WebJan 2, 2024 · Orbital: Tundra: 1 satellite, 1 day period, 0.2 to 0.3 eccentricity. Molniya: 3 satellites, 12h period, 0.7 eccentricity, RAAN and True Anomaly spread 1/3 period apart. Functional: Tundra: observing one point of Earth, … WebA semi-synchronous orbit is an orbit with a period equal to half the average rotational period of the body being orbited, and in the same direction as that body's rotation. For Earth, a semi-synchronous orbit is considered a medium Earth orbit, with a … The Molniya orbit was discovered by Soviet scientists in the 1960s as a high-latitude communications alternative to geostationary orbits, which require large launch energies to achieve a high perigee and to change inclination to orbit over the equator (especially when launched from Russian latitudes). As a result, … 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 A typical Molniya orbit has the following properties: • Argument of perigee: 270° • Inclination: 63.4° See more • List of orbits • Tundra orbit See more • Illustration of the communication geometry provided by satellites in 12-hour Molniya orbits (video) 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 equator) requires considerable power due to the low elevation angles, … 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 tarotforempowerment
