Mission profile: Deployment → Separation → Bonus Hover → Landing

1Primary Mission

  • Deploy from rocket at 700m altitude
  • Autonomous separation at 400m
  • Active descent with autogyro system
  • Real-time telemetry at 1 Hz

2Bonus Mission

  • Hover at ~200m for 10 seconds
  • Maintain altitude via PID control
  • Resume descent after timeout
  • Visual tracking via smoke capsule
