver must have an IF bandwidth of at least 20kHz and an audio output that is taken from the discriminator before any 'shaping'. This audio is then fed into a suitable KISS-enabled TNC which itself is connected to a PC normally via a serial port. To transmit to the satellite (when 'friendly telecommands' have been enabled) an RF output power of 10 watts on UHF should be sufficient.

    To receive S-Band data, the antenna gain will need to be more than 21dBic and in this case RHCP (right hand circular polarisation) is a must. Again a mast mounted preamplifier will be required. As the data rate is 38k4bps the IF bandwidth will need to be approx 80kHz together with a K

      I would not call Europe communist in general. Granted, we *are* more to the left - way more - than the US. But the fundamental difference is that we *do* have ownership rights, can start private companies, and there is a free market.

      However, we do have more things that are deemed to be the responsibility of the society. Things like education. Things like health service. Things that everyone generally need.

      I think this is a good thing. It (tries to) give everyone equal opportunity, regardless if they come from a rich or a poor family. Of course, it's not absolute, there are still private health service, there's private schools. But the general idea is that there are some fundamental rights people have, that the government should provide.

    It's not quite orbit (yet), but JP Aerospace has been running a PongSat program [jpaerospace.com] for the past few years which does something similar. Some of their past missions have gone above 100,000 feet, and would make great science fair projects for students. The description from their page:

    A PongSat is an experiment that fits inside of a ping pong ball.

    These ping pong ball 'satellites' are flown to the edge of space by balloon or launched in sounding rockets. The PongSats are then returned to the student.

    It's an easy and inexpensive way to get students excited about science and engineering.

    There are endless possibilities for experiments that can fit inside a ping pong ball. PongSat's can be as simple or complex as you want them to be. Experiments can be as simple as comparing how high a ball bounces before and after being exposed to vacuum. The PongSat can carry seeds to see if exposure to cosmic rays effect their growth. Several small inexpensive computers and other electronics can fit inside a PongSat. These can be used to create a wide range of experiments. Whether carrying a marshmallow to see if it puffs up in the vacuum of near space or an entire sophisticated satellite in miniature, PongSat can create motivation, drive
    and passion in the classroom.

    PongSats are flown at no cost to the student or school.

    I really hate to sound like a party pooper, but can we save space for those doing actual science? Space junk is prevalent enough, and competition for orbit space [esa.int] tight enough without adding more useless stuff to the mix. I mean, the most scientific items in the list of tasks are:
    -A camera with a 100m per pixel resolution (ridiculously low res, plenty of other picture taking sats available).
    -A Cubesat that will track boats around the Norwegian coastline, and one reindeer (just one reindeer? And can't we track boats with other means?)
    - A Cubesat testing new communications protocols (why can't this be done terrestrially or with equipment on the ISS?).
    - Another Cubesat that takes pictures and tests some gear (send it to the ISS).

    So, we've got 4 satellites up there, doing tasks which we can do via other means, wasting space. Why not send the equipment to the ISS? We did put it up there for a reason, didn't we?

It was put off by the Challenger explosion. It launched in the early 1990s. Nice to see European Universities catching up to the US Boy Scouts 13 years later (They launched theirs for $10,000 USD).

    I wonder how come the ESA doesn't launch things like this. Russia that hungry for business maybe?

      Russians are much cheaper, but the ESA still owns half the world market because it is more likely to deliver the payload unharmed and in the right orbit. Still ESA itself also sends up payloads on Russian rockets for reasons of economy. Apparently they decided that this payload is not valuable enough to pay for a trip on an Ariane. The students can always build another one.

    Please change title to "Russians put Europeon student's satellite in orbit."

    A bunch of students building a satellite is kinda neat, but far short of the neatness of actually putting it in orbit.
  • ...welcome our SSETI satellite overlords.
  • I first read the title as "European Students Put Microsoft Into Orbit" and got excited...

    ohwell...

  • Even high schools have sent up mini satellites.
  • ...Intelligent Design, and how abstinence is the way to success. But don't worry all these European students they will end up in American universities anyway, because you see the high NSF science budget can afford to attract...wait...no? It got reduced over the years?...well anyway the easy VISA and immigration laws will allow those students to unfold...wait...no?...there is a VISA/SEVIS hell right now...huh??

    Right, so as I was saying we don't want these liberal scum in our God fearing great country, ble
  • When I was an engineering student at Weber State University in the mid 80's we designed, developed, and built NUSAT for the FAA to monitor radar coverage patterns. The project was successful and we went on to do a couple more.
    It involved our Electrical Engineering, Computer Science, and Mechanical Engineering departments in a multidisciplinary development team.
    Been there - done it. I guess their claim to fame is they built it with scraps and donations...
