Recently, the potential of lidar for addressing applications of interest to aerospace systems has been recognized. Ground-based lidars are ideally suited for the calibration of instruments onboard satellites. Other aerospace applications include monitoring the impact of launch vehicles upon the environment. Future systems are envisioned carrying lidars for atmospheric characterization. In this paper we will discuss briefly the lidar technique, outline important aerospace applications for which lidar is ideally suited, and describe the mobile lidar system under construction at The Aerospace Corporation.","PeriodicalId":262646,"journal":{"name":"1996 IEEE Aerospace Applications Conference.

The lab will facilitate the transition of technologies to flight. The infrastructure will be such that virtually any type of spacecraft payload or subsystem can be brought in, as long as the technologies are mature. The emphasis is placed upon the hardware in the loop (HIL) simulation evaluation. End to end HIL simulation has several benefits within the Phillips Lab, including (1) bringing forth spacecraft integration problems before spending millions of dollars to put a system into space, (2) exploring scenarios for in-flight anomalies and hardware and software failures, (3) showing the utility of component technologies and subsystems to the warfighter, (4) evaluating various potential mission concepts, (5) selling programs to upper management, (6) training of operators and educating lab personnel in how theater operations are performed with respect to obtaining data from space, Based on monetary constraints, the lab must leverage off of existing hardware in the loop facilities, such as Wright Lab's Kinetic Kill Vehicle HIL facility (KHILS), JPL's Flight System Testbed (FST), Arnolds Engineering Development Center (AEDC), etc., in terms of networking in, mimicking equipment, and utilizing lessons learned. The cost for setting up the HIL facility will be further reduced by building the lab based on requirements for the individual projects coming in, rather than up front construction of a HIL laboratory.","PeriodicalId":262646,"journal":{"name":"1996 IEEE Aerospace Applications Conference.

The architecture concept defined the system component's life cycle framework. The architecture process is based on TRW's system and software engineering process assets. The process description includes a discussion of the engineering activities and the four principal system engineering processes used to direct the work effort: (1) architecture framework, which established the scope of the architecture; (2) requirements management, which established the boundaries for the architecture; (3) modeling and simulation, which established performance requirements and drove the architecture preliminary design; and (4) analyses, which provided overall substantiation for the engineering architecture effort. The process guided the rapid development of the C3I system architecture concept; the work was part of a concurrent engineering effort.","PeriodicalId":262646,"journal":{"name":"1996 IEEE Aerospace Applications Conference.

The 3-D structure offers an order of magnitude improvement in global communication bandwidth over traditional backplane techniques. This is accomplished by simultaneously reducing interconnect length (propagation delay) and dramatically increasing physical connectivity between layers of electronics. A characterization cube is described that will demonstrate the key technologies behind the 3-D packaging concept. These include synthetic diamond substrates for heat conduction, spray cooling for heat removal, double-sided multi-layer MCM interconnect, and high density connectors that support the required inter-layer signal bandwidth. Size and weight benefits of 3-D packaging are quantified in a specific application comparison. Results suggest that machines normally confined to a computer room environment can be repackaged with this technology for airborne, shipborne, or mobile applications.","PeriodicalId":262646,"journal":{"name":"1996 IEEE Aerospace Applications Conference.

The chord transform can be used to detect geometric edge structural content within an image.

The design of system fault protection for the Cassini spacecraft will be described at a high level in order to define the guiding principles of the design. This will include examining driving requirements, high level design trades, and major architectural elements, including practical details of their design. Finally, a detailed design description will be given of two Cassini fault protection responses which are likely to be used on most other spacecraft.","PeriodicalId":262646,"journal":{"name":"1996 IEEE Aerospace Applications Conference.
