WitrynaThe algorithms are developed for the same, the readings of different satellites in different orbits are considered and results are compared The results show that, Herrick-Gibbs method works better in LEO, Gibbs method works better for molniya orbits and Herrick-Gibbs and the Gauss method is suitable for GEO depending on arc length at a ... WitrynaHerrick-Gibbs Method When the track lengths between the position vectors are very small, the three vectors are almost parallel, so observation errors will likely degrade … WitrynaGibbs’ method is a geometric approach while Herrick–Gibbs essentially represents a series expansion. Therefore, the Herrick–Gibbs algorithm is the best for measurement separations around 1 ∘ or less, while Gibbs’ method is used for larger angular separations as stated in .

Witrynaelement set is obtained by first performing an initial orbit determination using the Herrick-Gibbs. 2. algorithm for each track of observations followed by a Simplified General Perturbations 4 (SGP4) DC to refine the element set. Because each GP element set in Figure 3 is created from only one track of Witrynaand Herrick-Gibbs methods, nonlinear batch least square and unscented Kalman filter is also pre-sented and its efficiency is investigated. In the following the observation method and mathematical models are given first. Then, esti-mation algorithms used are presented. Simulation results are given and discussed next. Finally, conclusions are …
