The move towards higher frequency bands like 26GHz or 32GHz for scientific satellite data downlinks calls for the need to better characterise the atmosphere at the sites where ground antennas are located. For this reason ESA is undertaking the deployment of microwave radiometers at its Deep Space station locations. This paper reports the results of the first two years of site characterisation at the...
The main focus of this study is the characterization of internal noise of the Microwave Radiometer (MWR) to be located at an ESA Deep Space Antenna (DSA) site, to accurately retrieve the tropospheric path delay along the line-of-sight of the deep space probe. This would enable precise tropospheric calibration of radiometric observables (range and range-rate) with particular reference to the BepiColombo...
