Evolution of the 'Trick' Dynamic Software Executive and Model Libraries for Reusable Flight Software

In response to a need for cost-effective small satellite missions, Odyssey Space Research is proposing the development of a common flight software executive and a fundamental set of reconfigurable flight software modules. This application will directly affect the development cost by avoiding the need to develop software from scratch and allowing the efficient reuse of flight software even across vehicles. Odyssey proposes to use NASA's Trick simulation environment to form the basis of the flight software executive and to use NASA's Common Model Library to form the basis for the reconfigurable modules. Trick is currently capable of producing a software architecture that is easily modified to allow the use of software modules in the production of a simulation framework. We are proposing modifying and adapting Trick for the production of software that easily moves out of the simulation realm and into the embedded flight software realm. Our proposed approach to providing reusable flight software is innovative in that it takes a well established open platform simulation tool and advances it to a level where it can be combined with reconfigurable software modules. This in turn can be used to produce highly reconfigurable flight software allowing for the same software development environment to be used across the entire life cycle of the system.
