It contains 1024 x 1024 pixels of 14 mm size. The field of view (along the diagonal of the detector) is 0.504°. Images are digitised to 10 bits before transmission to the spacecraft.
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.
The Proba-1 HRC (High Resolution Camera) provides grey scale images, approximately 25-km square with a pixel resolution of 5m. The HRC was launched aboard ESA's Proba-1 satellite on 22 October 2001, and is primarily intended for technology, educational and general public information purposes.
HRC was built by the Belgium company OIP Sensor Systems.
