RELATIVISTIC ASTROMETRY WITH GAIA: ADVANCIES IN THE RAMOD PROJECT |
Abstract _ |
Aim of the RAMOD project is to solve the general relativistic ray-tracing problem in the gravitational field of the Solar System to the accuracy of a micro-arcsecond in the measurements of angles. The project consists in the construction of a family of models with increasing complexity and accuracy each one acting as test bed for the more advanced ones. The models are operated by numerical codes in a multimodular structure which allows one to activate specific functions according to the need. Here we discuss the latest contribution to the model structure consisting in a new modulus conceived to analyze the error budjet and solve the condition equations. |
