  1. Team Napoleon Launch Readiness Review Connor Strait, Chris Gray, Chad Alvarez, Akeem Huggins, Ashley Zimmer, Tucker Emmett, Ginny Christiansen , Caleb Lipscomb Tuesday, November 26, 2012

  2. Mission Overview • Our Mission is to prove that 3D imaging is possible for small objects close to the camera in space, and that 3D imaging is not viable for large, distant objects in space.

  3. Design Overview • Our satellite consists of a structure made of foam core, with four plastic viewing ports on the front and top of the structure, and a heater. • Our satellite contains two Arduinos • The 1st Arduino has our External Temperature sensor, internal temperature sensor, humidity sensor, pressure sensor, and accelerometer • The 2nd Arduino has a gyroscope and controls our camera rig motor • Our satellite also contains two identical Canon Cameras used for 3D imaging and a GoPro for HD film

  9. GoPro Camera

  10. 3D image testing • We took images with the Canon cameras of known objects close to the cameras over an hour long period. We then attempted to create 3D images from these images • Cameras were successfully synced, and took pictures at the same time • We successfully created 3D images • We were also able to make a 3D video

  13. Functional Testing • We ran all of our sensors in 3 different controlled environments in order to calibrate our environmental sensors. • We subtracted the average value our sensors read during the test from the actual environmental value of the room. • Our final test was in a room of 18 degrees C, a humidity of 35%, and a pressure of 14.673 psi • The accelerometer was placed on a flat surface with the z-axis pointing up

  14. Accelerometer • Results: • Our accelerometer is still a small percentage off actual readings • X-axis reads about .2 g high • Y-axis reads about .16g high • Z-axis reads about .06 g high • The results of this final test will be used to calibrate the accelerometer sensors one more time, and they will be tested again before the flight.

  18. Pressure sensor • Our pressure sensor is fairly accurate, reading about .2 psi low during the test. • We will use this data to make a final calibration to our sensor. • The change in the values of the pressure sensor in a room of constant pressure showed that our sensor is accurate to about +-.04 psi.

  20. Temp Sensors • Our internal temperature sensor was very accurate during the test, reading between 17.5 C and 18.5 for the duration of the test • Our external temperature sensor read about 1.7 degrees C high for the test, and will be calibrated to solve this error.

  21. Internal Temperature Sensor

  22. External Temperature Sensor

  23. Humidity Sensor • Our humidity sensor performed well during the test, reading at about 35% for the duration of the test

  24. Humidity

  25. Gyroscope • To test our Gyroscope, we rotated the gyro about each axis individually 180 degrees in one second. We also recorded the reading of our gyroscope on a flat surface while not moving • We used the results of this test to calibrate our gyroscope • We are not yet able to write our gyroscope’s data to an SD card.

  26. Cold Test • We placed our satellite in a cooler filled with dry ice for an hour and a half and ran all of our sensors. • Our satellite remained above -10 degrees C the entire test, reaching a max temperature of 35 degrees C

  27. Cold Test

  28. Structure Test • Drop Test: • Thrown off bridge between DLC and ITLL • Stair Test: • Thrown a flight of stairs at down Stairs at DLC • Results: • Sides of Structure held up well. • One corner did break open, not enough hot glue was used. • Problem solved by applying hot glue to outside of corners as well as inside

  29. Whip Test • Box whipped around Tucker’s head at a high velocity for 3 minutes • Results: • Main Structure survived • Flight tube became loose during test • Problem solved by applying more hot glue secure the flight tube and by correct placement of paper clips in tube

  30. Whip Test

  31. Predicted Flight Results • We expect to successfully take 3D images of close up objects (other satellites, the balloon) but not of distant objects (the earth, mountains on the earth, the sun, ect.) • We expect all of our sensors to successfully collect and record data to the SD cards. • We expect our satellite’s internal temperature to remain about -10 degrees C for the entire flight.

  32. Worries/Concerns • Cameras remaining in sync for the entire flight • Camera rig not rotating correctly
