Global Positioning System (GPS)

Previously, we already talked about Geo-Stationary Satellite and what its purposes. Now, we will look at one of the technology used by the satellite. It is called 'Global Positioning System'. Let say when you are traveling to somewhere unfamiliar, and you do not know where exactly you are and is it the correctly heading you took? Well, introducing to Global Positioning System (GPS) that will help you to navigate and notify what is your current location. This kind of technology created to ease-up the humankind especially for travelers. The GPS becomes famous nowdays and some of you might be take it as a requirement for life.

Space Technology: Sun-Synchronous Satellite

Sun-Synchronous Satellite is one of the satellites that moving around the earth and always gets its power source from the sun. It also called a geo-centric which includes altitude and inclination measurement. Due to the satellite is always keeps moving on, so in 24 hours the satellite will pass few countries at the same local solar system (to get solar power from the sun). And this is of course the complete one year of the satellite oscillation, is the direct correlation with actual solar time.

For a geo-stationary satellite, we all know that the purposes are for communication, coordination, TV broadcasting and earth observation. In sun-synchronous satellite case the purpose are mostly for the military and remote sensing. This kind of satellite we can use it for spying other countries.

Space Technology: Geo-Stationary Satellite

A Geo-Stationary Satellite (also known as Geo-Synchronous Satellite) is one of the satellite types which positioned straight on top of the equator (earth surface) accurately 22,300 miles out in space. With this particular distance, the satellite must take a full 24 hours to complete a circle together with earth. The tricky practice here is to make sure that the satellite has to move along with earth wherever it goes. In other word, a geo-stationary satellite has to remain in the same mark on earth. The animation picture below might help out to get a better understanding about the movement of geo-stationary satellite.
