“…Currently the main rule engine of the EGOSMPS was derived from the MEX MPS core functionality [2] based on the EKLOPS [1] rule engine. The reuse of this core library has proven to be a valuable asset to the agency as it provides the implementation of the LMP which many missions already know or have made use of.…”

“…), can be obtained from Eq. (2). Because the discretized orbit in the ECEF frame and the attitude in the LVLH frame from the satelli information are given, the corresponding profiles of the antenna gimbal angles continuously discretized over time.…”

“…If a satellite is equipped with a directional antenna system, a gimbal system is typically mounted between the body and antenna to maintain focus on a GS. Typically, a set of commands to point the directional antenna system toward the target GS, typically called the tracking profile (TP), is uploaded by ground operators [1,2]. Similar to other LEO satellites, the KOrea Multi-Purpose SATellite 3 (KOMPSAT-3) also uses the TP to transmit telemetry and image data to Earth.…”

In satellite operations, stable maneuvering of a satellite's onboard antenna to prevent undesirable vibrations to the satellite body is required for high-quality high-resolution images. For this reason, the onboard antenna's angular rate is typically minimized while still satisfying the system requirement that limits the speed of the onboard antenna. In this study, a simple yet effective method, called the ground station searching method, is proposed to reduce the angular rate of a satellite's onboard antenna. The performance of the proposed method is tested using real flight data from the KOMPSAT-3 satellite. Approximately 83% of arbitrarily selected real flight scenarios from 66 test cases show reductions in the onboard antenna's azimuth angular rates. Additionally, reliable solutions were consistently obtained within a reasonably acceptable computation time while generating an onboard antenna tracking profile. The obtained results indicate that the proposed method can be used in real satellite operations and can reduce the operational loads on a ground operator. Although the current work only considers the KOMPSAT-3 satellite as a test case, the proposed method can be easily modified and applied to other satellites that have similar operational characteristics.

“…At the end of 2010, the decision was taken to move to a new system based on EKLOPS (Enhanced Kernel Library for Operational Planning and Scheduling), which represented the planning standard already used by several ESA missions: Envisat, Mars Express, and Venus Express 8 . After one year of development and validation, the new Mission Planning System was declared operational in November 2011.…”

Cluster is a four-spacecraft mission launched in 2000 to study the Earth's magnetic field and its interaction with the solar wind. Originally supposed to last two and a half years, the mission is now extended until the end of 2014 provided a successful midterm review in June 2012. In time, the Cluster ground segment has undergone a thorough modernization process. Lately, the mission planning system has been the object of the biggest changes. The initial strategy was to optimize the utilization of a single ground station by all four of the spacecraft. This was soon modified to account for a second ground station, in order to increase the science data return. Each station had to be allocated to a specific pair of spacecraft. Such a rigid planning approach became, year after year, more inadequate as the evolving orbit changed the visibility, and the spacecraft power subsystem degraded. Many more ground stations are needed today, and the increased complexity of the spacecraft operations requires the capability for short term re-scheduling. Currently, an interactive and fast adapting mission planning system is used. A key-role is played by Cluster Web, a software package entirely developed by the Cluster flight control team to offer a visual overview of the mission plan and an elegant interface to implement conflict-free changes. Its description is the objective of this paper, together with the discussion of the transition from an 18-years old VMS architecture to a Linux system that took advantage from the on-going development of several mission planning facilities within the European Space Operations Centre. The goal is to underline how a flexible approach and the ability to design and develop ad-hoc tools could cope with continuously evolving operational demands and budget constraints.
