“…Furthermore, PINTA can be easily combined with the other components and libraries of the GSOC mission planning tool suite, such as the timeline web viewer TimOnWeb, the planning library PLATO, the event-calculation library SCOTA, or the so-called "Swath Preview and Ordering Tool" (SPOT) [7]. Of course, that is just as important as the well-established integration with the other GSOC sub-systems, such as flight dynamics, satellite and ground station monitoring and control, via generic interfaces.…”

“…Furthermore, there are numerous other corresponding plug-ins with very specific functionalities for the various mission planning systems. The only examples to be mentioned at this point are those for the FireBird mission, without going into too much detail: the "PlanningRequestImporter", the "DatatakeInfoFileGenerator" and the "EnvelopeRequestImporter" [7].…”

“…The main objective of the mission planning system was the generation of consistent and conflict-free timelines in order to command the payload and background sequence operations. Furthermore, the preplanning and ordering process for acquisitions of the Infrared Camera System had been supported [6] [7].…”

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 experience and heritage within the ground segment could be considered in an early stage of the C&DH software design. The efficiency of data storage and retrieval for example will profit from the mission planning tools at GSOC in use for the Firebird mission (see [11]). Therefore, Service 11 and Service 15 of the ECSS Packet Utilisation Standard (PUS) were implemented in the C&DH software.…”

Eu:CROPIS (Euglena and Combined Regenerative Organic-Food Production in Space)is a biological life support mission scheduled for launch in 2017 on-board a Falcon 9 rocket. The spin stabilized satellite will be operated under different levels of acceleration to investigate the growth of tomatoes under simulated Mars and Moon gravity. It comprises two pressurized greenhouses, which are rotated around the spacecraft longitudinal axis, a radiation detector and a secondary payload from NASA AMES research center. Each greenhouse compartment will be operated for 6 months at different rotational speed in order to simulate different gravitational forces. Special care has to be taken in the design and the operations of Eu:CROPIS because biological processes may not be disturbed during spacecraft anomalies, and stable thermal conditions and lighting cycles must be assured.The 250 kg satellite is built by the DLR Institute for Space Systems and will be operated by the German Space Operations Center (GSOC) -another DLR institution. This allows an exceptionally close cooperation between the operations team and the spacecraft manufacturer. Decisions can be made together on whether a technical solution is to be implemented within the space segment or the ground segment. This approach minimizes the overall mission costs and maximizes the scientific output. Operational benefits arise from the on-board data handling, which permits the re-use of existing mission planning systems and minimizes adjustments to the mission control and data system. Additionally, an experimental but more powerful downlink mode may be used operationally after successful checkout, which could reduce the downlink time and related costs. This paper gives an overview of the operations concept including LEOP and routine operations, data dissemination and the interfaces to the user segment. It will also describe the technical innovations that have been made in the ground segment to avoid additional effort on the space segment. A new application was developed and added to the Central Checkout System, and is being used for Assembly, Integration and Test (AIT) as well as for the development of flight control procedures.

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.
