Lifeline Astrogation Buffer
developed by Cybot Galactica, the Lifeline was a data storage mechanism that allowed a starship pilot to offload a portion of their astromech droids's computer memory, thereby by backing up any data stored by the droid. It provided starship pilots with a way of reaching their destination, even if their astromech should fail. In the event of an astromech failure, the Lifeline could be connected to a ship's navigational computer in order to input the desired destination.
