“…One example was the need to extend the PINTA modelling language to handle one main disadvantage with the "OrderedTimeDependencies". Therefore, a template/instance mechanism was introduced for "Tasks" and "Groups" (see [9] for details). Also, an algorithm was implemented to allow the user to reschedule all activities assigned to a conflicting time dependency by only one click or shortcut.…”

In the recent years, the "Program for INteractive Timeline Analysis" PINTA, developed at the German Space Operation Center (GSOC), was continuously improved and experienced several evolution steps. PINTA is a GUI application running on Windows-based computer systems, whose main purpose is to serve as the anchor tool for a mission planning operation's engineer when generating, modifying or analysing a mission timeline. This is supported by calling automatic planning algorithms of the embedded generic planning library "PLAnningTOol" PLATO, using input of the embedded orbit propagation and event calculation library "SpaceCraft Orbit and GroundTrack Analysis Tool" SCOTA, or its expandability through plugins.PINTA is the generic basis of many semi-automated mission planning systems for past, current and future spacecraft projects operated at GSOC. It is used or has been used for the missions Grace, TET-OOV, FireBird, Grace-FollowOn, Eu:CROPIS and is currently prepared for CubeL. Furthermore, PINTA serves as the timeline analysis tool for validating the TerraSAR-X/TanDEM-X mission planning system.The variety of use cases was further extended to support Launch and Early Orbit Phases (LEOPs) in its special "SoEEditor" configuration as the new generic editing tool for the so-called "Sequence of Events". It was successfully used for the satellites Biros, HAG-1, PAZ, Grace-FollowOn 1 & Grace-FollowOn 2, Eu:Cropis, EDRS-C and is currently in preparation for EnMAP. In addition to LEOP's, the SoEEditor was also capable of supporting the constellation maneuvers for the TerraSAR-X/TanDEM-X mission.Besides all these use cases, the paper at hand will especially describe how PINTA was even further extended to not only tackle spacecraft-based but also ground-based scheduling. On the one hand it serves as an "On-Call Tool" to support the on-call shifts by automatically generating conflict-free role-based shift plans for all subsystems by considering various constraints like person outages, working hours, role-conflicts, etc… The plan can then be further adapted manually to cope with user change-requests. On the other hand it is used as a "Multi-Mission-Control-Room-and-pass-Scheduler" (MuMiCoRoS) to coordinate the ground-station booking of all LEO (low-earth orbit) satellites: TerraSAR-X, TanDEM-X, TET, Biros, Grace-FollowOn 1 & 2 and Eu:CROPIS. In order to avoid ground-station and operator conflicts between the missions, an automatic and combined plan for all satellites is generated which can then be further modified manually if necessary.As another use case, PINTA (a.k.a. GPT; Galileo Planning Tool) supports the Galileo Service Operation (GSOp). The planning process involves three timelines: a Short-Term Plan (STP), covering the next ten days, two Mid-Term Plans (MTP) for the Operational (OPE) and the Validation (VAL) chain), covering the next 15 weeks, and a Long-Term Plan (LTP), covering the next 15 months. The activities in these timeframes cover all subsystems of Galileo: Flight Ops, Control segment, Mission segment, remote sit...

The application of quantum algorithms on some problems in NP promises a significant reduction of time complexity. This work uses Grover's Algorithm, designed to search an unstructured database with quadratic speedup, to find valid a solution for an instance of the on-call operator scheduling problem at the German Space Operation Center. We explore new approaches in encoding the problem and construct the Grover oracle automatically from the given constraints and independent of the problem size. Our solution is not designed for currently available quantum chips but aims to scale with their growth in the next years.

“…Furthermore, it enables the MPS operator to regularly export a "Background Sequence" of recurring basic commands during LEOP. Both configuration items that are used for this purpose, TimOnWeb and the SoE Editor, are generic MPS tools; these are described in detail in [18].…”

“…Second, the space segment is responsible for producing the bus and the hyperspectral imager, its integration and testing, as well as the launch; these activities are led by OHB System AG. Third, the ground segment [10][11][12] links the user and space segment by providing facilities and systems for operating the satellite and retrieval of the targeted scientific data; it is led by the Earth Observation Center (EOC) and the German Space Operations Center (GSOC) at DLR.…”

The Environmental Monitoring and Analysis Program mission (EnMAP) is a German hyperspectral Earth observation mission, currently scheduled for launch in 2020. The EnMAP Mission Planning System (MPS), developed and operated by the German Space Operations Center (GSOC), is one of 15 subsystems constituting the EnMAP Ground Segment. Its main task is to compile and maintain a conflict-free timeline for routine operations that does not violate any constraints of the spacecraft (e. g. regarding power or onboard memory); this timeline will regularly be commanded to the spacecraft. This paper gives an overview of the current EnMAP MPS design, including the special requirements of the EnMAP mission, the components of the MPS and its most important external interfaces. The design of the EnMAP MPS largely builds on our experience gathered during the TerraSAR-X/TanDEM-X mission and has been developed further. Novel technologies include the Reactive Planning framework, which particularly stands out due to its high responsiveness to user input. Particular attention is furthermore paid to the inclusion of cloud coverage and sunglint information into the planning process-two challenges which are specific to EnMAP observing in the optical and near infrared part of the spectrum.
