A DIGITAL SOLAR ASPECT SENSOR

Abstract

The solar aspect sensor performs the analog-todigital conversion of data optically. To accomplish this, it uses a binary Gray code light mask to produce a digital indication, in vehiclefixed coordinates, of the elevation and azimuthANGLES OF INCIDENT LIGHT FROM THE SUN. This digital solar aspect sensor system, in Explorer X, provided measurements of both elevation and azimuth angles + or - 2 degrees at a distance of over 140,000 statute miles. (Author)
