  7. Predicted drift

  8. Vehicle Test Plan

  9. Subscale Flights • 2 launches that both exhibited coning • Have one final test scheduled for March 8th • 2 Potential solutions • Decrease length • Increase fin size

  10. Emergency Subscale Project Plan

  11. Payload Design Overview – Sensor Array • GPS • Accelerometer • Magnetometer • Vibration • Temperature • Pressure • Voltage • Current • SD Data Storage

  12. Payload Design Overview - Payload Fairing

  13. Payload Design Overview – Hazard detection • Pseudocode: • Read image from Raspberry Pi Camera • Search the image for adjacent pixels that have RGB values outside of a defined range • Determine if these adjacent pixels occupy a big enough area • If so, mark the exterior by changing the pixels in a rectangle encasing the pixels to red • Send this image to the transmitter • Loop

  14. Payload Integration
