It’s a technology which has been donning our skylines for decades now, yet it can still be said that GPS for car tech has plenty of myths surrounding it. In short, the reason behind this is because it is widely misunderstood and through the course of today’s post, we will take a look at these devices in more detail to see just which misconceptions need debunking for good.
Myth #1 – The government tracks civilians with GPS devices
As everyone knows, we all love a good government conspiracy theory. Unfortunately, this one is plainly wrong – at least in most cases.
In an ideal world for the authorities, it would be possible to track each and every person. However, there’s a slight problem with this; most devices that take advantage of GPS technology are only capable of receiving signals. In other words, they are not able to relay this location information back to anyone, let alone the government. Even if they wanted to find out the whereabouts of people, it’s impossible with the majority of devices that the public own.
Myth #2 – Your GPS receiver won’t function properly if it’s cloudy
There is at least an apparent reason why this myth is so commonplace. As anyone who has watched satellite TV in bad weather will testify, it tends to take a turn for the unreliable on these occasions. Fortunately, GPS technology doesn’t follow the same principles. It’s actually based on a completely different type of signal. Sure, these signals are going to be affected if there is anything getting in the way of them, but luckily for most people this doesn’t involve clouds. Instead, objects that could interfere with them include buildings and mountains. In other words, dense materials.
Myth #3 – You should always rely on your GPS to find the best route
If only this were the case. Some companies are devising programs that can overlay traffic information with GPS signals, but until you find a reliable one of these there is never a guarantee that GPS device is going to find the best route for you.
Instead, it’s probably going to find the shortest route – but this isn’t necessarily going to be the fastest for you. Of course, in finding the shortest route it also needs to take into account the roads – you can’t rely on the information being as the crow flies.
Myth #4 – A military GPS signal is better than what civilians receive
The government have stated that this isn’t true, although there is a caveat. One of the reasons a lot of people think that the military GPS is more accurate is because they rely on two signals. These two signals come from the exact location as where civilians receive there from, but the difference is that this time civilians have just one to go off. Ultimately, while it might seem better, both are tapping into the same ones from space.
