The flight ended up mostly as a checkout and data gathering flight for our upgraded avionics stack and still-in-development rocket software stack.

L-11 Objectives

  1. Launch our LV2.3 airframe summer 2014
  2. Successful flight to at least 75% of projected altitude; recover all hardware intact.
  3. Telemetry
  • get data from:
    • Inertial sensors
    • Events (e.g., 'launch')
    • Commands
  • Record telemetry on rocket
  • Live stream to ground
  • Record on ground
  • Real time display on ground
  • Record on data creating device
  1. Ground Support
  • Remote, safe, digital ignition control
  • Effective recovery
    • Coordination between recovery teams and mission control
    • Know rocket location immediately after landing
    • Easy transportation back to flight line
  1. Experiments
  • Roll control
    • Documented algorithm and analysis
    • Include control data in telemetry
  • Record raw GPS RF environment to SD card
  • Digital Video
    • Downward facing camera
    • Record locally
    • Live digital feed of camera to ground in integrated telemetry stream
    • Record on ground
    • Secondary upward facing camera
