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

Probabilistic Optical and Radar Initial Orbit Determination [PDF]
Journal 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

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