Abstract
Infrared 14-16 micron band earth horizon radiance measurements have been made by the Static Earth Sensor on the IRS-1A remote sensing spacecraft launched in March, 1988. The satellite carries a 4-head Static Earth Sensor detecting radiance from the earth horizon in the Carbon Dioxide emission band at 15 microns. Four separate Germanium lenses with thermopile detectors and processing electronics are used. The output is converted into radiance in Wm-2sr-1. This is the radiance measured by the detectors and emitted from the atmosphere at about 30-40 km altitude over the Sensor crossing points. The Sensor outputs are used to derive the roll and pitch errors of the spacecraft.
