“…It is important to highlight that among different MPOV observation schemes for cataloging the LEO space debris, the dual POV method is the preferable choice due to its superior cost-effectiveness ratio [46][47][48]. Furthermore, dual POV proves highly effective in addressing the challenging issue of in-orbit initial orbit determination of uncatalogued debris.…”

The primary objective of this study is to investigate the efficacy of Support Vector Machine (SVM) regression method to enhance the accuracy of Low Earth Orbit (LEO) space debris orbit prediction using the historical data. Principal Component Analysis (PCA) is employed to efficiently reduce the dimensionality of dataset's feature space and hence optimize the model's performance. This investigation is motivated by the limitations of conventional orbit prediction methods, which often rely on dynamic models with unknown coefficients of perturbation forces and other relevant characteristics of space debris, leading to errors during the prediction process. On the other hand, while the Collision Avoidance Maneuver (CAM) strategy remains crucial for mitigating the threat posed by such debris, precise knowledge of debris coordinates is essential for effective CAM implementation. However, traditional ground-based optical equipment encounters challenges in observing fastmoving debris within the dynamic LEO environment, including atmospheric interference and limited Field of View (FOV). To address these limitations, the secondary objective of this study involves exploring the potential of an in-orbit optical space surveillance network as a promising solution. The system utilizes optical sensors distributed across multiple spacecraft within the Above the Horizon (ATH) constellation, specifically designed to continuously monitor the most densely populated altitude band in LEO. Simulations under different conditions demonstrate that the proposed scheme successfully complements groundbased equipment and dynamic models for debris tracking, thereby improving orbit prediction accuracy. The results of simulations under different conditions demonstrate that proposed scheme successfully complements ground-based equipment and dynamic models for debris tracking, and improving orbit prediction accuracy.

Promising approaches to updating multi-faceted information about space vehicles and objects of space debris involve the addition of networks of ground-based surveillance tools using satellite systems for observing near-Earth space, built on several orbital groups (segments). The purpose of the research is to develop the task of building a satellite system that provides total coverage of a given area of heights above the Earth's surface by the application zones of orbital-based devices that carry out "horizontal observations" (the axis of symmetry of the instantaneous zone of possible application of the "horizontal" observation device lies in the plane of the instantaneous local horizon space vehicle-device carrier). Results: 1) two "symmetrical" methods of solving the problem of choosing the parameters of the grouping of one of the segments of the satellite observation system, which has a well-known, often used structure based on the "rings" of spacecraft in symmetrically spaced orbital planes, have been developed (the grouping should ensure total coverage of the spherical layer in the altitude area of near-Earth space in its environment with the given parameters of the instantaneous cone-shaped zone of application of the observation device; the "width" of the covered spherical layer is chosen as a part of the layer that would be covered using observation devices with the given characteristics with an infinite number of spacecraft based on them); 2) the proposed approach to the construction of a satellite system of "horizontal" observations on several orbital groups of different heights, quasi-optimal according to the criterion of minimizing the number of spacecraft; 3) calculated examples of the application of the developed methods are given, and several approximate estimates are made regarding the implementation of systems based on "horizontal" observations. Conclusions: satellite systems for observing orbital objects based on "vertical" (in the radial direction) observations can be supplemented with the implementation of "horizontal" observations.

“…Therefore, we have to employ multiple space-based sensors to track HGVs. There are mega-constellations in low-Earth orbits (LEOs), which are perfect platforms for those space-based sensors [7][8][9]. For instance, more than 3 000 satellites have been launched to establish the Starlink constellation.…”

In order to effectively defend against the threats of the hypersonic gliding vehicles (HGVs), HGVs should be tracked as early as possible, which is beyond the capability of the ground-based radars. Being benefited by the developing megaconstellations in low-Earth orbit, this paper proposes a relay tracking mode to track HGVs to overcome the above problem. The whole tracking mission is composed of several tracking intervals with the same duration. Within each tracking interval, several appropriate satellites are dispatched to track the HGV. Satellites that are planned to take part in the tracking mission are selected by a new derived observability criterion. The tracking performances of the proposed tracking mode and the other two traditional tracking modes, including the stare and track-rate modes, are compared by simulation. The results show that the relay tracking mode can track the whole trajectory of a HGV, while the stare mode can only provide a very short tracking arc. Moreover, the relay tracking mode achieve higher tracking accuracy with fewer attitude controls than the track-rate mode.
