Paper Abstract

The Dual Cone Scanner (DCS) a single-head earth horizon sensor which provides altitude and two-axis attitude information with minimal sun or moon error, will fly on the USAF Phillips Laboratory TAOS mission as part of an autonomous spacecraft navigation demonstration in 1993. These sensors also include an optional sun/moon visible light optical channel and employ a 1750 CPU-based signal processing electronics package. Barnes has since developed an analog processing technique which achieves a significant reduction in weight, power, and cost, making the DCSs available for small satellite applications. Optional features include a light emitting diode built into the detector that can be used for self testing or mission simulations and secondary radiance processing algorithm to reduce errors due to earth radiance variations. The sun/moon detectors used on the TAOS sensors may be incorporated in the new design in the future.
