====== GPS/Compass ======

----

The **GPS/Compass button/indicator** can be placed in one of the **[[:manual:user_guide:functions:panel|Functions panels]]**:\\ {{ :manual:user_guide:tools:gpsscreen01.jpg?nolink |}}\\ It indicates your **internal GPS status**:

  * {{:manual:user_guide:ic_gps_off_default.png?nolink&30}}- acquiring of location is **disabled**
  * {{:manual:user_guide:ic_gps_on_no_fix_default.png?nolink&30}}- searching for location but valid location **not found yet**, location on the map is marked by an //orange circle//
  * {{:manual:user_guide:ic_gps_on_ap_no_fix_default.png?nolink&30}}- the same as above, but //Internal GPS Auto-off//  is **enabled**  (see more in [[:manual:user_guide:settings:gps|GPS settings >>]])
  * {{:manual:user_guide:ic_gps_on_fix_default.png?nolink&30}}- current location is **valid**  (GPS is fixed), location on the map is marked by a //blue circle//
  * {{:manual:user_guide:ic_gps_on_ap_fix_default.png?nolink&30}}- the same as above, but //Internal GPS Auto-off//  is **enabled**  (see more in [[:manual:user_guide:settings:gps|GPS settings >>]])
  * {{:manual:user_guide:ic_gps_simulation.png?nolink&30|}} - GPS simulation is on

The **GPS/Compass button**  switches on a separate two tabbed window displaying [[:manual:user_guide:tools:gps|GPS skyplot and Compass]]. When you **hold**  the GPS/Compass button, a menu appears for a **fast switch of GPS status**.

===== GPS =====
The first tab displays the **skyplot** - placement of monitored GPS satellites and other useful information like current //altitude//, //speed//, //GPS accuracy//, //current coordinates//, //number of fixed/visible satellites// and //time of the last GPS fix//. 

{{ :manual:user_guide:tools:gpsscreen02.jpg?nolink |}}
<WRAP box>
**Legend**
  * //Circles// - satellites of U.S. Global Positioning System
  * //Squares// - satellites of the Russian Glonass positioning system
  * //Triangles// - satellites of Chinese Beidou system
  * //Rhombus// - satellites of the European Galileo system
  * //Color// - signal quality (red - low, yellow - middle, green - high)
  * //Height of bars// - signal to noise ratio
  * //Asterisk above bar// - dual-band satellite, using both L1 and L5 frequencies - much more accurate
</WRAP>
Tapping the skyplot or the button in the bottom **switches GPS on/off**.

==== Source selection ====
 Tapping the side of the bottom button opens a selection of available location sources:\\ {{ :manual:user_guide:tools:gpsscreen04.jpg?nolink |}}
  * **Internal GNSS** - satellite localization unit built in your device combining various providers - GPS, Galileo, Beidou, Glonass...
  * **External GNSS** - a device connected to Locus via Bluetooth or USB

=== GPS simulation ===

  * **Indoor training** - turn on when you need to record your indoor workout
  * **NMEA** - simulation of movement read from NMEA files stored in /Locus/cache/nmea/ directory
  * **Track** - simulation based on a pre-recorded track (beta testing versions only)

Active simulation is indicated red:\\ {{ :manual:user_guide:tools:gpsscreen03.jpg?nolink |}}
==== Topbar menu ====
{{ :manual:user_guide:tools:gpsscreen05.jpg?nolink |}}\\ 
The topbar menu contains shortcuts to several items of your device sensors' settings:
  * **[[manual:user_guide:tools:altitude|Altitude manager]]**
  * **Settings**:
    * **[[manual:user_guide:settings:gps|GPS and sensors]]**
    * **System settings** - direct link to your device operating system settings of location
==== 3D skyplot ====
The skyplot can be switched into a 3D version:

//Settings > GPS&location > 3D skyplot mode - check//

The globe can be enlarged by pinch zooming and rotated.

===== Compass =====

The other tab displays the **compass**, //azimuth, the distance of your navigation target, and tilt of the phone//. Lower line contains also fields for //time to next waypoint// active in navigation and [[https://en.wikipedia.org/wiki/Declination|declination]] value.

The compass ring displays the current position of **the Sun** in the sky.

<wrap tip>Tapping the tilting indicators opens a menu offering sensor calibration.</wrap>
