The Arc-Second Alignment of Sun-Seeking Optical Detectors.

摘要

The CRLS-229 Solar X-ray Spectrometer/Spectroheliograph experiment to be flown on the USAF Space Test Program (STP) P78-1 satellite uses crossed Refractosyn sun detectors to verify the satellite solar pointing. A technique utilizing solar radiation was devised to find the relationship between each detector's null axis and the normal to its flat front surface. The front surface is then used, with an autocollimator, to align the detectors to the experiment view axis. This report describes the alignment procedure and alignment tests performed with the payload installed in the spacecraft. (Author)
