In portable GPS navigators, the basic information is presented to the user in the form of on-screen pages with the help of which navigation is carried out. Knowing the main screen pages, you can quickly make a general opinion about the main features of the navigator. The main screen pages are divided into navigation, information and control.
Navigation methods in portable GPS navigators, free navigation, navigation on the return and saved path, to a given point, along the route.
As the name implies, the navigation pages are intended for current navigation, and in them we will highlight such pages as a Map (Map Page), Index (Compass Page, Pointer) and Highway (Highway Page). The information pages include Satellite (Satellite Page), Trip Computer (Trip Computer Page) and Elevation Page (Elevation Page). The last group of control pages contains the Menu (Main Menu) and Settings (Setup, Setup). The purpose of the latter is obvious.
Of course, from each page you can call up the optional page and tabs, which also apply to managers. But this is not about them now, because they are pages of a lower (second) level, for example, the Route and Track pages. If the Map page provides the user with an overview of the terrain with a path line drawn on it, then the Index and Highway pages directly direct navigation to a given point when it is defined. Let us single out several main navigation methods, depending on the definition and assignment of the travel destination (goal).
Free GPS Navigation.
The destination point is not defined and not defined, that is, we go where our eyes look. In this mode, the Map page is used. The navigator draws a route along which, if necessary, waypoints can be marked. The track (path) is stored in the memory of the navigator.
GPS navigation on the way back (Return, TgasVask).
This navigation method allows you to move exactly along the path traveled in the opposite direction. In it, the destination is the starting point of the path or start. Since the destination point is set, you can use both the Index page and the Trunk page for navigation. Previously, you must save the distance traveled in the GPS memory of the navigator. The current (return) route and the previously saved path are displayed on the map screen. Therefore, it is easy to notice the deviation of the current line of the path from the saved path and thereby adjust its further path.
GPS navigation on a saved path, track.
The method is close to Tgasvask. Once traveled and saved path (Track) can be used repeatedly. At the same time, in the saved path, the start (BEGIN) and end (END) points are automatically marked, which allows you to select one of them and always correctly determine the desired direction of movement. The name of the selected point is displayed on the Index and Highway pages as the name of the destination (target).
Translations of GPS navigator instructions use different terms for the same. So, the mode and the Index page (Pointer Page, Navigation Page) are also called the Compass Page. The best, from our point of view, would be the use of the term “course guidance”. But in order not to create confusion, we are forced to adhere to the terms introduced by distributors.
GPS navigation to a given point (Direct route, GOTO).
First you need to select a destination from the list of waypoints or other points stored in the GPS memory of the navigator. Then select the GOTO mode (Go on, Direct route). It’s convenient to use the Index and Trunk pages to navigate this method. A certain limitation of the method – however, not too burdensome – is the navigator indicating the path to the selected point in the form of a straight line. Naturally, as in other methods, all forced deviations from the proposed rectilinear direction are displayed, and the user can see how to adjust the direction of movement.
GPS navigation along the route (Route, Route).
To navigate a route, you must, of course, create it. A route is a sequence of waypoints, they can also be waypoints, in which the movement between two neighboring ones is carried out in a straight line. The movement along the route is more convenient than the GOTO mode, since it ensures the passage of all the planned points without their manual selection. The GPS navigator according to the route will automatically select the next point in order, indicating the calculated azimuth and the distance from the current location.
