Abstract
An analysis of the atmospheric refraction corrections at the DSS-13 34-m diameter beam waveguide antenna for the period covering July through December 1990 is presented. The current DSN atmospheric refraction model and its sensitivity with respect to sensor accuracy are reviewed. Refraction corrections based on actual atmospheric parameters are compared with the DSS-13 station default corrections for the six-month period. Average blind-pointing improvement during the worst month would have amounted to 5 mdeg at 10 deg elevation using actual surface weather values. This would have resulted in an average gain improvement of 1.1 dB.
