Abstract : The Stellar Inertial Design Guide was completed to provide weapon system planners with design and trade off data on the application of stellar inertial guidance techniques to ballistic weapons. Data are presented on hardware, software, and operational aspects of the stellar inertial system, the highlights of which are: (1) A summary of stellar inertial advantages and impact of stellar-aided guidance system on other subsystems, and on weapon system operation; a discussion of the impact of stellar inertial techniques on MIRV accuracy; (2) A detailed accuracy study of various deployment modes at ranges of 1000, 5500, and 7000 NM; based primarily on UNISTAR implementation, data are presented on the effects of time of sight, star position, trajectory shaping, initial condition variations and inertial component errors on the on target error; also included is a presentation of the overall weapon system accuracy; (3) A presentation of software analytics necessary to support a stellar inertial guidance system; included are the methods of star selection, generation of correction terms, validation algorithm, determination of target bias and stellar sensor model updating; (4) Hardware implications of stellar inertial guidance system including a study of various SIMU configurations, ADC requirements and loading, and stellar sensor design criteria.
