Cassini radar : system concept and simulation results
Orosei, R.; Picardi, G.; Seu, R. +1 more
The Cassini mission is an international venture, involving NASA, the European Space Agency (ESA) and the Italian Space Agency (ASI), for the investigation of the Saturn system and, in particular, Titan. The Cassini radar will be able to see through Titan's thick, optically opaque atmosphere, allowing us to better understand the composition and the…
Atmospheric studies with spectro-imaging : prospects for the vims experiment on Cassini
Bellucci, Giancarlo; Bellini, Barbara; Formisano, Vittoria
Spectroscopic observations of Jupiter and Saturn are here reported to show the possible applications to the future data acquired by the instrument VIMS ( Visible and Infrared Mapping Spectrometer) on board of the Cassini Mission. The following images and spectra have been acquired by a similar instrument called VNIR ( Visible and Near Infrared Spe…
Doppler receiver for Cassini radio science experiments
Comoretto, G.
The Ka band tracking capability of the Cassini spacecraft allows for greater accuracy in most Radio Science experiments, but can be used only with the Goldstone DSN complex, i.e. for one third of the total time. A digital receiver has been designed to allow receiving the Ka band signal from a generic VLBI antenna. The receiver interfaces with the …
Cassini Huygens mission : the exploration of the Saturn system. Radio science experiments : Radio Frequency Instrument Subsystem
Perrot, Bruno; Giordani, Roberto
Many of the Cassini radio science experiments will require very stable microwave signals from the ground station that are transponded phase coherently on board the spacecraft. The Radio Frequency Instrument Subsystem is designed to provide this latter capability with high performance downlink signals at S-band and Ka-band. The signal level and pha…
