Abstract

Images sent by spacecrafts allow the observation of satellites and rings with a large resolution and from a large number of geometries, however the analysis of these data is not a trivial process. In general, the most common analysis process can be divided in the following steps: 1. search of the images; 2. calibration; 3. Localization; and 4. analysis. The image navigation process, i.e., the spatial identification of the region being observed, is made through geometric computations with the use of the program SPICE (Spacecraft, Planet, Instrument, C-matrix, Events). SPICE provides computational routines that allow to extract telemetry data of the spacecraft and the instruments appointment stored in binary files called kernels. Then, knowing the problem geometry it is possible to determine the observer position (spacecraft), the illumination condition (position of the Sun) and the state vectors of the target of interest (satellite, ring, planet). After those procedures, the images are ready for the scientific analysis, and the kind of information to be extracted depends on the proposed goals. In the current project, the main goal is to develop a series of computational programs that, from the spacecraft telemetry and the images sent by Cassini, to determine with precision the positions of the spacecraft, the satellites and the rings of Saturn. With those routines it will be possible, for example: * to implement the method proposed by Evans (2000) to determine the orbital osculating and geometric elements of the satellites for a given epoch of interest; * to verify if the most recent data from Cassini confirm the orbital lags of the satellites Prometheus and Pandora; * to continue the mapping of the F ring, initiated by Figueira & Sfair (2013), identifying and measuring the extension of the radial and azimuthal structures of the ring.
