Instrument details
Acronym HRC
Full name High Resolution Camera
Purpose HRC provides grey scale images, approximately 25 km square. It is primarily intended for technology, educational and general public information purposes.
Short description HRC is a miniaturised black and white imager with 5 m ground resolution. It has a detector based on a CCD. It contains 1024 x 1024 pixels of 14 mm size.
Scanning Technique The HRC requires a highly stable and accurate pointing of its two-dimensional CCD to an Earth-fixed target using the "point and stare" feature of the spacecraft.
Resolution A spatial resolution of 8 m.
