Uphere.Space real time tracking and predictions. As soon as new satellites are launched this application begins tracking them. ISS Tracker, since 2015 the most popular ISS Tracker and passes list. Heavens-Above, called "the most popular website for tracking satellites" in 2007 by Sky and Telescope magazine and referenced by NASA websites.
A ground track or ground trace is the path on the surface of a planet directly below an aircraft 's or satellite 's trajectory. In the case of satellites, it is also known as a suborbital track or subsatellite track, and is the vertical projection of the satellite's orbit onto the surface of the Earth (or whatever body the satellite is orbiting ...
The United States Space Surveillance Network (SSN) detects, tracks, catalogs and identifies artificial objects orbiting Earth, e.g. active/inactive satellites, spent rocket bodies, or fragmentation debris. The system is the responsibility of United States Space Command and operated by the United States Space Force and its functions are:
The Tundra orbit is an eccentric geosynchronous orbit, which allows the satellite to spend most of its time dwelling over one high latitude location. It sits at an inclination of 63.4°, which is a frozen orbit, which reduces the need for stationkeeping. [23] At least two satellites are needed to provide continuous coverage over an area. [24]
As of July 2023, the website UCS Satellite Database lists 6,718 known satellites. Of these, 580 are listed in the database as being at GEO. The website provides a spreadsheet containing details of all the satellites, which can be downloaded. Listings are from west to east (decreasing longitude in the Western Hemisphere and increasing longitude ...
Satellites in geostationary orbit. A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.Such a satellite returns to the same position in the sky after each sidereal day, and over the course of a day traces out a path in the sky that is typically some form of analemma.
For natural satellites, which can attain a synchronous orbit only by tidally locking their parent body, it always goes in hand with synchronous rotation of the satellite. This is because the smaller body becomes tidally locked faster, and by the time a synchronous orbit is achieved, it has had a locked synchronous rotation for a long time already.
