WebA highly elliptical orbit (HEO) is an elliptic orbit with high eccentricity, usually referring to one around Earth. Examples of inclined HEO orbits … A typical Molniya orbit has the following properties: Argument of perigee: 270°Inclination: 63.4° Period: 718 minutes Eccentricity: 0.74Semi-major axis: 26,600 km (16,500 mi) Argument of perigee The argument of perigee is set at 270°, causing the satellite to experience apogee at the most northerly point of its … See more A Molniya orbit is a type of satellite orbit designed to provide communications and remote sensing coverage over high latitudes. It is a highly elliptical orbit with an inclination of 63.4 degrees, an argument of perigee of … See more Much of the area of the former Soviet Union, and Russia in particular, is located at high northern latitudes. To broadcast to these latitudes from a geostationary orbit (above the Earth's See more • List of orbits • Tundra orbit See more The Molniya orbit was discovered by Soviet scientists in the 1960s as a high-latitude communications alternative to geostationary orbits, … See more To track satellites using Molniya orbits, scientists use the SDP4 simplified perturbations model, which calculates the location of a satellite based on orbital shape, drag, … See more • Illustration of the communication geometry provided by satellites in 12-hour Molniya orbits (video) See more

WebAug 17, 2024 · Instead of 35,786 kilometers above the Earth’s surface, semi-synchronous orbits are approximately 20,200 kilometers above the surface. This puts them in the medium Earth orbit range out of the three classes of orbits. These orbits are close to zero in eccentricity, meaning they are near-circular. Eccentric orbits define how stretched orbits … WebJun 22, 2024 · The Molniya orbit combines high inclination (63.4°) with high eccentricity (0.722) to maximize viewing time over high latitudes. Each orbit lasts 12 hours, so the slow, high-altitude portion of the orbit repeats over the same location every day and night. st joseph\u0027s and st anne\u0027s catholic community
