Question 4

Which of the following statements about the accuracy that can be obtained with the LAAS (local area augmentation system) of the satellite navigation system NAVSTAR/GPS is correct?

Accepted Answer

The closer the receiver is to a LAAS ground reference station, the more accurate is the aircraft position fix.

Answer

A LAAS cannot correct for satellite timing and orbital position error.

Answer

The increase in accuracy of position fixes is independent of the aircraft position in relation to the LAAS ground reference station.

Answer

A LAAS corrects the position of the aircraft by relaying the information via a geo-stationary satellite.
