SACRED was a Cubesat built by the Student Satellite Program of the University of Arizona. A CubeSat is a type of space research picosatellite with dimensions usually of 10×10×10 Centimetres (i The University of Arizona (also referred to as UA, U of A, or Arizona) is a Land-grant and space-grant public institution It was the product of the work of about 50 students, ranging from college freshmen to Ph. D. students, over the course of several years. It was launched, after being postponed several times, onboard a Dnepr on July 26, 2006. The Dnepr rocket (Дніпро Dnipro; Днепр Dnepr) is a space Launch vehicle named after the Dnieper River.

Listening
To listen to SACRED if it had made orbit, you would have needed the following:
- The keplerian elements, in order to know where the satellite is pointed. The elements of an orbit are the parameters needed to specify that Orbit uniquely given a model of two point-masses obeying the Newtonian laws of motion and the
- A radio capable of operating on 436. 870 MHz, which will change with doppler shifting. The Doppler effect (or Doppler shift) named after Christian Doppler, is the change in Frequency and Wavelength of a Wave for
- 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).
- The UA Cubesat GS software would help, however, it is not currently available to the public.
- A good antenna system, the design of the antennas is not optimal.
Components
SACRED had the following components included:
- 6 solar cells
- Aluminum frame - built to spin-stabilize through sunlight
- Power board (used to hold batteries, maintain 5V and 3. A solar cell or photovoltaic cell is a device that converts Solar energy into Electricity by the photovoltaic effect. Spin-stabilisation is the method of stabilizing a Satellite by means of spin 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 on July 26, 2006, at 19:43 UTC onboard a Dnepr rocket. Rincon 1 was a Cubesat built by the Student Satellite Program of the University of Arizona. Events 657 - Battle of Siffin. 811 - Battle of Pliska; Byzantine Emperor Nicephorus Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar. The Dnepr rocket (Дніпро Dnipro; Днепр Dnepr) is a space Launch vehicle named after the Dnieper River. The launch failed shortly after takeoff and SACRED was destroyed.
