Abstract
A new uplink frequency band (22.55–23.15 GHz) is being planned for use in lunar communications. Since this frequency band lies next to the peak of the water vapor absorption line, atmospheric attenuation statistics were derived from sky brightness temperatures at the lower frequency channels of water vapor radiometers (WVRs) used in the DSN. This article details the approach used to generate these statistics for the three DSN tracking complexes, and presents the statistics for availabilities of 90% and 95%, planned for use in lunar link budgets. Best-month and worst-month statistics are also provided, which can serve as favorable or conservative entries for atmospheric attenuation in telecom link budget tables, respectively.
