GRAVMOD-2 is a software tool developed by Astos Solutions and GMV for ESA.

It adds guidance analysis and on-board manoeuver capabilities to the gravitational modelling core of GRAVMOD-1 originally developed by DEIMOS. The unique mathematical models and architecture make it particularly suitable for the modelling of the gravity field of highly irregular bodies such as small moons, asteroids or comets. GRAVMOD-2 is composed of two main modules:

The goal of this project was to evaluate the state-of-the-art of European and US solid propulsion stages and to create an Excel-based design model/workbook for solid propulsion stages. The tool is intended to be used, amongst others, by the ESA CDF for either selecting existing solid rocket motors from a suitably populated database or creating preliminary designs for new solid rocket motors. Having a workbook to model stages based on solid propulsion will help assessment studies to perform trade-offs taking solid propulsion stages into account.

The OBCP-BB study has performed the following tasks: Assessment of current OBCP implementations for Space systems, considering both Application procedures (OBAPs) and Operation procedures (OBOPs), and providing some statistics figure about the OBCPs used in different ESA missions and projects Assessment of the ECSS-E-ST-70-01C standard particularly in the context of the specification of the OBCP software building block in the FSW Reference Architecture. The analysis has covered both the OBCP concept and the system capabilities defined by the ECSS standard.

Public awareness of the urgent need for mitigating the environmental impacts of human activities is ever growing. This results in a more and more stringent public environmental legislation and an increasing public pressure. In this context, the European Space Agency (ESA), as a public sector intergovernmental organisation, wants to put the environmental concern as a priority in all its activities, as expressed in its Framework Policy on Sustainable Development.
