The ORBIT14 software for testing GR and alternative theories of gravity with the BepiColombo mission |
|
Abstract |
The ORBIT14 software system has been developed by the Celestial Mechanics Group of the University of Pisa starting since 2007 as a new dedicated software for MORE, the Mercury Orbiter Radioscience Experiment of the BepiColombo mission. The idea was to have a software tool independent from the existing ones like ODP (Orbit Determination Program) and MONTE (Mission-analysis, Operations, and Navigation Toolkit Environment). ORBIT14 is able to generate simulated tracking observables (range and range-rate), on-board accelerometer measurements, on-board camera angular observations and to solve-for a large list of parameters of interest by a global least-squares fit. An innovative constrained multi-arc strategy is applied in the tracking measurements processing, and state-of-the-art error models are taken into account for each type of measurements involved. In this talk, we will highlight the main features of our software system showing some simulation results about the relativity experiment of the BepiColombo mission. |
