Instant Active Positioning with One LEO Satellite
Autonomous position determination in the Globalstar satellite communication system is discussed. ( ) The two-way communication between a user terminal on the earth’s surface and a single low earth orbit LEO satellite makes it possible to derive range and range-rate and determine the user terminal position instantly. Expected accuracy is presented, and a simple direct solution is given. INTRODUC...
متن کاملOrbital Perturbation Effect on LEO Satellite Trajectory
A satellite, in its orbit, is affected by perturbing forces, such as atmospheric drag, solar radiation pressure, Earth oblateness, and gravity of the celestial masses (other than the Earth). In this paper, the effects of these forces on the trajectories of different types of LEO satellites and a sample satellite (Z-SAT) are discussed. A few analyses are done on these orbits and the relevant res...
متن کاملEstimation of LEO Satellite
In this paper, we propose a new channel estimation algorithm for low earth orbit satellite digital communications. Low earth orbit satellite channels impart severe spreading in delay and Doppler on the transmitted signal. We model the channel as a tapped-delay-line lter with time-varying complex coeecients. The time evolution of the taps is described by an auto-regressive model. A coupled lter ...

متن کاملInternet Routing over LEO Satellite Constellations
Satellite constellations ooer interesting perspectives for Internet traac routing, since they beneet from a worldwide coverage and do not have the main drawback of geosynchronous satellites : propagation delay. However, because of their low altitude, LEO satellites are in constant motion and exhibit speciic issues for routing. This article presents a general architecture applicable to the integ...
