Positioning Error Estimation Method for Short-Arc Angles-Only Initial Orbit Determination

Journal of Guidance Control and Dynamics
The development of space surveillance capabilities has received increased emphasis with time. Suitable evaluation parameters are investigated to analyze the effects of multiple factors on short-arc angles-only initial orbit determination.

Initial Orbit Determination for Space Situational Awareness System using Triangulation Method

2022 International Conference on Electrical, Computer and Energy Technologies (ICECET), 2022
Optical measurements provide a simple approach for operators to track visible orbital bodies. While range measurements are lacking, two simultaneous observations can be used to determine the range between the body of interest to the corresponding ...

Correlation of Optical Observations of Earth-Orbiting Objects and Initial Orbit Determination

Journal of Guidance, Control, and Dynamics, 2012
For optical observations of Earth-orbiting objects, multiple observationsmust be combined to determine the orbit of the observed object.Whether two arbitrary tracks are of the same object, however, is generally unknown a priori, and solving this problem with traditional approaches requires iterative procedures that do not guarantee convergence.

Initial Orbit Determination Results for Jason-1: Towards a 1 cm Orbit

Navigation, 2003
The U.S/France Jason-1 oceanographic mission is carrying state-of-the-art radiometric tracking systems (GPS and Doris) to support precise orbit determination (POD) requirements. The performance of the systems is strongly reflected in the early POD results.

Initial orbit determination results for the LARES satellite [PDF]

, 2012
LARES (LAser RElativity Satellite) is a laser-ranged satellite deployed by the Italian Space Agency (ASI). It is a spherical satellite covered with 92 retro-reflectors with a radius of 182 mm. Made of tungsten alloy, its weight is 386.8 kg, making it likely the highest mean density body in the Solar System.
