RapidEye Earth-imaging System (REIS)
The REIS sensors on the RapidEye constellation mean that for the first time, there is a constellation of five Earth imaging satellites that contain identical sensors, which are in the same orbital plane and are calibrated equally to one another. An image from one RapidEye satellite will be identical in characteristics to an image from any of the other four satellites, thus allowing access to an unprecedented amount of imagery collected on a frequent basis. RapidEye's sensors produce imagery in five spectral bands (Red, Green, Blue, Red Edge and Near Infrared). Over 70% of RapidEye's imagery has a view angle of less than 10°, as the view angle of RapidEye imagery is always less than 20°.
The instrument is also referred to as JSS-56 (Jena-Optronik Spaceborne Scanner-56) as well as MSI (Multispectral Imager) in the mission literature.
