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

There’s no description for this book yet. Moreover we give tables that summarize the distribution over time of the altimetric observation sequence. Angeli in Milano, Italy. July 31, History. Since the altimetric observation errors were not pcardi, we have used a constant value for the elaborazoone of 80 m for all the observations corresponding to the maximum resolution value that the instrument achieves approximatively.

History Created April 1, 4 revisions Download catalog record: These results come from astrometry, radiometric tracking and spacecraft imaging data and estimating all the major Saturnian satellites. User Area Create Account. Basic concepts of the radar theory and signal modulation are presented. 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. Il risultato dipende dalla formattazione della citazione.

The first part gives a brief introduction of the Cassini mission and a detailed description of the RADAR instrument on board the satellite with its features and scientific purposes.

In fact we proved that the standard deviation errors effectively decrease by the use of different a priori variance matrices. In order to give a description of the flybys used in the Orbit Determination process, we implemented a simple SPICE-based routine that reads the ephemeris files and gives three output files containing respectively: This research can be divided in four parts. Go to the content. Our research can be further extended to other mission scenarios in order to reach a better accuracy in the orbit determination of natural satellites by the means of altimetric data collected on board spacecrafts by radar or laser instruments.

The second part is concerned with the fundamentals of orbit determination. Statistical orbit determination is the set of techniques that allows the estimation of the orbital parameters of a spacecraft or a celestial body during its motion in the Solar System. In addition, the resulting accuracy of the estimation is due to the short orbital arcs considered in the orbit determination process over which the measurements are taken. The accuracy of our solution is limited by the altimetric measurement errors and by the a priori covariance matrix values applied to the initial conditions of the natural bodies integrated.

These techniques acquire information detecting and measuring changes that the object causes on the surrounding field potential, electromagnetic or acoustic field.

Moreover, the Measurements Simulation part of SOSYA has been enriched the introduction of the module that creates synthetic altimetric measurements at given observation times set. Number of segnlae The minimum value of standard deviation picari the estimated position is m, while the maximum value is 5. Elaborazione del segnale radar Giovanni Picardi.

The imaging mode is selected while the spacecraft altitude passes from km to its minimum value, then outbound observations are repeated in reverse order. T13 and T25 have the lowest numbers of observations so they are precessed but not included in results discussion. Astronautic and Ssgnale Science.

Then by the use of Matlab, the states have been plotted in order to visualize the entire encounters in two different ways: Check nearby libraries with:
