Performance characterization of ESA's tropospheric delay calibration system for advanced radio science experiments
Radio Science(2021)
摘要
Media propagation noises are amongst the main error sources of radiometric observables for deep space missions, with fluctuations of the tropospheric excess path length representing a relevant contributor to the Doppler noise budget. Microwave radiometers currently represent the most accurate instruments for the estimation of the tropospheric delay and delay rate along a slant direction. A prototy...
