The European Commission funded NEO-MAPP project in support of the ESA Hera mission: Near-Earth Object Modelling And Payload for Protection

<p>NEO-MAPP stands for Near Earth Object Modelling And Payload for Protection. This project is funded by the H2020 program of the European Commission and addresses the topic "Advanced research in Near Earth Objects (NEOs) and new payload technologies for planetary defence" (SU-SPACE-23-SEC-2019).</p> <p>NEO-MAPP selected as primarily reference scenario the ESA Hera mission, which has recently been approved by the ESA Council at Ministerial Level, Space19+, in November 2019 for launch in 2024. The main goal of NEO-MAPP is to support the development and data analysis of NEO missions, as Hera and provide significant advances in both our understanding of the response of NEOs to external forces (in particular a kinetic impact or a close planetary approach), and in the associated measurements by a spacecraft (including those necessary for the physical and dynamical characterization in general).</p> <p>The NEO-MAPP objectives, include: (1) Pushing the limits of numerical modelling of the response of NEOs to a kinetic impact, as well as of their physical and dynamical properties while maturing European modelling capabilities linked to planetary defence and NEO exploration; (2) Increasing the maturity of multiple spaceborn and landed European instruments directly related to planetary defence, while focusing on measurements of surface, shallow sub-surface and interior properties of NEOs; (3) Developing algorithms and simulators to prepare for closeproximity operations and payload data analyses and exploitation; (4) Developing innovative and synergetic measurement and data-analysis strategies that combine multiple payloads, to ensure optimal data exploitation for NEO missions; (5) Developing and validating robust GNC strategies and technologies enabling surface interaction and direct response measurements performed by CubeSat or small/micro-lander architectures.</p> <p>Building on the expertise of NEO-MAPP participants, who are directly involved in the Hera mission and some of them also in other relevant missions (e.g., NASA OSIRIS-REx, JAXA Hayabusa2 and MMX), the NEO-MAPP consortium is ideally set to further advance NEO scientific research and payload technologies. NEO-MAPP will also dedicate considerable resources to developing important and innovative synergies between the two sub-topics. As such, NEO-MAPP will provide significant advances in our understanding of NEOs while at the same time build upon and sustainably increase expertise of European scientists and engineers in both planetary defence efforts and small-body exploration.</p> <p>Acknowledgement: This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 870377 (project NEO-MAPP).</p>

A New Object Tracking Framework for Interest Point Based Feature Extraction Algorithms

This paper presents a novel object tracking framework for interest point based feature extracting algorithms. The proposed framework uses the feature extracting algorithm without making any changes and it relies on outlier detection, object modelling, and object tracking. At first, the keypoints are extracted by using a feature extraction algorithm. Then, incorrect keypoint matches are detected by the DBScan algorithm. The second step of our tracking framework is object modelling. The object model is defined as a bounding box. The box model has six points and each of these points has its own Gaussian model. Finally, the Gaussian model is performed for object tracking. In object tracking, the old five values are retained to detect incorrect position information. Thus, while the object movements are softened, the instant deviations are eliminated also. Our interest point based object tracking framework (IPBOT) works with any interest point based feature extracting algorithm. Thus, a new algorithm can be added to the object tracking framework with a short integration process. The experiment results show that the proposed tracker significantly improves the success rate of the object tracking.

THE SPECIFICATION OF HYDROLOGICAL MODEL REQUIREMENTS FOR BOG RESTORATION

INTRODUCTION Within the scope of biodiversity and sustainable ecosystem development, the restoration of a bog’s ecosystem is important because by reducing the drainage effect on the bog, the negative impact on adjacent intact or relatively intact raised bog and other wetland hydrological regimes is lowered. Degraded bogs are mires with a disturbed natural hydrological regime, or those partly exploited for peat extraction. However, the hydrological regime can be restored and peat formation is expected within 30 years. The restoration of a bog’s hydrological regime can be accelerated by filling up the drainage ditches. In the course of researching scientific literature, the author has found no evidence of a system dynamics model developed to simulate tree cutting intensity in degraded bogs after filling the drainage ditches for the purpose of speeding up the restoration of the hydrological regime. Thus, this approach is an innovative way of solving the problem. Bog hydrological systems are complex systems with many components, thus an interdisciplinary approach must be applied which combines hydrology, biology, geography and meteorology with computer sciences. Specification requirement technique is a useful tool for determining the elements that shape a bog’s hydrological system and interact with each other, thus providing the design for a simulation model. MATERIAL AND METHODS In the opinion of the author, the most suitable specification requirement tool to determine components forming the bog hydrological system is (OOAD), because it is applicable both in system dynamics and object modelling systems. Based on OOAD, it will be able to build system dynamics models in STELLA system dynamics and the GEOframe NewAGE modelling system, which is based on an object modelling system framework. OOAD principles are fundamentally based on real world objects (Powell-Morse, 2017) - in this case, the elements forming a bog’s hydrological system. OOAD combines all behaviours, characteristics and states into one analysis process, rather than splitting them up into separate stages, as many other methodologies would do (Powell-Morse, 2017). OOAD can be divided in two parts – Object-Oriented Analysis (OOA), and Object-Oriented Design (OOD). The products of OOA serve as models from which we may start an object-oriented design; the products of OOD can then be used as blueprints for completely implementing a system using object-oriented programming methods (Booch, 1998). In the study of the boundaries of the bog hydrological model, theoretical methods such as case study and content analysis were mainly used - specifically evaluative, explorative and instrumental review methods. RESULTS This study helped to understand complex interrelationships that exist between different elements within a bog’s hydrological system. The bog hydrological system boundaries were clarified, and the simulation model specification requirements were determined. DISCUSSION The next step is to develop simulation models in STELLA system dynamics and the GEOframe NewAGE modelling system and compare the performance. These simulation models will be made to represent water movement in a bog’s hydrological system from water input by means of precipitation to water output through interception, sublimation, evaporation, transpiration, lake outflow and overland flow. The input data will be loaded manually from the QGIS Open Source Geographic Information System and Excel databases. It will be possible to generate output data in the form of frequency tables, graphical analysis, review tables, GIS raster files and others. CONCLUSION The determination of tree thinning intensity in degraded bogs using modelling is a new innovative approach which should allow the water level of ecosystems to be restored faster and more efficiently, thus increasing natural diversity, improving the quality of life of local people and promoting bog recreational ability.
