“…Optical observations of satellites and space debris, especially in high Earth orbit (HEO), have been successfully performed for many years in several countries and a very rich literature reports the results (see, for instance, Africano et al, 2004;Jarvis et al, 2001;Schildknecht et al, 2001Schildknecht et al, , 2004aIsobe and Tajama, 1997;Porfilio et al, 2003a).…”

“…Optical observation is now widely used in space debris observation because it is unrestricted by the distance to observation objects and is cost-efficient compared to radar, and several countries and organizations have carried out optical space debris observation [4][5][6][7][8][9][10][11][12][13][14][15][16]. Electro-optical (EO) sensors are the primary instrument for optical observation systems.…”

A single electro-optical (EO) sensor used in space debris observation provides angle-only information. However, space debris position can be derived using simultaneous optical measurements obtained from two EO sensors located at two separate observation sites, and this is commonly known as triangulation. In this paper, we propose a new triangulation algorithm to determine space debris position, and its analytical expression of Root-Mean-Square (RMS) position error is presented. The simulation of two-site observation is conducted to compare the RMS positioning error of the proposed triangulation algorithm with traditional triangulation algorithms. The results show that the maximum RMS position error of the proposed triangulation algorithm is not more than 200 m, the proposed triangulation algorithm has higher positioning accuracy than traditional triangulation algorithms, and the RMS position error obtained in the simulation is nearly consistent with the analytical expression of RMS position error. In addition, initial orbit determination (IOD) is carried out by using the triangulation positioning data, and the results show that the IOD accuracy of two-site observation is significantly higher than that of the single-site observation.

“…The combinatorial explosion in the number of intervals to be scheduled has been caused by the increasing number of space debris to be observed with optical ground station. Therefore, new scheduling approach is needed to provide a solution to the new requests [1][2][3][4][5][6][7][8][9][10]. Based on the dynamic of the scenario and the requirements of the mission, the ground station operators generate a set of requests characterized by constraints associated with these time windows [11].…”

The scheduling model of orbital debris can be considered as composed by a set of optical ground station which move with the surface of the Earth, a set of space situation awareness centre which can be assumed connected to ground station, and orbital debris travelling through different kind of orbit generating visibility windows when the line of sight (LOS) to ground station exists. To solve this, scheduling problem can be considered as the allocation of observing time of the telescope to collect measurements of the debris (i.e., to improve orbit or attitude determination, spin rate evolution, etc.). The increasing number of space debris to be observed with optical ground station has caused the combinatorial explosion in the number of intervals to be scheduled. Therefore, new scheduling approach to provide a solution to the new requests is needed. In the framework of the Agreement between Italian Space Agency (ASI) and National Institute of Astrophysics (INAF) "Supporto alle attività IADC e validazione pre-operativa per SST " (N.2015-028-R.0), S5Lab research group has developed a network of observatory fully dedicated for space debris observations. Moreover, a scheduler called NICO (Networked Instrument Coordinator for debris Observations) has been developed specifically designed for the harmonization of individual user requests by considering meteorological and astronomical constraints. This paper outlines the advantages of the developed custom solution based on modular architecture. NICO's architecture is based on a multilayer system: the front end is designed to allow external registered users to specify their observing requests and to assign specific scientific priority; the back-end is changed for the business logic by determining the visibility windows for each request and to solve the conflict. The implemented conflict solver solution is based on genetic algorithms. This paper outlines the results of the application of NICO scheduler to the 2018-IADC (Inter-Agency Space Debris Coordination Committee) international optical observing campaigns.
