Disturbances
Disturbance Torques
Gravity gradient, aero, solar pressure and residual magnetic — worst-case sizing sum.
Actuators
Wheel Sizing
Momentum storage from cyclic/secular torques, wheel torque, class comparison table.
Actuators
Magnetorquer & Dumping
Torque from dipole × field, dump time, required dipole and detumble estimate.
Pointing & Agility
Slew Agility
Bang-bang slews: torque ↔ time, peak rate and momentum, off-nadir ground offset.
Pointing & Agility
Pointing Budget
RSS error-source table → total 3σ accuracy vs requirement, with ground projection.
Pointing & Agility
Geolocation Error
Ground error from attitude, ephemeris, timing and terrain at any off-nadir angle.
Reference
Sensors & Actuators
Typical sensor accuracies, gyro grades, wheel/magnetorquer classes, field vs altitude.
