Mission Description

We are going to build a satellite that will be ableto take panoramic pictures. A balloon will takeour satellite up to approximately one hundredthousand feet, and we will take pictures duringthe entire flight. The satellite will have four

cameras placed inside the shell to capture 360images. All this weighing no more than 1.4 kg.

Mission Goals and NASA Benefits

Our goal is to take pictures at different altitudes bysetting the cameras off with an interval timing circuit

every five and a half minutes once its in the air.This will assist NASA in real time mission planning infinding a secure place to land spacecrafts on otherplanets. This will also help gather more information

about the atmosphere at different altitudes.

System Requirements

Satellite stays attached to the tether during theentire mission.

To prevent equipment (cameras, interval timer,batteries) from freezing we have to insulate thewhole system.

Stabilization of the satellite in order to have clearimages.

Subsystem Description

We have six subsystems which form ourpayload. These are the shell, the cameras, an

interval timer, a power source, insulation, and astabilizer.

Shell Requirements

Our payload will be built out of a foam coresheet to have a light and durable design.

Aluminum tape for extra strength.

The shell has no inputs or outputs, but all theother systems depend on it.

Cameras

Panoramic images will be recorded at differentaltitudes at 360

We will use the Elph Lt advantix camera with apanoramic lens to capture the image needed.

Camera Specifications

Shooting distance : 0.6m to infinite.

Shutter : Combination aperture and programelectromagnetic drive shutter.

Time and date will be recorded on each picture.

Camera Requirements

3V power to operate each camera.

Timer to tell the camera when to take pictures.

Insulation to prevent freezing of the componentsand condensation of the lens.

Stabilizer to have clear images.

Interval Timing Circuit

The entire purpose is to activate the shutter ofthe four cameras at the same time to ensure

360 images at the same elevations.

Velleman Interval Timer

SpecificationsOutput relay with dry switch-over contact :3A/24V

Pulse time adjustable : between 0.5 and 5s

Pause time adjustable : between 2.5 and 60s

Dimensions : 40 x 85mm (1.6" x 3.4")

Timer Requirements

Power supply : 12VDC / 100ma

We will get the required voltage and amps by aseries circuit that consists of a 9V and a 3 Vbattery.

Must be programmed to set the cameras off

every five and a half minutes.

Power Source

Provide separate power sources for cameras,motor, and timer so they can perform their

individual functions.

8/7/2019 CDR-PanSat

19/30

Power Source Requirements

Keep batteries warm to prevent them fromfreezing.

Test the batteries to know the freezing andexplosion points to minimize the probability offailure.

8/7/2019 CDR-PanSat

20/30

Insulation

This prevents our other subsystem from freezingand it will provide cushion for landing.

This will also provide the support for thecameras.

Styrofoam will be the insulator that we will use.

Stabilization

The stabilization helps to reduce the movementof the load so it can take higher quality pictures.

For this project we will use a gyroscope.

8/7/2019 CDR-PanSat

22/30

Requirements of the Stabilizer

The gyroscope will require a High Speed 12VDCHobby Motor. We will get the required voltage

and amps by a series circuit that consists of a 9Vand a 3 V battery.

This motor will spin the gyroscope at

approximately 15,000 RPM.
