A method and system for controlling a movable appendage on an aerospace vehicle independent from the position of the aerospace vehicle. First and second beacons containing actual position information for the movable appendage are tracked and acquired by first and second beacon tracking sites. The beacon tracking sites report the azimuth and elevation data relating to the position of the movable appendage to a processor where a correction command is determined based on an error calculated from the position data and a desired position. The correction command is communicated to the movable appendage so that appropriate correction to the desired position can be made.

The conveyor system as recited in claim 2, wherein said second section extends from said first section at an obtuse angle. 4. The conveyor system as recited in claim 2, wherein each second section of each upstream diverting track terminates adjacent said at least one downstream diverting track. 5. The conveyor system as recited in claim 2, wherein said second section of each upstream diverting track of said plurality of upstream diverting tracks is operably connected to the second section of an adjacent upstream diverting track. 6. The conveyor system as recited in claim 2, wherein said at least one downstream track is a pair of downstream tracks, and wherein said second section of each upstream diverting track is operably connected to a downstream diverting track of said pair of downstream diverting tracks. 7. The conveyor system as recited in claim 2, wherein said conveying surface has a first side and an opposing second side, said at least one downstream diverting track laterally extending from said first to said second side, where said second section of each upstream track terminates adjacent said at least one downstream track, proximate to said second side. 8. A conveyor system for diverting articles comprising: a conveying surface moving in a particular direction, said conveying surface defining a pair of opposing sides; at least one branch conveyor extending from said conveying surface such that articles traveling on said conveying surface can be diverted onto said at least one branch conveyor; a plurality of diverters movable between a diverting state and a non-diverting state; a plurality of movable pushers mounted on said conveying surface, each movable pusher configured to move from one side to the other side of said pair of opposing sides when a diverter of said plurality of diverters is in said diverting state; a control system configured to determine the length of articles conveyed on said conveying surface; and a diverting system operably connected to said control system, said diverting system having at least one downstream diverting track extending substantially across said conveying surface, and a plurality of upstream diverting tracks, each upstream diverting track extending partially across said conveying surface, wherein said diverting system simultaneously diverts at least one movable pusher along said at least one downstream diverting track when the leading end of the article to be diverted is positioned over said at least one downstream diverting track, and at least one movable pusher along at least one upstream diverting track of said plurality of upstream diverting tracks proximate to the trailing end of the article. 9. The conveyor system as recited in claim 8, wherein each upstream diverting track is operably connected to an adjacent upstream diverting track. 10. The conveyor system as recited in claim 8, wherein each upstream diverting track terminates adjacent said at least one downstream diverting track. 11. The conveyor system as recited in claim 8, wherein said pair of opposing sides include a first side remote from said at least one branch conveyor and a second side proximate to said at least one branch conveyor, wherein each upstream diverting track terminates adjacent said at least one downstream diverting track, and proximate to said second side. 12. The conveyor system as recited in claim 8, wherein each upstream diverting track of said plurality of upstream diverting tracks has a first section substantially parallel to said at least one downstream diverting track, and a second section configured to rotate the article being diverted. 13. The conveyor system as recited in claim 12, wherein said second section of each upstream diverting track extends from said first section at an obtuse angle, and towards said at least one downstream diverting track. 14. The conveyor system as recited in claim 12, wherein said second se
