Tropospheric Delay Calibration System Performance During the First Two BepiColombo Solar Conjunctions

Cappuccio, Paolo; Iess, Luciano; Tortora, Paolo +8 more

Media propagation delay and delay-rate induced by the water vapor within the Earth's troposphere represent one of the main error sources for radiometric measurements in deep space. In preparation for the BepiColombo and JUICE missions, the European Space Agency has installed and operates the prototype of a tropospheric delay calibration system (TD…
