Tundra orbit - Wikipedia
A Tundra orbit (Russian: орбита «Тундра») is a highly elliptical geosynchronous orbit with a high inclination (approximately 63.4°), an orbital period of one sidereal day, and a typical eccentricity between 0.2 and 0.3.
orbital mechanics - Difference between Tundra and Molniya …
2018年1月3日 · Tundra is intended for a single satellite to observe one specific point of Earth. Molniya is an orbit intended for 3-satellite constellations and it has a period of half a day. It's also used to observe two off-equator regions of Earth, 180 degrees of longitude apart.
Geosynchronous orbit - Wikipedia
A geosynchronous orbit (sometimes abbreviated GSO) is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds (one sidereal day).
What are the advantages of a Molniya orbit over a tundra orbit?
2018年11月26日 · The high apogee of a Tundra orbit will give you lower resultant signal power, but you'll both have clearer line of sight to a larger audience (the satellites will appear higher from the horizon for a larger population) and a longer dwell time above that audience.
Tundra orbits - (Engineering Mechanics – Dynamics) - Fiveable
Tundra orbits allow satellites to pass over high-latitude regions, making them ideal for observing the Arctic and Antarctic areas. The inclination of 63.4 degrees in tundra orbits provides a balance between coverage of polar regions and operational efficiency.
Highly elliptical orbit - Wikipedia
A highly elliptical orbit (HEO) is an elliptic orbit with high eccentricity, usually referring to one around Earth. Examples of inclined HEO orbits include Molniya orbits, named after the Molniya Soviet communication satellites which used them, and Tundra orbits.
Tundra orbit - Wikiwand
A Tundra orbit ( Russian: орбита «Тундра») is a highly elliptical geosynchronous orbit with a high inclination (approximately 63.4°), an orbital period of one sidereal day, and a typical eccentricity between 0.2 and 0.3.
Tundra Disposal Orbit Study | ESA Proceedings Database
From a debris mitigation perspective, this makes the use of Tundra orbits more attractive than the use of GEO orbits. This paper presents a detailed study of Tundra disposal orbits. Long-term propagations were performed using the precision integration code TRACE.
Tundra orbit for high latitudes and polar regions, as a possible candidate to fill the data gap left by GEO. The Tundra orbit is uniquely different from GEO and LEO and is characterized by three key features [7]: geosynchronous period, nonzero inclination angle, and nonzero orbital eccentricity. The long
The Three Defining Characteristics for Outer Space Orbit
2019年4月21日 · Essentially a highly elliptical Geosynchronous Orbit (covered in the upcoming High Earth Orbit section), Tundra orbits have an apogee of 46,990 km above sea level and a perigee of 23,980 km above sea level.
