No, it does not. If you believe that it does, please provide a published reference.
Boeing spokesmen declined to elaborate on which sensor inputs are used to provide the data in the tanker design. The options include using data from the angle of attack vanes on both sides of the cockpit, or an angle of attack vane and inertial gyroscope.

The other algorithms include a number of other parameters in the mix, seems that inertial sensors (gyros and accelerometers) alone can't provide needed data.
Concur, I think, with all of this, that additional sensors are needed to augment the algorithms. (just as AB has done with the A350) Far too many issues with shielding, pitch, sideslip, and turns, not to mention vertical winds which the fixed pitot flat lines
