Stable platforms are not necessarily the same as stable lines of sight nor do stable platforms necessarily provide stable
boresight alignment among instruments. Success in stabilizing lines of sight requires the unified treatment of the
disparate arts of structures and optics. Segregating these arts can lead to insoluble problems in the subsequent hardware.
Unified methods are available but need to be applied early in the conceptualization in order to properly allocate the
resources (mass, size, stiffness, resonances, apertures, optical paths, motors, encoders, gyroscopes etc.) among the
disciplines, all of which compete for a limited supply.
