Today we learnt about different forms of navigation and where they are used in transport and everyday life. Before we started studying, we had to travel to Picton via a QANTAS First Class flight! Once we arrived in Picton (which I might add, looks suspiciously similar to Auckland) we went on the LEARNZ website, where there are pages on different aspects of navigation. These pages contain information on how people use their instruments in their jobs to navigate on land, sea and air. We wrote notes in our inquiry books, then we took the quiz related to the subject we had been studying. We learnt how GPS systems can have effects on so many other things around the world. Some of which include, the stock market and ATM machines. GPS satellites have an atomic clock installed inside them that is accurate to one billionth of a second. If a GPS satellite thinks that it’s 12:01pm when it’s actually 12, it can completely miscalculate your position and tell you that you’re somewhere you’re not. By 2020, there is expected to be new satellites that will be accurate to a fraction of a billionth of a second. A GPS system has a connection with at least three GPS satellites. GPS stands for Global Positioning System. To use a GPS navigator, it is better to be in full view of the sky, this is because the system needs to have a direct view of the satellite, otherwise the signal will be weak. We are going to learn more about what it takes to use a GPS and GIS navigating systems, and what sorts of jobs require these skills.
