Compact High Resolution Imaging Spectrometer (CHRIS)

Abstract

This paper describes a hyper-spectral imaging system known as CHRIS (Compact High Resolution Imaging Spectrometer) which has been designed for operation on a spaceborne platform. CHRIS is designed to take images of the Earth in multiple spectral bands over the spectral region 415 to 1050nm. Band selection is programmable. The instrument is planned to be launched in 2001 on an agile small satellite of the 100kg class. This satellite will operate in a sun-synchronous, high inclination orbit with an altitude in then range 700 to 830km. The instrument can provide 19 spectral bands with a spatial sampling interval of 25m at nadir and 37 bands at 50m, at an altitude of 830km. The field of view of CHRIS is 19 km from 830km altitude.
