SSE will develop calibration and initialization techniques for candidate lci missile systems. Initial conditions will be characterized with respect to expected environments, reaction times, accuracies, *. And reliability expectations. Life cycle costing will be stressed. Candidate options will be analyzed specifically for tradeoffs in weapon system effectiveness initial costs, maintainance costs, readiness availability, commonality of subsystems for applications requiring different levels of performance, and training costs and complexity. Potential for upgrading will be addressed to accommodate changing requirements over life of the weapon system. Options using the same basis components for interchangeability, economics of production and supply, testing commonalities and training simplicity. The investigators and upgrading missile guidance systems for the defense department. They have been associated with the major manufacters of inertial instruments and will review the current capability of the industry. An intensive effort is planned that will lead to complete design studies in the later phases.
