Welcome to the AV-Firehorn-Rpi wiki!
- Initial state, the rocket is at rest.
- Rocket on the pad, low sensor data storing rate.
| From | Condition | Command |
|---|---|---|
| ERROR ON GROUND | - | RECOVER |
| CALIBRATION | - | RECOVER |
- Calibration mode to calibrate the sensors (accelerometer, gyroscope, barometer, Kalman filter) and warm-up the GPS.
- Performs checks on electronics.
| From | Condition | Command |
|---|---|---|
| INIT | - | CALIBRATE |
- Safe error state that rises upon electronics or mechanical problems.
| From | Condition | Command |
|---|---|---|
| CALIBRATION | Sensor not detected, Radio signal lost | - |
- This state is meant to manually check that every actuator (servos, solenoids) operates correctly by sending open/close commands to the PR board
| From | Condition | Command |
|---|---|---|
| CALIBRATION | All the sensors are calibrated and ready for use | - |
- The rocket is ready for filling and pressurization.
| From | Condition | Command |
|---|---|---|
| THRUST SEQUENCE | Pression too low in the igniter or combustion chamber | - |
- Initiating thrust sequence. From here, can send an IGNITE command to the propulsion board. Start sensor sampling and data storing at a high rate.
| From | Condition | Command |
|---|---|---|
| ARMED | Pressure above certain level in the igniter and combustion chambers | IGNITION |
- Keep a high sensor sampling and data storing rate.
| From | Condition | Command |
|---|---|---|
| THRUST SEQUENCE | The engine properly ignited and a liftoff has been detected | - |
- The rocket reached the apogee. Vent to depressurize the tanks.
- The recovery commands can be sent to the recovery board in this state only.
| From | Condition | Command |
|---|---|---|
| ASCENT | Apogee detected | - |
| From | Condition | Command |
|---|---|---|
| DESCENT | The vehicle is immobile and fully depressurized | - |
- Manually triggered to try to prevent damage to the vehicle.
- Immediately gives the command to the propulsion board to shutdown the engine and depressurize the tanks (ABORT).
- MANUAL DEPLOY internally calls ABORT before deploying the parachutes.
| From | Condition | Command |
|---|---|---|
| THRUST SEQUENCE | - | ABORT |
| ASCENT | - | ABORT |
| DESCENT | - | MANUAL DEPLOY |

| RECOVER | Move back to INIT to reinitialize the system |
| GET READY | Move to READY STEADY, waiting for the ARM command |
| ARM | Move to ARMED and wait for pressurization |
| IGNITION | Move to THRUST SEQUENCE and ignite the engine |
| ABORT | Move to ERROR ON FLIGHT and lock transitions |
| MANUAL DEPLOY | Move to ERROR ON FLIGHT and deploy the recovery system |
| IGNITER LOX | Open/close the igniter LOX valve |
| IGNITER FUEL | Open/close the igniter Ethanol valve |
