RADAR is a multimode instrument that uses the five beam antenna feed assembly associated with the spacecraft high gain antenna to transmit and receive electromagnetic radiation according to different operative modes: 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.

History Created April 1, 4 revisions Download catalog record: The altimetric data have been received from CO. Volume 3, Volume 4, The minimum value of standard deviation of the estimated position is m, while the maximum value is 5. This research can be divided in four parts. Check nearby libraries with: The second part is concerned with the fundamentals of orbit determination. Meetingabstract P11D You can now embed Open Library books on your website!

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. 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 Radarr System. The global mean of residuals at the first iteration is m and it decreases to the global mean at the last iteration of?

T13 and T25 have the lowest numbers of observations so they are precessed but not included in results discussion. User Area Create Account. The total number of altimetric measurements processed is and they are not uniformly distributed in the 14 flybys: In fact we proved that the standard deviation errors effectively decrease by the use of different a priori variance matrices.

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. Jacobson [8] obtained 1- uncertainties for Titan of 40 km along R, km along T and 50 km along N.

Our research can be further extended to other pivardi 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 standard deviation of the velocity ranges from a minimum of 6. The altimetric measurements simulation module will be improved by the introduction of the possibility of adding noise to the signal.

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.
