GPS systems can be used in many ways. There are some hobby uses such as geocaching, which includes a list of locations where the user can find treasures that are usually trinkets and other low-value items. More hobby-oriented uses include camping and hiking. It is a difficult task to determine exactly where the hiker is on the map. The smaller the terrain, the harder it is to find a more accurate location. In the desert it is very difficult to accurately determine where you are, without having to spend time on calculating resection on the map. This can also occur in environments with low visibility, such as marsh or forest. Only real alternatives are dead count or GPS.
GPS systems allow the hikers or caravans to freedom. With a compass, the hiker or the caravan must always remember the navigation. A pre-planned course can only be tracked when the user navigates from point to point, tracking the distance traveled and the direction of the entire time. If the terrain allows, a certain amount of freedom can be made from the identifiable location to navigate to the identifiable location. With GPS, hikers will only have to worry about general places, and if we go in the right direction and if there are no rocks or other things to avoid them, we simply pay more attention to the final venue. In essence, the GPS receiver allows freedom of orientation even for those who usually navigate with a compass.
Other uses of GPS systems include fishing and hunting. Places can be provided for others to find good places. This is especially valuable if you keep fishing from convenient places to visit. It may be difficult to find a sub-function like a sandbox that provides a convenient space for feeding fish, but GPS systems allow users to easily locate fishermen's locations.
GPS systems are a surprising use of parachuting. This increases the ability of the pilot to reach the right place to assist paratroopers in an attempt to get to the drop zone.
Another goal is to use airline passengers. Some passengers like to use the GPS to track their location to show themselves that they are moving towards the destination. Although all airlines prohibit the use of GPS devices during take-off and landing, some also prohibit their use for full flight. On the other hand, some also provide a GPS system for passengers typically built into the rear of the front seat. GPS systems also provide very accurate time, as systems continuously allow self-correction based on satellite constellation.
If time is off, the system will not be able to synchronize the signals, so GPS systems are built to use the signals from the satellites to hold their time very tight. For those who need very accurate timing, it's cheaper than the most expensive watches and more accurate.
