This report describes the development details for breadboard, engineering, and flifght models of the SPIBS instrument. A fourth model, a rocket model SPIBS, was built for use in a rocket charging experiment. This report provides a description of all phases of the SPIBS instrument development process and the key technical difficulties and successes. Corroborative results obtained by AFGL personnel using the delivered instruments are referred to as appropriate to support the most significant conclusions. 收起
