-====== Localisation ======+
  
-The Localisation feature allows you to display ​your real location on the map.+====== Positioning ====== 
 +\\ 
 +The application is able to use the navigation satellite systems (GNSS) chip available in most devices and locate ​your real-time location on the map. Depending of your device capabilities,​ your location can be computed using the GPS, the GLONASS or the Galileo systems, or a mix of them.
  
-Most devices now have a GPS chip which is used to compute this location. GPS provides ​precise location, and doesn'​t need to use any network. However it must have access to the sky. Alternativelyyou can use another location provider if your device doesn'​t have a GPS chip.+The GNSS provides ​an usually ​precise location, and does not require cellular ​network ​coverage. Howeverit must have a clear access to the sky, meaning that it cannot be used indoor.
  
-{{ :en:​help:​1.3:​src_geolocation_submenu.png?nolink|}} +{{:icon_help.png?​nolink}} ​If your device doesn'​t have any GNSS chip, or if this one is disabled in the Android settings, the network location (much less precise) may be used.
  
-===== How to use the Localisation=====+To turn on the real-time positioning and display your location on the map, you can either: 
 +{{ :​en:​help:​positioning:​positioning-submenu.jpg?​nolink}} 
 +  * Long-press the "''​**Positioning**''"​ {{:​icon_01.png?​nolink}} menu button; 
 +  * Tap the "''​**Positioning**''"​ {{:​icon_01.png?​nolink}} menu button, and on the "''​**Real-time position**''"​ {{:​icon_04.png?nolink}} toggle.
  
-You have first to activate the geolocation. You can either: +{{:icon_help.png?​nolink}} ​The GNSS systems may require up to few minutes to retrieve your precise location after being turned ​on.
-  * Long-press the Geolocation menu button ​{{:icon_01.png?nolink|}}+
-  * Open the Geolocation sub-menu, and click on the ''​**Activate**''​ button {{:​icon_02.png?​nolink|}}.+
  
-{{:​en:​help:​1.3:​src_geolocation_information_unfixed.png?​nolink |}} +\\
-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 usedIt means that the current location haven'​t been computed yet.+===== The Positioning menu ===== 
 +\\ 
 +Tap the "''​**Position**''​" {{:​icon_01.png?​nolink}} menu button to display the menu that contains: 
 +  * "''​**Explorer mode**''​" {{:​icon_02.png?​nolink}} activate ​the Explorer mode with perspective view and dashboard;​ 
 +  * "''​**Real-time position**''​" {{:icon_03.png?​nolink}} displays ​the positioning details side-view;
  
-In some cases, ​the application can reuse a previously computed location while the new one is being computedIn this case, the old location is displayed in red like in the previous ​screen-shot.+Tap the "''​**Options**''"​ to display ​the positioning options: 
 +  * "''​**Rotate the map (using GPS)**''"​ {{:icon_05.png?​nolink}} activates or deactivates ​the map rotation to make it match your current direction (you must be moving); 
 +  * "''​**Positioning status**''"​ {{:​icon_06.png?​nolink}} hides or displays of the top/left information box {{:​icon_07.png?​nolink}} containing the most important positioning information. Tap on the settings wheel icon {{:​icon_08.png?​nolink}} to choose what information to display at the screen ​center.
  
-When the application is sent in the background (like when another one is started), the localisation is temporarily deactivated to save battery.+\\
  
-==== Localisation information ​====+===== The menu icon ===== 
 +\\ 
 +The "''​**GPS position**''"​ menu button {{:​icon_01.png?​nolink}} icon and color let you know the current state:
  
-In addition to your location, the Localisation provides useful information such as your current altitude and speed.+{{:​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.
  
-===== Elevations management =====+{{:​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.
 +
 +\\
 +
 +===== Elevations management =====
 +\\
 The elevation of a point is the difference between the altitude of this point and a reference surface of altitude 0 (also called "sea level"​). The elevation of a point is the difference between the altitude of this point and a reference surface of altitude 0 (also called "sea level"​).
