GPS is considered to be one of the most genius inventions known to man. Could you imagine a world that didn’t have an online map? We would be confined to the only things, or in this case places, that we know, and fail to learn about the areas around us, unless we explored the traditional map, without knowing for sure whether we’re going in the right direction.
It’s safe to say, that GPS has only improved the lives of people, and businesses, around the world. Today, in most cases, people cannot even travel to the other side of town without it, unless they know where exactly they’re going that is.
The GPS was designed, along with the sea-going chronometer, which was has a similar purpose to GPS, except for the fact that it helps one navigate the ocean, instead of navigating the land.
What is GPS?
GPS stands for a global positioning system. It is a navigation system, which is satellite-based and consists of 24 orbiting satellites, which makes up a network. This network of satellites spans to up to eleven thousand nautical miles in within six unique orbital parts, in space. With only two of these 2 of these orbits surrounding earth and circles the entire surface thereof in less than 24 hours. It thus moves at 2.6 kilometres per second, which is faster than any transportation that earth will ever have.
GPS is also referred to as NAVSTAR satellites. The first satellite of NAVSTAR was launched in 1978, which was before the mere idea of the internet even existed.
Each satellite has a transmitter power of up to 50 watts and transmits on three different frequencies and are built to last at least a decade, before having to be replaced with a better technological enhanced satellite.
The pathways of these satellites can transport them 60 degrees North, as well as 60 degrees South, in latitude. This mere setting allows one to be able to receive signal nearly anywhere in the world and at any time too. The fact that satellites are not above your location is the number one reason why your signal might be affected, especially in underdeveloped areas.
The Evolution of Technology for GPS
GPS was invented after understanding came about for the electromagnetic energy, known as the radio. Before the invention of the radio, ships and aircraft travelled at their own risk, not acknowledging the dangers of what it’s like to travel without a source of support in the air or somewhere far away from land, at sea.
Once the radio was developed in the 1920’s, it accumulated a massive amount of money for those who invented it and continued to work on increasing it as the digital age got closer and closer. When GPS was discovered in the late 70’s, however, the world turned a page and found a new way to get around easily and with satellites lined up around the world, made it extremely effective and easy to not get lost ever again.
