Abstract: A method and apparatus for collecting and distributing information to and from a computing element that is quickly scalable at the installation to varying types and numbers of signals. Standard sized modules containing a generalized set of; computation, discrete I/O, analog I/O, serial I/O, adaptable I/O, etc. or any combination thereof, provide the building blocks that can be attached to each other to provide the desired combination of functions. These modular components are mated to each other through a simple serial interface providing the inter-module communication interface and local power requirements. The modules are quickly stacked together and snapped in place in a manner supporting severe environmental conditions.

Abstract: A navigation and guidance computer system using navigation sensors to determine aircraft position, and automatically control the aircraft to fly from an initial position to intercept and follow a crew-selected rendezvous orbit in accordance with Air Traffic Control and military specified rules. It creates maneuvers that result in smooth, efficient motion of the aircraft from an initial position to the execution of a rendezvous orbit. It controls the aircraft by applying commands to the aircraft's autopilot. The system creates the smooth and coordinated maneuvers by considering and anticipating all constraints on the aircraft flight path by creating a single maneuver that is a re-entry maneuver, an over fly maneuver, and a turning maneuver all as a single turn that is contained entirely within the allowable airspace. All maneuvers are created and executed recognizing the turning capability of the aircraft considering allowable bank angles, current wind conditions and true airspeed.
