What is GPS? To Serve a GPS? … Practical Guide to GPS

Author: BODECOR (6020)

Circulating in the area has about 20 satellites that are capable of giving us the position on the earth taking into account the rate of emission of waves between them and a GPS. The mathematical foundations are complicated and need not concern us too, it really is to know what can be done with a GPS, in what sense are useful to us.

There GPSs for cars and GPSs for hiking, sailing, etc.. Some Member States have included an accurate map of roads, such as cars, drive you to them once you have set a destination and there is no map, as the most elementary of hiking, which lead us to a point which we are adding (coordinates) or lead us on a tour true that we have introduced previously.

What concerns us here are hiking or GPS navigation, etc.. which are the same. They are small gadgets (like the palms and less) laptops, designed to bring the mountain. They run on batteries that come to last between 4 and 10 hours, though they say it last longer. There are two outstanding brands in the market for this type of GPSs, GARMIN and MAGELLAN.

BASIC NAVIGATION

Initializes the GPS. After the previous settings, we must place ourselves in an open pit area for the terminal is switched on, determine its new position and know which satellites are at that moment is in? View?. Currently I tend to do automatically, but you get the approximate coordinates we introduce our position. The first time it will take a few minutes to initialize, but at the following times, but it takes a long while since we use it, or turn on after a long journey, will be operational within seconds.

1st practice. Let us start with theory and a practical exercise very basic, but that fully reflects the philosophy of GPS navigation and ultimately, the practice is the best way to understand and learn the use of any tool.

For this first experience we can do so from the door of our own home, start with initialize the positioner, once you tell us that they are operational, we will mark this location and save it as a waypoint, which we can call home, for example. Then start walking (we look at the speed in km / ha which we walk), when we make a significant change of direction (+45 ?), we will take the waypoint? What we call 001, and so on, it is not necessary much longer the walk, with enough will get 5 points.

The time has come to ours? Marvel of art? guide us to our house, we will initially with the most basic function: located in the last waypoint? WP004, using the keypad on the earlier we will? WP003-and ask a GOTO, and we screen pointer will indicate the direction and course that we should take, no doubt arrive at WP003 (you can see the distance to the WP003, as you walk toward him), if increases are not going the right direction.

IMPORTANT: GPS MUST BE MOVING TO WORK, IF OS PARADISE BE FLAWED DATA.

As you have done previously, you can do to turn the WP002 and WP003 this the first we call HOUSE.

Taking advantage of that and we have 5 waypoints stored, we will exercise a bit more advanced:

With the instructions provided us with the GPS, we’ll create a route, ie WP will tell you that we want to go HOME WP001, WP002 this the WP004 and so on.

Once you create a route, we just have to say that navigation starts, we’ll be leading by one point to another without having to Gouty, to reach a point jumps automatically to the next until the end of the route.

The last practice that we propose to familiaric?is with this system you can make to the continuation of the previous, from WP004, look in the TRACK menu function. This screen will indicate the percentage of memory that we have occupied, with previous years we have certainly not exhausted, so it will ask for a BACK TRACK automatically and also with the screen pointer, faithfully guided us to the starting point — CASA-WP

For the function TRACK we have to be outstanding memory capacity we have, to not lose track of the principle points of the route, you should delete the stored before starting a new route, thus ensuring 100% of the memory.
