ASTOS 9.3 incorporates multi-body dynamics simulation based on the DCAP software.
ASTOS supports now system concept analysis and comprises complete mission analysis capabilities.
Astos Solutions has delivered to ESA/ESTEC a piece of software that supports mission planning and the identification of suitable landing sites.
The 11th annual Intercollegiate Rocket Engineering Competition (IREC) has been held in June 2016 in Green River, Utah. 52 teams presented their rockets and the Amateur Rocket Edition of the ASTOS software has been used by seven of them!
Astos Solutions has signed a contract with the DLR space agency to perform a phase 0 study about the design of a nano-launcher. The aim of the study is to identify the most cost-effective system that shall place a nano-satellite in a Sun-synchronous orbit
