Evaluation of functional expectations of thematic consumers from optical space remote sensing systems of medium resolution

Abstract

According to the results of direct interaction with various groups of consumers, it was established that the structure of requirements in all thematic areas at the present time comes to the fore geographic coverage, regularity and frequency of shooting. The second priority is to ensure the quality of the spectroradiometric characteristics in the context of their absolute performance and stability in the time series of the entire archive of the survey with the ability to provide data in physical quantities of reflectivity, or spectral brightness of the reflected radiation / brightness temperature. The requirements for spatial resolution within a separately allocated class of data, as well as the presence of a panchromatic channel are not significant for the majority of respondents. In the understanding of thematic users, the mediated requirements for the characteristics of the target remote sensing equipment are formed through direct requirements for the initial remote sensing data. When creating a promising ERS satellite on the part of the state customer, it is advisable to conduct regular advanced studies of user expectations and preferences in order to fully coordinate and integrate them into technical specifications for various products of the space system. In general, for effective generalization of various, often opposite, functional expectations, it is advisable to conduct a comprehensive discussion that provides a feedback mechanism from both authorized representatives of main consumers and developers of target equipment and space remote sensing systems.
