The Global Positioning System (GPS) is a satellite-based radio navigation system that is used to determine the ground position of an object. Information derived from GPS can be utilized to craft accurate surveys and maps, take precise time measurements, and track position or location. Since its initial launch in 1978, the market for GPS devices has transformed, offering users handheld GPS options found in tablets, cellular phones, and more. In this blog, we will cover how to choose the right GPS device for your applications.
As GPS devices provide users with essential information regarding where you are, where you have been, and where you want to go, there are certain specifications to look for. Depending on the need at hand, it may be beneficial to opt out of GPS apps on your phone, and look to purchase stand-alone GPS units.
Beyond price, features, screen size, sonar capability, and portability, you must consider whether you need your GPS device to serve you in the case of an emergency or simply, as a compass. Some GPS devices only have the ability to report latitude and longitude while others have the ability to report grid references, altitude, and distance. If you are in need of a GPS device that presents a map, it is important to make sure that the map is displayed at the right scale for ease of accessibility.
When it comes to narrowing down GPS units, you should also keep in mind memory and battery life. GPS devices designed with bigger screens and an array of features use more power, adding more weight to the device and shortening its battery life. To ensure that your device is working optimally when you need it to, check that the GPS unit you acquire meets your needs. Keeping standard, replaceable batteries on hand is optimal , providing you an option to repower your device in the case that it loses power due to extended use.
Maps can also take up a lot of storage space, oftentimes making your device work slower. While some units use external memory, others are equipped with an internal memory and in some cases, have a combination of both. Another important feature to consider is durability. Procuring GPS devices that can withstand environmental stressors such as rain are incredibly beneficial for outdoor applications and uses. In fact, some units can handle getting completely wet and still work optimally. A case can provide added protection, allowing you to safeguard your device in the event that you drop it.
Buttons and touch screen options are available for such devices, allowing users to make a purchasing decision based on preference. While devices with touch screens are easier to use, in cold conditions, shaky hands and thick gloves make them hard to manipulate. Lastly, a myriad of GPS units include a magnetic compass, which allows users to verify the direction they are facing with ease. By moving a short distance, the magnetic compass in the device will inform the user which direction they are moving in.
