To find the orbital velocity of an artificial satellite revolving around the Earth at a height of 100 km, we can follow these steps: Step 1: Understand the Formula for Orbital VelocityThe formula for the orbital velocity v of a satellite is given by: v=√GMr where:- G is the gravitation...
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 ...
Velocity is a vector quantity that denotes “the rate at which an item changes location.” Consider a person who takes one step forward and one step back at a quick pace, constantly returning to the same starting place. While this would cause a flurry of activity, it would also result in...
Equations (1) to (5) show clearly that the orbital speed or the time period of a satellite does not depend on the mass of the satellite at all. It should be mentioned that, if the orbit of a satellite is an ellipse of eccentricity e, the highest and the lowest orbital speed will be...
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...
Students at the ETH Zurich have produced a prototype driverless race car to compete in “Formula Student” competitions in Europe. Advanced Global Navigation Satellite System (GNSS) modules and antennas from Hexagon | NovAtel® are helping make the vehicle one of the very best in its class. Le...

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...
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...
commercial satellite bus to rely on ion propulsion for GEO station keeping. While ion engines compete well with other EP options for near-earth applications, their ability to operate efficiently and reliably at even higher exhaust velocities makes them ideally suited for energetic (i.e., high Δ...
