Currently, data from the US Space Force’s Space Based Space Surveillance satellite system. And the European Space Agency (ESA) states that there are no less than 29,000 objects, including spacecraft, space stations, rocket parts, and working satellites. and horoscopes that can no longer be used They are more than 10 centimeters in size and are orbiting the Earth at different heights.
for the orbits of satellites and spacecraft will be sent into different orbits according to the objectives and goals of that mission, consisting of Near-Earth orbit or Low Earth Orbit at the International Space Station. The Tiangong space station, Hubble telescope and THEOS-2 satellite all orbit. It is an orbital height between 160-2,000 kilometers from the earth. Suitable for human spaceflight. including earth observation satellites communication satellite and astronomical studies, etc.
The next orbit is a medium orbit or Medium Earth Orbit at an altitude between 2,000-35,786 kilometers or between orbits close to Earth. and geostationary orbit It is usually the orbit of the navigation satellite network. communication satellite and some earth observation satellites, for example the GPS, Galileo, and BeiDou navigation satellite networks or the OneWeb communications satellite network, etc.
For geostationary orbit, it is the orbit of satellites that are 35,786 kilometers above the Earth’s equator. whose orbital period corresponds exactly to the Earth’s rotational rate. Makes it seem like you are in a ‘fixed point’ all the time, which is usually the orbit of a communication satellite. weather satellite and navigation satellites, etc.
Another orbit that is similar to a geostationary orbit is the Geosynchronous Orbit, which is also at an altitude of 35,786 kilometers. It’s just that they don’t have to orbit above the Earth’s equator.
Information in the above These are just some of the different types of orbits that satellites and spacecraft station around our planet. It also has an orbital type. Sun-synchronous Orbit, Polar Orbit, Highly Elliptical Orbit, or orbit around Lagrange Points between the Earth and the Sun. Some orbits may have different eclipses, which the word Apogee is used to refer to at distant points. The closest point of the orbit and Perigee is used to refer to the closest point of the orbit.
With the trend of having more and more objects in orbit continuously. Make the Office of Space and Geo-Informatics Technology Development (Public Organization) or GISTDA has developed a space traffic management system named ZIRCON to monitor and warn of the risk of collisions between space objects. with the Thaichote satellites, THEOS-2, and THEOS-2A, as well as extending services to other satellite operators who are interested. ZIRCON is a system developed and invented by all Thai personnel. and has started providing information services since 2022.
