Precise Orbit Determination for Low Earth Orbit Satellites
The precise orbit determination problem is to accurately determine the position and velocity vectors of an orbiting satellite. In this paper we review the general contents of the orbit determination process, with particular emphasis on Low Earth Orbit (LEO) satellites. The different orbit determination approaches and the different force models contained within are briefly discussed. The two mai...
متن کاملOn 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 کاملLow-Earth Orbit Determination from Gravity Gradient Measurements
An innovative orbit determination method which makes use of gravity gradients for Low-Earth-Orbiting satellites is proposed. The measurement principle of gravity gradiometry is briefly reviewed and the sources of measurement error are analyzed. An adaptive hybrid least squares batch filter based on linearization of the orbital equation and unscented transformation of the measurement equation is...
متن کاملSpace Radiation Effects on Electronic Components in Low-earth Orbit
Space Radiation Environment, Essential Basics: Radiation in Space is generated by particles emitted from a variety of sources both within and beyond our solar system. Radiation effects from these particles can not only cause degradation, but can also cause failure of the electronic and electrical systems in space vehicles or satellites. Even high altitude commercial airliners flying polar route...

approach even when there were unambiguous perspective cues to retreat. Conversely, the mean of the function fitted to judgements of the female walker is below the neutral point, consistent with female walkers appearing to retreat even when there were unambiguous perspective cues to approach. These effects were independent of observer gender. The results demonstrate that the perceived direction-...
