Using GPS Tracking Device will enhance your basic navigational skills

Декабрь 29th, 2015 by homesecuirtycameras and tagged , , ,

Most GPS receiver cases have a loop on the back to hold the case on a belt. If you’re wearing shorts or tights and don’t have a belt, waist packs for carrying a radio or a cassette/CD player are an option. These packs can accommodate larger GPS receivers. They’re not very noticeable when you’re working out because they’re designed not to bounce much. Small fanny packs and waist packs that carry water bottles also carry a GPS receiver. If the GPS receiver is small, try carrying it in your front pants pocket. I’ve carried a GPS while running and cross-country skiing in trail-running shorts and tights with zipper pockets. Although satellite reception is sometimes lost while under heavy tree cover, the GPS receiver records track data as long as I have a mostly clear view of the sky.

Using GPS will greatly enhance your understanding of the map-and-compass technique, but it’s wise to hone basic navigational skills before or in conjunction with use of a GPS tracking device. When out in the field, you will develop your own style of GPS use. You may want to plot a course ahead of time, upload it to your GPS, and follow that. You may want to upload only key points of your journey such as crucial trail intersections, waterfalls, high points, or shelter locations. You may want to carry the GPS along without uploaded data and navigate without the aid of pre-plotted track points or waypoints. Or you may just want to have the GPS to turn on once or twice a day to check your position against a map.

The Timex Speed + Distance system is a cigarette pack-size GPS magnetic tracker that straps on your arm and transmits data to a special wristwatch. You can look at your watch and see how far you’ve gone and how fast you’re going. Timex updated the system in 2003, adding more components and calling it Bodylink. In addition to the GPS receiver and watch, the Bodylink includes a heart-rate monitor (the GPS receiver, watch, and heart-rate monitor ) and a data recorder that collects data from both the GPS receiver and the heart-rate monitor. You can connect the data recorder to your personal computer to upload your workout data and analyze it with the included software.

Even with vehicle GPS tracking device technology becoming better every day, it is still a good idea to have backup navigation. Having a paper map, a simple compass,and knowledge of manual navigation is a good, safe practice of prudent navigators! Remember, GPS is a complement to navigation and should not be the only navigational tool you use.

The main disadvantage to carrying your GPS receiver on or below your waist is that it’s not the best place for satellite reception. There’s a good chance that you’ll lose the signal in areas with reduced satellite coverage. If you use a hydration pack or a lightweight backpack, you can get your GPS higher for better satellite reception by mounting the case either on one of the front shoulder straps or putting the GPS receiver in the upper, top pocket of your backpack. (It isn’t as accessible in the backpack pocket but should get good satellite reception.

Essential applications for electronic tracker

Декабрь 22nd, 2015 by homesecuirtycameras and tagged , ,

motorcycle GPS tracker are designed with many built-in features but only a few are essential for wilderness navigation. Any feature that requires the tracker to stay switched on for prolonged periods should be used sparingly as conserving battery power is an important consideration, especially in cold weather.

Not all GPS receivers can display maps. Lower-cost models (typically under $150) or GPS receivers with very small screens usually don’t support maps. If you already own a GPS receiver, make sure that it’s compatible with the map software you’re interested in using. Manufacturer Web sites are pretty good about listing product compatibility. The same holds true if you’re shopping for a new GPS receiver.

You can use only proprietary products (made by the same company that manufactures your GPS tracker). Admittedly, I’m belaboring this point, but a fair number of novice GPS users think that they can load just about any map on their new GPS tracker, which isn’t the case.

Don’t expect the level of detail in a GPS map to match paper maps. In order to maximize memory space, Magnetic GPS use vector maps (created with lines and shapes) instead of raster maps (scanned paper maps). And because a GPS tracker has a fairly small screen to display a map, don’t expect the map on your GPS tracker to appear as an identical version of your favorite paper map. Until tracking devices for people incorporate science-fictionlike, holographic projection systems where a map appears in midair (and I’m not holding my breath), viewing a paper map will always be easier and more effective than staring at a map on a GPS tracker.

Determining your position

The ability to pinpoint your position during any type of weather almost anywhere on Earth is the most basic application of a waterproof tracking devices. Just switch on the tracker and wait for a position fix. Your position can be displayed as a grid number, a geographic coordinate, or a point on a built-in digital map. With signals from a minimum of four satellites, the tracker will display your elevation.

Storing a position as a waypoint

A waypoint is simply a named set of coordinates representing a position. Once your tracker has acquired a position fix, you can store the position in the tracker’s memory as a waypoint. This is very useful for finding your way back to the position. You could also give the waypoint’s coordinates to someone else, who could then find the waypoint with his or her own tracker.

Inserting a waypoint

You can manually key a position into your tracker’s memory as a waypoint without ever having set foot at that location. The coordinates for the waypoint could be obtained from a printed map or from someone else who has previously been there. With a computer, you can insert waypoints electronically into a GPS tracker from a digital map.

Navigating toward a waypoint

Finding your way toward a stored waypoint is the essence of GPS navigation. With waypoints stored in its memory, switch on the tracker and let it acquire a position fix. With a few keystrokes, the tracker will display the distance and bearing toward any stored waypoint. There are two primary ways to navigate toward a stored waypoint: (1) using the tracker by itself, or (2) using it together with a compass. By itself, the tracker must be switched on continuously. With a compass, the tracker requires only intermittent use with most of the navigating done by the compass.
