Nowadays, there’s no excuse for getting lost. Our smartphones already come with decent mapping and navigation aids that get us through the day. Nothing beats a dedicated GPS unit when it comes to truly accurate and dependable satellite navigation. If you’re looking to get one, this is the guide to help you. From INS simulation to manufacturer support, here are the things to look for to ensure that you’re investing your money smartly.
1. Look for true satellite coverage.
A word on the basics: GPS units need a minimum of four solid satellite connections to function optimally. The four combine to provide accurate positional information. Better GPS units either leverage more satellite or provide for smoother handoff when moving through different coverage locations. It might cost more to get a unit that is this accurate, but it’s certainly worth the investment if accuracy is critical to your daily life.
2. Get those with test simulators.
GPS relies on a range of technologies to operate properly. One of the most important is the Inertial Navigation System (INS). This is what allows your unit to compute for proper trajectories as you move along your way. An in-built INS simulation apparatus allows you to test your unit’s capabilities without needing to put yourself at any risk whatsoever. This allows you to have updates on the capabilities of your unit at any time you have doubts to ensure that it’s always working well.
3. Bank on manufacturer support.
The world is constantly evolving. Whether navigating through the air or on the roads, things change — from the active airways to the road regulations. To stay on top of things, you rely on updates pushed to your system by the manufacturer of your device. It’s important to check on the timeliness and consistency of their updates. It can make a difference when it comes to the longevity of your unit.
With these three things considered, it should be an easy thing to do. A GPS unit can be an invaluable tool for a lifetime if chosen properly.
