Having Safe Adventures With Outdoor GPS

Have you ever found yourself wondering out loud where you are? You may have made a generalized guess but did not arrive at an answer that truly determines the question. Yet, with new technology this is a question that is fairly easy to answer. The release of the Global Positioning System (GPS) has made the ability to locate your position simple and easy.

Some may believe that the original concept of GPS navigation originated over a hundred years ago when the explorers looked to the stars to define their position. Actually, the true origin of modern GPS technology begins in the 1950’s. Such systems were originally created for military use. A unification of MIT, the DoD, and Ivan Getting helped craft these amazing technological improvements. Now, the process uses eight satellites and is dubbed the Navigation System with Timing and Ranging (NAVSTAR).

Nowadays, the GPS realm is comprised of 24 orbiting satellites the spin around the earth twice a day and transmit information regarding location and time. A Garmin GPSMap 78sc Handheld GPS Navigator or, really, all handheld GPS receivers can do what is needed to determine your precise location all over the earth whether you are hiking in the Adirondack or sailing across the Indian Ocean. A GPS receiver will work through figuring out the distance between the satellite and the user relying on signals that are picked up between a minimum of three satellites. However, if elevation info is required, the system will need to tap into at least four satellites.

People that love the great outdoors and wish to go venturing on adventures will find a handheld GPS receiver a must have. This device would help those that are pilots, boaters, hikers and others find their exact location through a simple and basic push of a button and entering their general location into the memory. A GPS will guide such people to where they wish to go and return back to where they were. A high quality GPS unit along the lines of the Garmin GPSMap 78sc Handheld GPS Navigator and new releases of GPS models that have the potential to present clear data presenting latitude and longitude, Military Grid Reference System (MGRS) and UTM (a grid employed by the Bureau of Land Management).Units such as this must maintain a tracking log that will allow users to effectively retrace steps without much difficulty. The GPS receivers must also be highly sensitive to cover an enhanced satellite reception despite potentially being in a deep canyon or an area that is covered in dense trees.

With outdoor GPS units, the battery life of the system must last upwards of 12 hours and this will also include the dual use of compass and GPS. The unit must also have the potential to upload and download data to a computer or with a mapping system that is totally computerized while also displaying the information as accurate as needed. The memory of the system should be enough to store up to 500 waypoints.

Since the GPS unit will be exposed to different weather conditions and prone to rough handling, the casing should be rubberized and durable. The backlights should be high enough that the data can be read even at night or in any situation with low lights. Garmin GPSMap 78sc Handheld GPS Navigator and other more modern GPS receivers have built-in electronic compass that can help determine where the user is and know the direction he’s heading even when standing still.The more high-priced the GPS unit is, the more features it has. This advancement of outdoor technological navigation is making outdoor adventures fun, exciting and safe.
