摘要：The PEGASUS (Policy support for European Governments by Acquisition of information from Satellite and UAV borne Sensors) project's aim is to provide an economic way to gather high resolution data (visual, IR and thermal imagery, laser altimetry, SAR, atmospheric measurements) from a high altitude platform. Because the platform will not be manned, it will be able to operate continuously for weeks or months. The paper describes the business model for the data acquisition to information delivery flow. During the system's operation, it will acquire data for storage in a centralised database, where it's conformance to national and international standards is certified. The information derived from the data will be made available to the public via Internet. In case of emergency situations, the system will be able to provide data in near real-time, even in adverse weather. Special attention is paid to evaluate the economic viability of the project and the remote sensing applications for which information can be provided
