Before GPS and even more advanced technology, star-gazing was a reliable way to determine geographic location. The SR-71 was equipped with a sensor that locked on to stars in space and relayed that information back down to Earth in order to give an updated location. It was so accurate, mind you this is in the 1960s, that it guaranteed a correct positional read within 300 feet while the plane was traveling 2,200 mph. This sensor sits in a similar place as R2D2 sat on Luke Skywalker’s aircraft, thus the connection.
