Introduction
Global Positioning System (GPS) Receivers and Transmitters
GPS and Navigation
I work on and with GPS’s every day, so to look further into how GPS receivers and transmitters work will help me within my military career.
Body
Global Positioning Systems are equipment used around the world and in space to provide users with positioning, navigating, and timing services.
GPS services were developed during the Sputnik era. Scientist were able to track a satellite with shifts in the radio signal, known as the “dobbler effect”. It was generally created for the military. The Navy was the first to use the experiment in the mid 1960’s so they could try to track their submarines. The Department of Defense (DoD) finally launched their own navigation satellite known as the Navigation System with Timing and Raging (NAVSTAR). GPS became fully operational years later in 1993.
Commercial and military currently use GPS in our everyday lives. Whether its to see where certain equipment is or to see how far your mom’s house is from where you currently are.
How the technology works
The GPS does not transform any type of energy into anything.
Within the GPS, there are receivers and transmitters. First you turn the GPS on. Then the transmitter connects to a satellite that is in space, there are currently 24 satellites it can connect to for the U.S. At which, the receiver receives signal transmissions from the satellite to show you exactly where you are or where an object is.
Enabling technologies would be the 24 satellites that is orbiting around space.
Scientist are trying to modernize GPS’s. They are upgrading the features by getting new civilian and military GPS signals.
Conclusion
Global Positioning Systems are the most known and trusted devices to find any and everything that could be tracked, whether it is you, a place or an object.
GPS has receivers and transmitters that connects to one of the 24 satellites that orbit around Earth. It was originally created for the military to track their equipment. Since then, GPS has been branched out to be used by everyone including civilians. It is evolving as we speak, as scientist try to upgrade the systems with new signals for both military and commercial use.
