Why do I need a GPS navigation unit for my vehicle?
In today’s high-tech world of smartphones, you may ask yourself, “Do I really need a GPS for my car?” While cell phones can help you get around, they simply don’t replace the anywhere-you-want-to-go capabilities of GPS navigation units.
The biggest advantage of navigating with a GPS instead of a cell phone is GPS navigation units don’t rely on a cellular signal to get you to your location. Instead, they use a system of 30 satellites that continuously orbit Earth. Each of these frequently emits information about its location back to Earth at the speed of light, and no matter where you’re at on the planet or what time of day it is, your GPS is able to receive this information from at least four of them. Your GPS then calculates how far you are from each satellite and pinpoints your location based on that information. This means that no matter where you are, you’ll always be able to get directions to where you need to be. And because GPS units don’t rely on costly cellular data plans to receive their information, you can use one all day, seven days a week, and you won’t be charged a penny more.
