Description
The Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) is a visible and near infrared radiometer for observing land and coastal zones and provides better spatial land coverage maps and land-use classification maps for monitoring regional environment. The AVNIR-2 is a successor to the AVNIR onboard the Advanced Earth Observing Satellite (ADEOS) launched in August 1996.

Its main improvement over AVNIR's is its instantaneous field-of-view (IFOV). The AVNIR-2 provides 10-meter spatial resolution images compared with the 16 m resolution of the AVNIR in the multi spectral region. The higher resolution was realized by improving the CCD detectors (AVNIR: 5,000 pixels per CCD, AVNIR-2: 7,000 pixels per CCD) and their electronics. Another improvement is a cross track pointing function for prompt observation of disaster areas. The pointing angle of AVNIR-2 is + and - 44 degrees.
