The Apsidal Precession for Low Earth Sun Synchronized Orbits
By nodal regression and apsidal precession, the Earth flattering at satellite low Earth orbits (LEO) is manifested. Nodal regression refers to the shift of the orbit’s line of nodes over time as Earth revolves around the Sun. Nodal regression is orbit feature utilized for circular orbits to be Sun synchronized. A sun-synchronized orbit lies in a plane that maintains a fixed angle with respect t...
متن کاملThe Inclination Window for Low Earth Sun Synchronized Satellite Orbits
Generally, circular orbits of satellites are categorized as Geosynchronous Earth Orbits (GEO), Medium Earth Orbits (MEO) and Low Earth Orbits (LEO). The main difference between them is their attitude above the Earth’s surface (Richharia, 1999; Roddy, 2006; Maral and Bousquet, 2002). The Sun synchronization feature is typical for LEOs. Sun synchronized low Earth orbits have a very wide applicati...
متن کاملPrecise 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 کاملAn Analytical Solution for Relative Motion of Satellites
An analytical solution to the relative motion of satellites in eccentric orbits, under the effects of the nonlinearity of the gravitational field and the 2 J -perturbation, is presented. The most notable feature of the solution is the use of the unit sphere for the description of the motion. Solutions to the relative motion coordinates and velocities are obtained by using a geometric approach, ...
متن کاملGPS Phase-Connected, Precise Point Positioning of Low Earth Orbiters
A completely geometric approach for precise orbit determination (POD) of low earth orbiter (LEO) spacecraft has been devised by the authors which does not use dynamic models, but only data from the GPS receiver onboard the LEO and the International GPS Service (IGS) precise GPS ephemeris product. The strategy relies on combining the time-continuous measurement strength of the pseudorange and ca...
