The estimation of the path delay due to water vapor is a crucial aspect for the calibration of the Doppler observables of a deep space probe. The advanced water vapor radiometer (AWVR) developed by the Jet Propulsion Laboratory (JPL, NASA) already proved its capability to accurately estimate the path delay during the entire Cassini mission. Here, from the AWVR measurements, a scalar sky status indicator (SSI) was developed as a criterion for selecting the radiometric path delay estimations in the orbit determination process. Results indicate that the use of such index allows a reduction of the range rate residual root mean square (rms). This article has been accepted for inclusion in a future issue of this journal.

“…NASA [4,5] and ESA [6] use two widely separated antennas to track a transmitting spacecraft by measuring the phase difference and the related time difference (phase delay) between signals arriving at the two stations (e.g., Goldstone and Cerebros, about 8 000 km apart, Cerebros and New Norcia), a technique known as Differential One-way Range (delta-DOR) [2,6]. Theoretically, the delay depends only on the positions of the two antennas and the spacecraft, but, in practice, the delay is affected by several sources of error, one of which is the Earth's troposphere.…”

“…Detailed studies pointed out that atmospheric delay fluctuation is the dominant error component on time scales greater than about 100 s [5]. Now, in clear sky conditions almost all the power in the atmospheric fluctuations at frequencies less than 0.01 Hz is due to water vapor.…”

By applying the Synthetic Storm Technique to the large collection of rain rate time series measured at Spino d'Adda, in 8 years of continuous observation (1993-2000), we have simulated 1120 time series of simultaneous attenuation and phase delay due to rain in a 20° slant path at 8.4 and 32 GHz. The relationship between phase delay and attenuation exceeded with the same probability is given by a power law, whose exponent is 0.73, likely to be independent of frequency. The results are useful for satellite and deep space tracking. This work is partially supported by ESA-ESTEC Contract AO/1-5425/07/NL/HE, 2007: Assessment of propagation effects in the W frequency band for space exploration.
