Currently the software only features a module for mission analysis which was inherited from the previous Space Trajectory Analysis Tool by ESA which has already been updated to compile despite an untouched code base since 2011 on current machines. The source code already compiles on Gentoo Linux and Ubuntu Linux. It is planned to revise the code to also support other Linux distributions, Windows and Mac OS X. Starting from successful builds on various platforms, the code base will be upgraded to replace the currently used Qt4 with the latest Qt5 library. Further modifications will include the seperation of the code base into two parts, one handling the computations involved in the software, and the other providing a graphical user interface. Based on this framework more modules will be developed to cover more aspects of the design of spacecrafts and space missions. Efforts in the project are currently focused on the evaluation of appropriate software libraries for the different tasks. After completion an environment will be designed to combine the different libraries in a proposed co-simulation environment to allow coupled simulations of different solvers.
