Explore satellite orbits. Learn the definition of a satellite orbit and understand the types of orbits of satellites around Earth. See how fast satellites travel. What are Satellite Orbits? Asatelliteis a body or object in space that orbits around a larger body, such as a planet. This object...
We say that a planet is Earth-like if the coefficient of the second order zonal harmonic dominates all other coefficients in the gravity field. This paper concerns the zonal problem for satellites around an Earth-like planet, all other perturbations excluded. The potential contains all zonal ...

From communication to precision farming, different types of satellites are tailored to different needs. Their orbital heights also vary from mission to mission.
Ordinary Earth satellites are usually placed into five categories of special orbits: sun-synchronous orbits, orbits at the critical inclination, frozen orbits, repeating ground track orbits, and geostationary orbits. This paper investigates their counterparts around Mars and examines the basic nature of ...
designing low-cost constellations that save money by placing a small number of satellites around the Earth at relatively low altitudes, said William Crossley, an associate professor at Purdue's School of Aeronautics and Astronautics and a faculty member of the university's Center for Satellite ...
