 +====== GPS & sensors ======
 +----
 +<WRAP center round important>
 +System settings of GPS in your device are superior to all Locus GPS settings - the system GPS being turned off or if Locus does not have permission for accessing GPS (e.g. for battery-saving reasons) especially in stand-by mode may result in incorrect GPS positioning that influences many Locus features. **Check your system settings first!** 
 +</WRAP>
 +
 +===== Global =====
 +
 +==== Run at app start ====
 +
 +Sets the way GPS turns on at Locus Map startup:
 +
 +  * **Always**  - GPS turns on always when Locus Map is started
 +  * **Previous state**  - GPS turns on or stays off according to last Locus Map session
 +  * **Never**  - GPS never turns on at Locus Map start
 +==== Altitude manager ====
 +
 +Sets **[[:manual:user_guide:tools:altitude|options to improve altitude measurement >>]]**
 +===== Orientation =====
 +==== Compass ====
 +Allows to choose either built-in hardware compass or GPS-calculated azimuth for orientation that is essential for map rotation and the compass screen.
 +  * **Hardware compass** - more suitable for slower speeds, e.g. walking, as it does not require movement to detect direction unlike GPS.\\ <WRAP round important> Mobile hardware compass is very sensitive on nearby magnetic metals and may display malformed values in their close presence, e.g. magnetic flip-cases or steel steering bars. </WRAP>
 +  * **Orientation via GPS** - more suitable for car navigation due to magnetic components in the car that can affect performance of the hardware compass.
 +  * **Auto-change** - shifts bearing automatically between hardware compass and GPS according to pre-defined critical speed. 
 +
 +==== Use true bearing ====
 +
 +Sets navigation by true bearing instead of magnetic bearing. 
 +==== Compatibility mode ====
 +Orientation is computed by an alternative method. Suitable for some devices.
 +===== Notification settings =====
 +
 +==== Position acquired ====
 +
 +Notifies when your device acquires GPS location. Opens notification settings screen with several options to define the sound and vibration alert (beep, any sound from your phone library…).
 +
 +==== Position lost ====
 +
 +Notifies when your device loses GPS location. Opens notification settings screen with several options to define the sound and vibration alert (beep, any sound from your phone library…). 
 +
 +===== Disable location =====
 +
 +==== Disable when app is hidden ====
 +
 +Disables GPS when the screen is turned off or the app is minimized and GPS location is not required by any other function
 +
 +==== GPS ON for track recording ====
 +
 +Keeps GPS on during the track recording even if the recording is paused.
 +
 +==== GPS ON for guidance ====
 +
 +Keeps GPS on during guidance even if the app is minimized and screen is off.
 +
 +===== Bluetooth GPS =====
 +
 +Launches the [[:manual:user_guide:tools:bluetooth|Bluetooth manager]] to enable GPS from a bluetooth device instead of the internal GPS. The advantage is better GPS accuracy and lower phone battery consumption.
 +
 +===== Advanced settings =====
 +
 +==== GPS auto-off ====
 +
 +Allows automatic turning on/off of your device GPS unit in order to save the battery life. Pre-defined conditions:
 +
 +  * **GPS update interval**  - sets time interval of GPS switching on and locating the device. Values of more than 60 seconds save battery life.
 +  * **Min accuracy**  - sets minimum GPS locating accuracy to keep GPS on. When the accuracy is lower due to few detectable satellites, the GPS turns off.
 +  * **Max search time**  - sets maximum time of GPS signal searching. If the GPS fix is not secured within this period, GPS turns off.
 +  * **Keep auto-off enabled** - keeps GPS auto-off enabled even if Locus Map is active and screen is on.
 +<WRAP center round alert>
 +This option is **not available on devices running OS Android 12+** due to its newest restrictions of certain automatic actions running in the background.
 +</WRAP>
 +==== 3D skyplot mode ====
 +
 +Switches between 2D and 3D display of the skyplot that is available under the [[:manual:user_guide:maps_mainscr_ctrl#gps_compass_icon_button|GPS/compass button]] on the main screen:\\ {{ :manual:user_guide:settings:settings_51.gif?nolink |}}
 +==== Google Services assisted location ====
 +More stable and battery efficient location method on some devices. Using [[https://developers.google.com/location-context/fused-location-provider/|Fused Location Provider]] for getting location of the device. Fully functional provided Google Services have GET_LOCATION permission.
 +==== NMEA recording ====
 +
 +Enables recording GPS NMEA to data/nmea directory when GPS is on or in time of active track recording. [[http://www.gpsinformation.org/dale/nmea.htm|More about NMEA >>]]
 +
 +==== Reset A-GPS data ====
 +
 +Forces GPS to reload online Assistant GPS data to improve its startup performance. [[http://en.wikipedia.org/wiki/Assisted_GPS|More about A-GPS >>]]
 +==== GPS accuracy circle ====
 +Displays a circle around your actual position describing accuracy of received GPS data:\\ {{ :manual:user_guide:settings:settings_52.png?nolink |}}
