On the Mitigation of Solar Index Variability for High Precision Orbit Determination in Low Earth Orbit
Effective satellite mission operations are directly impacted by the ability to generate accurate and precise orbit predictions. High precision orbit determination processes rely on detailed force models to propagate an orbit solution and predict future orbit behavior. While gravity forces are typically well understood, the modeling of non-conservative forces is often more challenging, causing i...
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 کاملHigh-precision Onboard Orbit Determination for Small Satellites – the Gps-based Xns on X-sat
X-SAT is a mini-satellite developed by the Satellite Engineering Centre of the Nanyang Technological University at Singapore. The focus of the technologydriven mission is the high-resolution remote sensing of the Southeast Asian region for environmental monitoring. To achieve the ambitious mission objectives, the GPS-based X-SAT Navigation System (XNS) will provide high-precision onboard orbit ...
متن کاملThe Development of Automated Processing of Orbit Predictions for CHAMP
The German research satellite CHAMP, launched on July 15, 2000, features two tracking systems: a GPS Black Jack flight receiver and a Laser Retro Reflector (LRR). For operating the ground station network of the International Laser Ranging Service (ILRS) orbit predictions are needed. In order to meet the accuracy requirements of the SLR technique orbit predictions for CHAMP are generated at 12-h...
متن کاملreal-time hybrid orbit determination using satellite to satellite tracking observations
three-dimensional position measurements by global positioning system (gps) provide purely geometrical estimate of low earth orbiters (leos) positions. it provides uninterrupted tracking of the leos in three spatial dimensions or the so-called kinematic orbit. this solution relies heavily on the observations. high frequency observation noise, outlying observations and low redundancy number of me...
