The European Space Software Repository (ESSR) is an ESA informational web portal created to promote reuse of Software - including Open Source Software (OSS) - and to provide all parties involved in the European Space software development (in particular SMEs) with access to results of previous investments.
Please click here to register and get full access to the ESSR.
Only a limited number of projects is visible to the non-registered users.
Registration is available for everyone residing in an ESA member state.
