Then the satellite position of the adjacent time can be differentiated to obtain the satellite’s velocity. Then use the position and velocity information which is provided by the INS, and combine with data from an altimeter of the carrier, thereby we can obtain the elevation information. Then ...
Specifically, the fluid particle has the maximum velocity upstream of the meander (main axis), without shear and orbital vorticity. If the particle turns right in the meander, it gains clockwise orbital vorticity, which must be compensated by a counterclockwise shear vorticity of the same order. ...
➨Step-3: The second apogee motor firing is carried out so that satellite attains needed angular velocity and acceleration for Geo-synchronization. This helps satellite to be in LOS from central earth stations. If required it is tracked through other earth stations in its vicinity. ...
This is because the gravitational force from the earth decreases as the satellite moves further away, causing the satellite's speed to decrease. However, this decrease in speed is counteracted by the satellite's inertia, which causes it to maintain its orbital velocity. Can the speed of a ...
