MoQSpace
From planning to data evaluation - this is the motto of the project Modelling software for quantum sensors in space (MoQSpace). The aim is to establish the complete simulation chain of a satellite mission as a workflow. The focus is particularly on missions in which quantum sensors are to be used.
In principle, all phases of space projects can be accompanied by suitable models and modelling frameworks. Simulations offer the opportunity to analyse the feasibility of a mission during the planning phase. For example, depending on the mission objective, the orbit can be planned such that certain areas of the Earth’s surface are passed regularly. This is relevant for geodesy missions, e.g. in order to be able to observe changes in Earth's mass distribution. Accordingly, simulations are also used here to check and verify the requirements of a mission. Furthermore, the anticipated satellite data can be simulated in advance to test evaluation algorithms and optimize the mission.
During the mission, individual sensors may fail or data may be transmitted incorrectly. In these cases, simulations can assist in testing adjustments to manoeuvres or data evaluation algorithms so that the mission can continue successfully despite difficulties.
In addition, individual sections can be simulated after the end of the mission, e.g. to analyse inconsistencies in the recorded data. Lastly, by analyzing data of previous missions, simulation models can be verified and improved.
During the various phases of the mission design, different software tools are used that are suitable for their respective tasks. These tools were previously developed as part of the BECCAL and VirtualEnv projects. The MoQSpace project now aims to continue the development and establish a standardised workflow. At the end of the project a toolchain should be available that emulates all stages of a satellite mission and can be used to design future space missions. Requirement management, simulations and data analysis should go hand in hand. Finally, the developed concept will be demonstrated using a fictitious satellite mission that includes an atomic clock as a payload.
