Relocation of Advanced Water Vapor Radiometer 1 to Deep Space Station 55

In June of 2004, the Advanced Water Vapor Radiometer (AWVR) unit no. 1 was relocated to the Deep Space Station (DSS) 55 site in Madrid, Spain, from DSS 25 in Goldstone, California. This article summarizes the relocation activity and the subsequent operation and data acquisition. This activity also relocated the associated Microwave Temperature Profiler (MTP) and Surface Meteorology (SurfMET) package that collectively comprise the Cassini Media Calibration System (MCS).

Ka-Band Tiny Transmitter for the New Millenium Program

The size, mass and cost of telecommunications systems on deep space missions have increased at almost an exponential rate over the last thirty years. Great cost and size reduction of these systems can be achieved by reducing the cost and size of the transponder component of the radio subsystem. An advanced technology X-and Ka-band (8 and 32 GHz) Tiny Transmitter is being developed at JPL for the New Millenium program and is described in this paper.
