Uncertainty analysis of initial orbit determination in the minimum radar admissible region [PDF]
Scientific ReportsThe poor accuracy of the single solution of the initial orbit determination (IOD) affects the precise orbit determination, target matching and arc-segment correlation. This paper proposes a method for analyzing the uncertainty of the IOD results based on

Effect of Observation Geometry on Short-Arc Angles-Only Initial Orbit Determination [PDF]
Applied Sciences, 2022 Space-based optical sensors are attracting increasing research attention as they can measure the angle of space targets over large areas, facilitating low-cost, wide-area space target surveillance. Studying the effect of observation geometry on short-arc

Initial Orbit Determination for Distant Objects [PDF]
The Astronomical Journal, 2004 Initial orbit determination for distant objects can be made a simple linear problem with explicit solutions. This is similar to stellar parallax work, with very difficult observations but simple computations. A very simple procedure for computing ephemerides for distant objects is proposed.

Journal of Astronomy and Space Sciences, 2019 The Optical Wide-field patroL-Network (OWL-Net) is a Korean optical space surveillance system used to track and monitor objects in space. In this study, the characteristics of four Initial Orbit Determination (IOD) methods were analyzed using artificial ...

Initial orbit determination of BDS-3 satellites based on new code signals
Geodesy and Geodynamics, 2018 For the two newly launched satellites (PRN number 27 and 28) of the future global BeiDou navigation satellite system (BDS-3), there is no available broadcast ephemeris data and other initial orbit information, but the initial orbit is the fundamental of ...

Probabilistic Initial Orbit Determination [PDF]
, 2016 Future space surveillance requires dealing with uncertainties directly in the initial orbit determination phase. We propose an approach based on Taylor differential algebra to both solve the initial orbit determination (IOD) problem and to map uncertainties from the observables space into the orbital elements space. This is achieved by approximating in

A Multimodal Differential Evolution Algorithm in Initial Orbit Determination for a Space-Based Too Short Arc [PDF]
Remote Sensing, 2022 Under the too short arc scenario, the evolutionary-based algorithm has more potential than traditional methods in initial orbit determination. However, the underlying multimodal phenomenon in initial orbit determination is ignored by current works.

Initial orbit determination with the multibeam radar sensor BIRALES
Acta Astronautica, 2020 Abstract In this work we present a conceptual analysis of the use of the novel Italian multibeam radar sensor BIRALES for space surveillance. The dedicated orbit determination algorithm is described in detail. The algorithm is tailored to the peculiar configuration of the receiver gain pattern and is devoted to both reconstructing the track of the ...
