An advanced imaging system, the Optical angle of 45 degrees. Its peak power consumption is less than Imaging System (OIS) is being developed for a small Earth 21.0 W during imaging operation and its total mass is less than observation satellite, RASAT. OIS will produce high-7.0 kg. resolution images in panchromatic and multi-spectral While BILSAT produces panchromatic images of 12.6 m bands and it consists of one optical and one electronics GSD using a frame-type imaging system, RASAT will produce units. Recently, we have completed the development of the images of higher resolution and fidelity for scientific research OIS engineering/qualification model (EQM). As part of and many civil / environmental applications. verification of EQM, functional and environmentral tests were performed. Key system features of OIS and test result TABLE I for EQM are summarized. KEY FEATURES OF OIS Parameter Feature
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
