These present detail methodology procedures for characterization; technical operational information about specific being evaluated; provide summary test measurements, data retention practices, analysis results, conclusions.CBERS–4A joint Chinese-Brazilian medium-resolution launched December 2019 China National Space Agency/National Institute Research (Brazil) on Chang Zheng 4B rocket from Taiyuan Satellite Launch resources monitoring. The CBERS–4A mission continues CBERS that has been continual operation since launch CBERS–1 1999.The was designed built Academia Chinesa de Tecnologia Espacial/National uses Phoenix-Eye bus. carries camera wide field imager sensors land imaging swath panchromatic sensor high-resolution imaging. assessment focused only. More available “2020 Joint Agency Commercial Imagery Evaluation—Remote Sensing Compendium” at http://www.cbers.inpe.br/lancamentos/cbers04a.php.The team completed analyses to characterize geometric (interior exterior), radiometric, spatial performances. Results these indicate provides an interior (band-to-band) performance range −0.02 −0.16 pixel; exterior accuracy −22.02 (−1.47 pixels) −16.06 meters (−1.07 pixels); radiometric –0.006 0.925 (offset slope); relative edge response 0.39 0.44, full width half maximum 2.38 2.56 pixels, modulation transfer function Nyquist frequency 0.001 0.013.

Identification of Parasite-Host Habitats in Anxiang County, Hunan Province, China Based on Multi-Temporal China-Brazil Earth Resources Satellite (CBERS) Images
Remote sensing is a promising technique for monitoring the distribution and dynamics of various vector-borne diseases. In this study, we used the multi-temporal CBERS images, obtained free of charge, to predict the habitats of the snail Oncomelania hupensis, the sole intermediate host of schistosomiasis japonica, a snail-borne parasitic disease of considerable public health in China. Areas of s...

متن کاملOptimized Filtering and Compression System for an Earth Observation Satellite
Most earth observation satellites in their daily image processing routine operate using the “store and forward” mechanism; this mode of operation is not efficient due to the huge amount of data that has to be stored on-board the satellite (but cannot due to memory constraints). The Cape Peninsula University of Technology (CPUT) 3U CubeSat named ZACUBE-02 will perform the filtering and compressi...
