ART will be enriched by the consider covariance analysis module testing the impact of the introduction of the altimetric observations on the state estimation process without having the real data. Edition Notes Includes bibliographical references and index.

These results come from astrometry, radiometric tracking and spacecraft imaging data and estimating all the major Saturnian satellites.

The altimetric data have been received from CO. T13 and T25 have the lowest numbers of observations so they are precessed but not included in results discussion. Volume 3, Volume 4, The imaging mode is selected while the spacecraft altitude passes from km to its minimum value, then outbound observations are repeated in reverse order.

This research can be divided in four parts. You might also like.

The second part is concerned with the fundamentals of orbit determination. Radar data acquisition is a type of remote sensing technique. Jacobson [8] obtained 1- uncertainties for Titan of 40 km along R, km along T and 50 km along N. Meetingabstract P11D Elaborazione del segnale radar Close. User Area Create Account. It is the problem of determining the best estimate of the orbital parameters of a spacecraft or a celestial body, whose initial state is unknown, from observations influenced by random and systematic errors, using a mathematical model that is not exact.

Although our estimation has been made only for Titan and yields particular and local solutions, the results are fully satisfying.

Since the altimetric observation errors were segnael available, we have used a constant value for the weight of 80 m for all the observations corresponding to the maximum resolution value that the instrument achieves approximatively.

Our research can be further extended to other mission scenarios in order to reach picagdi better accuracy in the orbit determination of natural satellites by the means of altimetric data collected on board spacecrafts by radar or laser instruments. New data sets coming from the last part of the nominal mission and from its extended part will be included in the research and processed by SOSYA?

In fact, radar altimetry involves bouncing microwave pulses off the surface of the target body and measuring the time it takes the echo to return to the spacecraft. For each available flyby, we give its general description, as duration and the closest approach distance and time.
