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.

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

Scientific 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

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 ...
