The '''Advanced S.A.S. Module''' is a toggleable module that acts as a sort of Autopilot to stabilize and help keep a rocket on course.

The '''Advanced Inline Stabilizer''' is a toggleable [[reaction wheel]] that provides torque to a craft. Extra torque means that the player's spaceship will rotate faster when ordered to, resulting in a more nimble feel to the craft. The Inline Advanced Stabilizer is the 'Small' size reaction wheel.
 
 
== Description ==
 
{{Quote|After many years of research, STEADLER Corps rocket scientists discovered that Kerbal crewmembers just can't be trusted to keep a spacecraft under control. The Advanced S.A.S Module adresses that issue by correcting flight controls continuously. It is highly recommended that crewmembers are kept unaware of the presence of such a device, as experience shows that many Kerbals will see that as a 'challenge to their flying prowess'.|STEADLER Engineering Corps}}
 
 
 
== Usage ==
 
Advanced S.A.S. module does not have to be placed anywhere in particular to function, however it will cease to function if jettisoned. Unlike [[S.A.S. Module | S.A.S. modules]] Advanced S.A.S. does not applies any forces itself and only 1 module per ship is effective.
 
It uses controlable airfoils (like [[AV-R8 Winglet]]) and [[RCS]] to control the ship's rotation, so you might want to add these elements if you are planning to use Advanced S.A.S.
 
 
 
 
 
==Theory==
 
The [[S.A.S.]] and Advanced S.A.S. modules use a P.I.D. system, which stands for “Proportional, Integral, Derivative”.
 
* ''Proportional'' means the S.A.S. module applies a turning-force that is proportional to the displacement from the "target" orientation. In other words, the further off-line the ship, the harder the module tries to correct it.
 
*''Derivative'' means the S.A.S. module takes the rate-of-turn of the ship in to account, and tries to apply a force against the turn. So the faster the ship is pitching, yawing, or rolling, the harder the S.A.S. module tries to stop the turn. This is supposed to dampen the action of the S.A.S module, preventing overshoot, as well as dampening any fast turn or roll.
 
* ''Integral'' means the S.A.S. module increases the corrective force the longer the ship is off-target. So if the ship is constantly "not-quite" on target, the S.A.S. module will ramp up the force used to correct the ship's orientation.
 
 
 
Unlike S.A.S., Advanced S.A.S. module uses other components to control the ship:
 
* [[Airfoil | Airfoils]] - useful only in the atmosphere. Effect depends of the ship's airspeed and component placement.
 
* [[RCS]] - they must be activated and have [[FL-R25 RCS Fuel Tank | fuel]]. Effect also depends on component placement.
 
* Gimballing engines (planned in future releases)

The Advanced Inline Stabilizer is a toggleable reaction wheel that provides torque to a craft. Extra torque means that the player's spaceship will rotate faster when ordered to, resulting in a more nimble feel to the craft. The Inline Advanced Stabilizer is the 'Small' size reaction wheel.

Product description

The Advanced Inline Stabilizer module containing a larger, heavier array of reaction wheels. These spin very quickly to create torque without wasting propellant. These larger wheels are driven by proportionally larger electric motors, so keep an eye on your Electricity levels.
