The LEO satellite's Position, Velocity, and Time (PVT) information leverages the known position of a mobile device containing the LEO satellite's ground satellite receiver, and the LEO satellite's range information (range and/or It can be determined by using the range rate). According to ...
PURPOSE: To prevent the unstable coding operations of a highly efficient code decoder and also to eliminate the click noises generated from the code decoder despite execution of the voice activation in regard of a velocity converting circuit of a satellite communication receiver which carries out the...
After an overview of approaches and results in precise orbit determination (POD) for the CHAMP satellite in the Low Earth Orbit (LEO) we focus on the relations between kinematic POD and gravity field determination. We discuss determination of kinematic velocities out of kinematic positions that ...
In obserations of the Earth s atmosphere with the GPS radio occultation technique,some factors such as the position error of GPS and LEO satellite,velocity error,clock drift,and observation error of carrier wave can bring error to the retrieval atmospheric parameters. 在无线电GPS大气掩星观测中,...
the bulk ion population interacts with waves through cyclotron resonance based on the mass. The Freja satellite observed core ion (<20 eV) bulk heating without any apparent tail-heating feature26,27. Sometimes, a fraction of the ion population in the tail near the wave-phase velocity is res...

The Effect of Angular Velocity on Inter-Satellite Links in LEO Satellite NetworksSidibeh, K.Vladimirova, T.International Review of Physics
The theoretical aspects of the precise velocity determination of Low Earth Orbit (LEO) satellites'on board Global Navigation Satellite Systems (GNSS) receivers are derived. It shows that the receiver's Phase Lock Loop (PLL) is required to feature extremely small group delay within its low ...
The multiple model adaptive control approach is employed to counteract large uncertainty in parameter space of the inertia matrix. The nonlinear dynamics of a low earth orbit satellite is simulated and the proposed control algorithm is implemented. The reported results show the effectiveness of the ...
