“…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.

“…Due to the fact that near-earth objects can be illuminated by the Sun during nighttime, optical observation is a feasible and realistic technique for space debris detection. To date, several countries and organizations have carried out optical space debris surveys and published their results (Schildknecht et al 2001(Schildknecht et al , 2004(Schildknecht et al , 2008Rykhlova et al 2001;Seitzer et al 2004;Molotov et al 2008;Porfilio et al 2004;Alby et al 2004;Musci et al 2004Musci et al , 2005Hebert et al 2001;Sun & Zhao 2012).…”

Specific challenges arise in the task of real-time automatic data reduction of optical space debris observations. Here we present an automatic technique that optimally detects and measures the sources from images of optical space debris observations. We show that highly reliable and accurate results can be obtained on most images produced by our specific sensors, and due to optimizations, the whole pipeline works fast and efficiently. Tests demonstrate that the technique performs better than SExtractor from the point of view of fast and accurate detection, therefore it is well suited for data reduction of optical space debris observations.
