1. An antenna system for an aircraft for use with a global positioning system comprising:
- an aircraft having an aircraft attitude determination system providing attitude data relating to aircraft roll;
a translation module connected to the aircraft attitude determination system receiving the attitude data and outputting output data;
a processor receiving the output data from the translation module and providing a drive signal;
a controller receiving the drive signal from the processor;
an articulator driven by the controller; and
antenna attached to the articulator driven by the controller oppositely to the aircraft roll.

Abstract
An antenna system is disclosed including a GPS antenna which is driven by an articulator in an opposite direction to aircraft roll. Aircraft roll is sensed by an onboard navigation system and translation module sends a signal to a processor which provides a drive signal to the articulator. As the aircraft rolls in one direction, the antenna is driven oppositely to maintain the vertical orientation of the antenna.
