PyCon 2.0 (Python Connect) is currently being developed as the successor of the highly successful middleware that has been developed to support the MCS/SATMON Client Virtualization of the Columbus project in 2014. It will be the next-generation Virtual Desktop Infrastructure solution for the Columbus project, which will also support the control and deployment of a variety of Docker Images and Kubernetes Services together with the classical deployment of a variety of virtual machines and WebApps already running in the Col-CC environment.

Analytical work for the definition of requirements, design and interfaces for the evolution of a Columbus Monitoring and Control System Rebuild (MCS-R) has progressed through the Phases B1 and B2. The intermittend Phase B3 shall therefore be used to demonstrate use of the integrated prototypes in a test environment for an end-to-end test embedding already existing Columbus TM/TC interfaces and showcasing general feasibilty of the derived system archichtecture and its maturity.

In the framework of a Columbus programme lasting until 2024, the migration of current MCS functions towards the next generation of MCS (based on EGS-CC) is currently being prepared and analyzed. The essential Phase B2 approach consists of engineering activities (requirements re-engineering, software architectural design engineering), prototyping activities (design and development of prototypes) as well as the preparation of a development & deployment plan for the future system.

PyCon (Python Connect) was developed to support the MCS/SATMON Client Virtualization of the Columbus Project at DLR/GSOC. It provides the middleware that is necessary to manage and configure the connection and assignment of Thin Clients to MCS Clients and SATMON Clients. Therefore, it consists of a PyCon DB that holds all information about physical machines and virtual machines, PyCon Config that provides a graphical user interface to administer the assignment of virtual machines to Thin Clients and PyCon Login that consists of an interface for the Thin Client for end user interaction.
Project Role:
Technologies used: MySQL, Python, PyQt, ZeroMQ, JSON
In order to obtain statistically significant data from the CALIPSO mission and to draw concrete conclusions for the aspired MERLIN mission, a software was developed as the need for a fast and easy way to process the data was apparent and no such tool was publicly available.
Project Role:
Technologies used: Python, PyQt, HDF
