Abstract This paper describes new developments of the software package USOC (Unified System for Orbit Computation). This package is used by the European Space Agency for the mission analysis of artificial satellites and interplanetary probes. USOC is a versatile tool for solving initial and boundary value problems for orbits in the solar system. Included also are auxiliary calculations like eclipse time, coverage from a ground station, a planetary lander or a data relay satellite, time into the radiation belt, the magnetosphere or any other domain of space defined around a planet. USOC is not a program, but a program builder. Through a conversation with a preprocessor, the user builds his own program, tailor-made to his application. Following the answers of the user, the preprocessor chooses the corresponding modules out of a library and prepares the input data. The latest USOC development was dedicated to the inclusion of natural moon as central body, allowing to perform trajectory and auxiliary calculations in planetary systems.
