SPACE-BASED INFORMATION MEASUREMENT SYSTEM FOR LOCATING OPTICAL RADIATION SOURCES. (SOME ASPECTS OF SPACE METROLOGY)

摘要

It is proposed to consider artificial-satellite global observation systems providing remote probing of the Earth from space as space-based information measurement systems performing indirect measurements of some particualr property of the observed object, utilizing mathematical modeling and information-processing algorithms. The models and algorithms are integral parts of space-based information measurement systems and to a considerable extent determine the accuracy and confidence in the results obtained. After it ahs processed the data, the system records an estimate of t he parameters of the observed object and the covariance matrix of the estimation errors. The present article analyzes the meteorological aspects of the operation of space-based information measurement systems as applied to the particular but practically important problem of locating sources of electromagnetic radiation.
