Listening


To listen to SACRED if it had made orbit, a person would have needed the following:

  1. The keplerian elements, in order to know where the satellite is pointed.
  2. A radio capable of operating on 436.870 MHz, which will change with doppler shifting.
  3. A 1200 baud AFSK modem, preferably a very low-end, that does no modulation on its own. Cubesat Groundstation uses a custom-built hardware modem, and possibly a software modem (using the sound card as an Analog-to-Digital converter).
  4. The UA Cubesat GS software would help, however, it is not currently available to the public.
  5. A good antenna system, the design of the antennas is not optimal.


Components

SACRED had the following components included:
  • 6 solar cell
    Solar cell

    A solar cell or photovoltaic cell is a device that converts sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight, while the term photovoltaic cell is used when the source is unspecified....

  • Aluminum frame - built to spin-stabilize
    Spin-stabilisation

    Spin-stabilisation is the method of stabilizing a satellite by means of spin. For most satellite applications this approach has been superseded by three-axis stabilisation....
     through sunlight
  • Power board (used to hold batteries, maintain 5V and 3.3V charges, measure voltages and currents in several spots, and convert the power from the solar cells to usable power.)
  • Microcontroller board, which is used to gather and transmit telemetry.
  • Radio board, which is used for 2 way communication
  • Experiment - A radiation experiment, which will monitor the radiation effect on several components over long periods of time.


Specifications

These specifications are without respect to the payload.
  • Dimensions - 10 cm×10 cm×10 cm
  • Mass - max 1 kg (Actual ~900 gram)
  • Power Generation - Optimum ~2 W, average on sun side ~1.5 W
  • Max power output - 3W when transmitting data
  • Min power output - 100mW when in quiet state


Current status

SACRED was launched with UA's satellite, Rincon 1
Rincon 1

Rincon 1 was a Cubesat built by the Student Satellite Program of the University of Arizona. The primary payload was furnished by Rincon Research, hence the name....
 on July 26, 2006, at 19:43 UTC onboard a Dnepr rocket. The launch failed shortly after takeoff and SACRED was destroyed.
