Web6 okt. 2024 · Velocity of GPS Satellites Global Positioning System (GPS) satellites travel approximately 14,000 km/hour, relative to the Earth as a whole, as opposed to relative to a fixed point on its surface. The six orbits are tipped at 55° from the equator, with four satellites per orbit (see diagram).

Orbital speed - Wikipedia
The mean orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s (4.8 mi/s), which translates to 28,000 km/h (17,000 mph). However, this depends on the exact altitude of the orbit. Calculated for a circular orbit of 200 km (120 mi) the orbital velocity is 7.79 km/s (4.84 mi/s), but for a higher 1,500 km (930 mi) orbit the velocity is reduced to 7.12 km/s (4.42 mi/s). The launch vehicle's delta-v needed to achieve low Earth orbit starts around 9.4 km/s (5.8 mi/s). WebTo stay in orbit, a satellite has to travel at a very high velocity, which depends on the height. So, typically, for a circular orbit at a height of 300 km above the Earth’s surface, a speed of 7.8 km/s (28,000 km/h) is needed. At this speed, the satellite will complete one orbit around the Earth in 90 minutes. WebThe orbit period, mainly depending on the altitude, varies in the range 90–120 min. As the altitude of LEO satellites is low, their velocity is very high (>25,000 km/h) and they make … razor onclick
