A Distributed Aperture Vision System for ground vehicles is described. An overview of the hardware including sensor
pod, processor, video compression, and displays is provided. This includes a discussion of the choice between an
integrated sensor pod and individually mounted sensors, open architecture design, and latency issues as well as flat panel
versus head mounted displays. This technology is applied to various ground vehicle scenarios, including closed-hatch
operations (operator in the vehicle), remote operator tele-operation, and supervised autonomy for multi-vehicle
unmanned convoys. In addition, remote vision for automatic perimeter surveillance using autonomous vehicles and
automatic detection algorithms is demonstrated.

Our aerospace customers are demanding that we drastically reduce the cost of operating and supporting our products. Our space customer in particular is looking for the next generation of reusable launch vehicle systems to support more aircraft like operation. To achieve this goal requires more than an evolution in materials, processes and systems, what is required is a paradigm shift in the design of the launch vehicles and the processing systems that support the launch vehicles. This paper describes the Automated Informed Maintenance System (AIM) we are developing for NASA's Space Launch Initiative (SLI) Second Generation Reusable Launch Vehicle (RLV). Our system includes an Integrated Health Management (IHM) system for the launch vehicles and ground support systems, which features model based diagnostics and prognostics. Health Management data is used by our AIM decision support and process aids to automatically plan maintenance, generate work orders and schedule maintenance activities along with the resources required to execute these processes. Our system will automate the ground processing for a spaceport handling multiple RLVs executing multiple missions. To accomplish this task we are applying the latest web based distributed computing technologies and application development techniques.
