HackSat1 is a KickSat sprite and is due to launch some time in early 2013.

The dev kit is due May 2012. Speak to Flux if you're interested in getting involved.

First Steps

  • Get some MSP430 experience. Several people in the space have mentioned having boards.
    • We have at least 3 MSP430 devkits in the space, The toolchain is a bit icky tho, but I think we have enough incentive to fix that now.
  • Run some MSP430 workshops
  • Get MSP430 book (already bought - should be in the space shortly)
  • MSP430 Mac Howto

The Hardware

We don't get to design the hardware on this mission, just program it.

  • controller: CC430F6137 (16-Bit Ultra-Low-Power MCU, 32KB Flash, 4KB RAM, CC1101 Radio, AES-128, 12Bit ADC, USCI, LCD driver)
  • sensors: temperature + one other TBC (KickSat are taking suggestions)
  • radio: we can transmit what and when we like (subject to solar power) but data rate is only a few bits per second

"For sensors, basically they have to be packaged in a tiny SMT chip and not use too much power (no more than a few mW). We don't have a list yet, but one example of something that would work is this magnetometer: http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Sensors/Magneto/HMC5883L-FDS.pdf"

The Orbit

"While we don't know the orbit, we're aiming for a circular low altitude LEO - around 300 km. altitude. That would mean a roughly 90 minute orbit with several daylight passes per day (usually 3 or 4 over any given location). Each pass would be somewhere around 5 minutes long."

Payload

See the payload page for ideas.

Ground Station
