[edit] About Cassini ISS (Imaging Science SubSystem)

[edit] Instrument Overview

The Imaging Science Substyem (ISS) is used for multispectral imaging of Saturn, Titan, rings, and the icy satellites to observe their properties.

See: The Cassini Mission

[edit] Technical Details

The ISS consists of two framing cameras. The narrow angle camera (ISS-NAC) is a reflecting telescope with a field of view of 0.35 degrees. The wide angle camera (ISS-WAC) is a refractor with a field of view of 0.35 degrees. Each camera is outfitted with a large number of spectral filters: 23 different filters for the NAC and 17 for the WAC spanning wavelengths of light from ultraviolet to the near-infrared. Each camera is a charged coupled device (CCD) detector consisting of a 1024 square array of pixels. The data system allows many options for data collection, including choices for on-chip summing and data compression.
