-===== How to use the Localisation=====+{{:icon_help.png?nolink}} If your device doesn't have a GPS chip, or if this one is turned off in the Android settings, the network location (much less precise) may be used.
  
-You have first to activate the geolocation. You can either: +To turn on the GPS positioning and display your real location on the map, you can either: 
-  * Long-press the Geolocation menu button {{:icon_01.png?nolink|}}; +  * Long-press the "''**GPS position**''" menu button {{:icon_01.png?nolink}}; 
-  * Open the Geolocation sub-menuand click on the ''**Activate**'' button {{:icon_02.png?nolink|}}.+  * Open the sub-menu and click on the "''**Positioning details**''" toggle button {{:icon_03.png?nolink}}.
  
-{{:en:help:src_geolocation_information_unfixed.png?nolink |}} +{{:icon_help.png?nolink}} The GPS may require up to few minutes to retrieve your precise location after being turned on.
-The GPS will then try to compute your location based on the information retrieved from GPS satellites.+
  
-The localisation information box let you know how much satellites have been found yet. In this case, ''**0/5sats**'' means that ''**5**'' satellites have been found in the sky, but ''**0**'' are being currently used. It means that the current location haven't been computed yet. 
  
-In some cases, the application can reuse a previously computed location while the new one is being computed. In this case, the old location is displayed in red like in the previous screen-shot.+===== The sub-menu =====
  
-When the application is sent in the background (like when another one is started)the localisation is temporarily deactivated to save battery.+Click on the "''**GPS position**''" menu button {{:icon_01.png?nolink}} to display the sub-menu, containing the following items: 
 +  * The "''**Positioning details**''" button {{:icon_02.png?nolink}} opens the positioning details panel; 
 +  * The "''**Positioning details**''" toggle {{:icon_03.png?nolink}} activates or deactivates the positioning; 
 +  * The "''**Rotate the map (using GPS)**''" check-box {{:icon_04.png?nolink}} activates or deactivates the map rotation to make it match your current GPS orientation (you must be moving); 
 +  * The "''**Display distance line**''" check-box {{:icon_05.png?nolink}} activates or deactivates the drawing of a line from the map center to your current location including its distance (see {{:icon_07.png?nolink}} below); 
 +  * The "''**Positioning status**''" check-box {{:icon_06.png?nolink}} activates or deactivates the display of a box on the map giving the most important positioning information (see {{:icon_08.png?nolink}} below).
  
-==== Localisation information ==== 
  
-In addition to your location, the Localisation provides useful information such as your current altitude and speed.+===== The menu icon ===== 
 + 
 +The "''**GPS position**''" menu button {{:icon_01.png?nolink}} icon and color let you know the current state: 
 + 
 +{{:en:help:geolocation:menu-off.jpg?nolink}}  When the icon is white, the GPS positioning is turned off. Long-press the button to turn it on. 
 + 
 +{{:en:help:geolocation:menu-on-locked.jpg?nolink}}  When the icon is green, the GPS positioning is turned on and the current location is displayed at the map center (or being retrieved). Long-press the button to turn it off. 
 + 
 +{{:en:help:geolocation:menu-on-unlocked.jpg?nolink}}  When the icon is green with a lock key, the GPS positioning is turned on and the current location is currently not displayed at the map center (you're looking somewhere else on the map). Click on the button to center the map on the current location. 
 + 
 + 
 +===== The on-map positioning ===== 
 + 
 +{{ :en:help:geolocation:on-map-positioning.jpg?nolink}} 
 + 
 +When turned on, the GPS will try to compute your location based on the information retrieved from GPS satellites. 
 + 
 +If the "''**Positioning status**''" option is checked, an information box {{:icon_08.png?nolink}} lets you know how much satellites have been found yet. In this case, ''**4/8sats**'' means that ''**8**'' satellites have been found in the sky, and ''**4**'' are being used to compute the current location. If ''**0**'' satellites are being used, then the current location has not been found yet. 
 + 
 +If your current location has been found, this one is displayed in blue on the map {{:icon_09.png?nolink}}. A circle indicates the area of precision (your real location is somewhere inside the circle, usually but not necessarily at the center). An arrow indicate your direction (while moving), and the information box {{:icon_08.png?nolink}} gives you the following information: 
 +  * The current location accuracy, its elevation, speed, and fix number; 
 +  * The distance and bearing to the map center (if different). 
 + 
 +{{:icon_help.png?nolink}} In some cases, while retrieving the current location, the application can display an older one. In this case, this old location is displayed in red. 
 + 
 +{{:icon_help.png?nolink}} When the application is sent in the background (or when another one is started over), the positioning is temporarily deactivated to save the battery. This default behavior can be deactivated in the application settings.
