GPS Navigation: Determines the Location

GPS Navigation, or Global Positioning System navigation, determines the location of the GPS device on or just above the planet Earth. There are many devices these days that feature GPS navigation, ranging from cars, cell phones, portable computers and compasses. Where ancient mariners had to use the stars to navigate, we can use devices among the stars to tell us where we are.

A GPS navigation device contains a small radio receiver micro-chip that uses information received from multiple GPS satellites to determine the exact location of the receiver, virtually anywhere on the planet. It uses more the just one satellite as the location is determined based on the information received from satellites in different positions and orbits above them. This type of positioning   is called triangulation and it is very effective.

Not all GPS devices make use of a navigational map system. Some, such as certain cell phones or compasses, are simply devices to let you know your longitude and latitude for informational purposes. The map technology has to be added into the device from the manufacturer and even this still has some limitations. These systems can only determine your route based on the map data they incorporate. If a road is changed or even eliminated, or if you leave a mapped road, to an unmapped off-road, the device will know where you are, and can give you coordinates, but it won’t be able to offer directions and it will most likely repeatedly tell you to get back on the known road.

GPS navigation, while impressive, is not the be all and end all of how to get from point A to point B. simply put, electronic devices can break down or run out of power so it’s a good idea to have a paper map available or have a simple GPS navigation back-up system like a cell phone. With a cell phone’s GPS navigation system, you may not be able to get directions but you can find out exactly where you are on a regular map, which you can use to find your way back to a mapped area again. You can also use that location to access emergency help, if needed.

There are Pocket PCs with GPS navigation systems incorporated into their design. These Pocket PCs are some of the most intelligent uses of a GPS navigation system for many people. Along with software for the GPS navigation systems, you are able to see where you are and also what is around you through satellite photography. This combined technology can be extremely helpful if you become lost or your car breaks down in a remote area. Regardless of how you intend to use GPS navigation, know what your needs are and what you intend to use it for and ask plenty of questions, so you get the GPS navigation system you want.

Consider the layout of your car. Some systems come with a monitor that displays a map. The monitor is commonly installed on the dashboard or on a pedestal extending from the dashboard. In some cars, such an installation may block air vents or make it somewhat uncomfortable for a passenger to enter or exit the vehicle or sit in the passenger seat.

Select a system that features multiple ways of getting to your destination. This can include by address, by intersection, by a personal address book or via a location selected directly from the map.

Look for a system that gives you vocal as well as graphical directions. The systems that use a map and monitor include arrows that show you the direction of a turn and also indicate where your car is on the map in relation to the destination. Other systems use the head unit or radio to display the name of the street on which you are to make a turn or on which you are traveling. Both of these systems also give you verbal directions as you approach a turn.

Select a system that includes point of interest data. Most GPS systems include locations of airports and other transportation services, ATMs and banks, restaurants, hotels and a host of other sites.

Choose a system that offers updates of the point-of-interest data.

Consider installation time if you are working on a tight budget. Systems that rely on maps displayed on monitors are more complicated and take longer to install than other types of systems.

Once all specifications have been identified for your GPS system, price different units out. Most retailers will have demo units in-store that you can see, touch, and experience. You can always check online retailers from China manufacturer for a better price. Don’t forget Topons.

A few nice GPS Navigation images I found:

screenshot example for geo-tagging (google-earth) / photo logger


Image by Right-eye
Geo-logger or geo-tagger (small gadgets of about 40 gr) allow to record the way you cover, they store time and geodata so that a photo, which has a timeprint (as normally all digital photos have), can be assigned to a certain place (of course camera and geo-tagger should have been at the same place when the photo is taken
Here the gadget was set to record the position every 10 meters.
In the near future the cameras will have an integrated gps (global positioning system) so that photo logging will be a matter of course.

An amazing piece of software is finally launched in Australia!
Slightly annoying that it kills your music player or FM radio when the voice announces a turn. Would be nice if the music resumed.
