Abstract
The calibration of the Halogen Occultation Experiment (HALOE) sun sensor is described. This system consists of two energy-balancing silicon detectors to provide coarse azimuth and elevation control signals and a silicon photodiode array to provide top and bottom solar edge data for fine elevation control. All three detectors were calibrated on a mountaintop, using the Langley plot technique. The conventional Langley plot technique was modified to allow calibration of the two coarse detectors, which operate wideband. A description of the test setup is given. The HALOE instrument is a gas correlation radiometer that is now being developed for the Upper Atmospheric Research Satellite.
