Solve questions about how satellites are located in space and what you should know about their orbital positions.

Currently, the data is from the US Space Force's Space Surveillance Satellite System. The European Space Agency (ESA) states that there are at least 29,000 objects, including spacecraft, space stations, rocket parts and operational satellites. The towers, which can no longer be used, are more than 10 centimeters in size and orbit around the Earth at different heights.

For orbits, satellites and spacecraft will be sent to different orbits according to the goals and objectives of that mission, consisting of near-Earth orbit or low-Earth orbit at the International Space Station. The Tiangong Space Station, the Hubble Telescope, and the THEOS-2 satellite all orbit. Its orbital altitude ranges between 160-2000 kilometers above Earth. Suitable for human spaceflight. Including Earth observation satellites, communications satellites, astronomical studies, and others.

The next orbit is a medium orbit or medium Earth orbit at an altitude ranging between 2000-35,786 kilometers or between near-Earth orbits. The geostationary orbit is usually the satellite navigation orbit. Communications satellite and some Earth observation satellites, for example GPS navigation satellite networks, Galileo, BeiDou or OneWeb communications satellite network, etc.

For geostationary orbit, it is the orbit of a satellite located at an altitude of 35,786 kilometers above the Earth's equator. Its orbital period corresponds exactly with the Earth's rotation rate. It makes it appear as if you are at a “fixed point” the entire time, which is usually the orbit of a communications satellite. Weather satellite, navigation satellite, etc.

Another orbit similar to the geostationary orbit is the geosynchronous orbit, which is also located at an altitude of 35,786 km. It's just that they don't have to orbit above the Earth's equator.

The information above is just some of the different types of orbits that satellites and spacecraft place around our planet. It also has an orbital type. A sun-synchronous orbit, a polar orbit, a highly elliptical orbit, or an orbit around Lagrange points between the Earth and the Sun. Some orbits may have different eclipses, for which the word apogee is used to refer to distant points. Perigee is used to indicate the closest point to the orbit.

With the trend of having more and more objects in orbit continuously. Establishment of the Space and Geoinformatics Technology Development Office (public institution) or GISTDA developed a space traffic management system called ZIRCON to monitor and warn of the dangers of collisions between space objects. With the Thaichote, THEOS-2, and THEOS-2A satellites, in addition to providing services to other interested satellite operators. ZIRCON is a system developed and invented by all Thai employees. It began providing information services since 2022.
