T2-02 Reaction Wheel Desaturation

1. Momentum Saturation & Desaturation

Reaction wheels absorb external disturbance torques by accelerating internal flywheels. Once a wheel approaches its 6,000 RPM mechanical ceiling, it saturates and can no longer provide control authority in that direction. Dumping stored angular momentum requires applying an external counter-torque with RCS thrusters while commanding the wheel to brake.

2. Coupled Momentum Dump Strategy

Your spacecraft begins with its X-axis reaction wheel saturated near 5,800 RPM:

• Brake the Saturated Wheel: Apply reverse motor torque on rw_x to decelerate the flywheel toward zero RPM.
• Counteract Induced Body Torque: Braking a spinning flywheel transfers its angular momentum into the hull. Fire opposing cold-gas RCS couples to keep body rates bounded.
• Stabilize Attitude & Wheels: Bring all reaction wheels below 500 RPM while holding pitch, yaw, and roll rates below 0.10 deg/s for 3.0 seconds.

3. Prompt Your Autonomous Agent

Prompt Antigravity to implement a closed-loop momentum dump routine:

Update our flight agent to solve mission T2-02 (Reaction Wheel Desaturation):
1. Monitor [ADCS_RW] wheel speeds and [IMU_ROT] angular rates.
2. Decelerate saturated reaction wheels below 500 RPM while firing RCS thrusters to cancel the momentum transfer into the spacecraft body.
3. Stabilize all body angular rates below 0.10 deg/s for 3.0 seconds.
