Uncertainty Analysis of the Short-Arc Initial Orbit Determination [PDF]

open access: yesIEEE Access, 2020
The solution of the short-arc angles-only orbit determination problem has large uncertainty because the topocentric range is not observable. For a certain angular observation tracklet with measurement noise, there exist numerous potential orbits, all of ...

Improved Initial Orbit Determination Based on the Gooding Method of Low Earth Orbit Space Debris Using Space-Based Observations

open access: yesRemote Sensing, 2023
Initial orbit determination (IOD), as a basis for initial orbit association and accurate orbit determination (OD), has a crucial role in the process of obtaining space debris orbit information. Among the traditional methods, the Gooding method has better

Coarse Initial Orbit Determination for a Geostationary Satellite Using Single-Epoch GPS Measurements [PDF]

open access: yesSensors, 2015
A practical algorithm is proposed for determining the orbit of a geostationary orbit (GEO) satellite using single-epoch measurements from a Global Positioning System (GPS) receiver under the sparse visibility of the GPS satellites.

Uncertainty analysis of initial orbit determination in the minimum radar admissible region [PDF]

open access: yesScientific Reports
The 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

Initial Orbit Determination and Event Reconstruction From Estimation of Particle Trajectories About (101955) Bennu [PDF]

open access: yesEarth and Space Science, 2020
The OSIRIS‐REx mission has observed multiple instances of particles being ejected from the surface of near‐Earth asteroid (101955) Bennu. The ability to quickly identify the particle trajectories and origins is necessary following a particle ejection ...

Initial orbit determination of BDS-3 satellites based on new code signals

open access: yesGeodesy 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 Optical and Radar Initial Orbit Determination

open access: yesJournal of Guidance, Control, and Dynamics, 2018
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

open access: yesRemote 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.

Generalization of a method by Mossotti for initial orbit determination [PDF]

open access: yesCelestial Mechanics and Dynamical Astronomy, 2021
AbstractHere, we revisit an initial orbit determination method introduced by O. F. Mossotti employing four geocentric sky-plane observations and a linear equation to compute the angular momentum of the observed body. We then extend the method to topocentric observations, yielding a quadratic equation for the angular momentum. The performance of the two
