The sensor of the Meteosat-7 is a three-channel imager known as the Visible and Infrared Spin Scan Radiometer (VISSR) (which is also the name of the GMS imager). This imager has one channel for visible radiation, one for detection of water vapor, and one for infrared radiation. Channel properties are given in the following table:

High-resolution PDUS data from Meteosat channel A2 (1694.5) is disseminated in two formats: A and B. The A format is full-disk and the B format covers the European, Northern African, and Middle Eastern regions.

In the A and B formats, the VIS channel data are indicated as coming from the "southern" (VISs) or "northern" (VISn) detector mounted in the radiometer. This means that during the scanning of the Earth, the VISs detector scans the line immediately to the south of the VISn detector.
