Detailed Description

catapult launch timing system

  • Phase 1: Zero Roll, Climb Pitch, Zero Throttle
  • Phase 2: After detecting the Start Acceleration
    Zero Roll, Climb Pitch, Full Throttle
  • Phase 3: After getting the GPS heading (time based)
    Place climb in front of us
    GoTo(climb)
