Certain studies mention a global trend of increasing values in wind speed, like the recent one ofYoung et al. (2011)focusing on oceanic wind speeds based on a 23-year database of calibrated and validatedsatellite altimetermeasurements, or that ofTroccoli et al. (2012)concentrating on the Aust...
The new formulae have been numerically tested and analysed by comparison with the precise SP3 ephemeris, and the velocity and acceleration derived by the satellite positions obtained from the broadcast ephemeris respectively. A practical algorithm for ECEF velocity and acceleration determination is then ...
Space-borne Precipitation Radar (SPR) is an active measurement radar used on a satellite platform that can observe rainfall characteristics in all weather conditions at all times with three-dimensional (3D) detection in the range of the radar observation. SPR is the only effective tool that direct...

The formula can be easily derived from Newton's gravitation force formula and centrifugal force formula: m -object mass (excluded, during evaluation of v1) Two and half centuries later, after Newton's discoveries, in 1957, USSR launched the Earth's first artificial satellite. R-7 carrier rock...
This formula works just as well if R is at the radius of an aircraft as it would if R was at the radius of a satellite (and indeed the two radii only differ by a few km for a satellite in low Earth orbit)--for example, a craft 863 meters above the surface at the equator would...
Circumbinary planets, those that orbit around both stars of a central binary star system, challenge our understanding of planet formation. With only 12 binary systems known to host circumbinary planets, identifying more of these planets, along with their physical properties, could help to discern som...
It goes up to a height h before returning to earth. At height h a body is thrown from the rocket with speed υ0 in such away so that the body becomes a satellite of earth. Let the mass of the earth, M=6×1024kg, mean radius of the earth, R=6.4×106m,G=6.67×10−11Nm2kg...
The escape velocity of any object is the minimum speed required to move out from the gravitational field of any massive body. The escape velocity of the object is dependent on Mass of the object Distance of the object from the center of mass of the body. The formula of escape velocity ...
Importance Of Tangential Velocity Tangential velocity can be observed in many cases, including any nonlinear motion, such as the abrupt jump from a swing or the deviation of a satellite or the Earth itself from its circular orbit. The circular motion of a satellite or our Earth occurs in anoc...
