CONICAL SCAN IMPACT STUDY Volume II:Small Local User Data Processing Facility

摘要

Studies were performed to determine the impact of a conical scan versus a linear scan multispectral scanner (MSS) instrument on a small local-user data processing facility. User data requirements were examined to determine the unique system requirements for a Low Cost Ground System (LCGS) compatible with the Earth Observatory Satellite (EOS) system. Candidate concepts were defined for the LCGS and preliminary designs were developed for selected concepts. The impact of a conical scan MSS versus a linear scan MSS was evaluated for the selected concepts. It was concluded that there are valid user requirements for the LCGS and, as a result of these requirements, the impact of the conical scanner is minimal, although some new hardware development for the LCGS is necessary to handle conical scan data.
