Multi-Observations Initial Orbit Determination based on Angle-Only Measurements
A new approach with the ability to use the multiple observations based on the least square approach has been proposed for initial orbit determination. This approach considers the Earth’s Oblateness by using the developed Lagrange coefficients. The efficiency of the proposed method has been tested in two scenarios. The first scenario is to use the simulated and the second one is to utilize the r...

متن کاملDetermination of the best-fitting reference orbit for a LEO satellite using the Lagrange coefficients
Linearization of the nonlinear equations and iterative solution is the most well-known scheme in many engineering problems. For geodetic applications of the LEO satellites, e.g. the Earth’s gravity field recovery, one needs to provide an initial guess of the satellite location or the so-called reference orbit. Numerical integration can be utilized for generating the reference orbit if a satelli...
متن کاملPrecise orbit determination of BeiDou constellation based on BETS and MGEX network
Chinese BeiDou Navigation Satellite System is officially operational as a regional constellation with five Geostationary Earth Orbit (GEO) satellites, five Inclined Geosynchronous Satellite Orbit (IGSO) satellites and four Medium Earth Orbit (MEO) satellites. Observations from the BeiDou Experimental Tracking Stations (BETS) and the IGS Multi-GNSS Experiment (MGEX) network from 1 January to 31 ...
متن کاملThe Use of Short-arc Angle and Angle Rate Data for Deep-space Initial Orbit Determination and Track Association
The population of deep space resident space objects (RSOs) are tracked with sparse resources and thus tracking data are only collected on these objects for a relatively small fraction of their orbit revolution (i.e. a short-arc). This contributes to commonly mistagged or uncorrelated RSOs, and their associated trajectory uncertainties (covariances) to be less physically meaningful. The case of ...
