GPS Settings

These settings are found in the GPS section of the Configuration menu.

Operation

Enable GPS As Needed - To obtain the highest accuracy, GPS services are always in use by default. Enable this option to only turn on GPS when needed, which will help preserve battery life.

Note: GPS services can take time to obtain accuracy when first enabled, so if this setting is enabled, then we recommend waiting to obtain accuracy before digitizing new features. For more information see Enabling Location Services

Best Accuracy - This is enabled by default. The device will return the most accurate location data the hardware is capable of. This will be on the order of 10 m with an internal GPS unit.

When disabled, the device will not work the hardware as hard, prolonging battery life. (This may disable GPS and use only Wi-Fi location services.) However the accuracy will be on the order of 100 m.

We recommend enabling best accuracy when using GPS related functions, such as displaying the current location and creating features using location data. Disable Best Accuracy if you are not using higher accuracy GPS related functions and battery life is an issue.

Pole Height (Advanced GPS) - + This feature requires a Pro license - Enter a pole height to be used as a vertical offset when using an Advanced GPS source. Features recorded using a GPS create option will have the elevation offset by the pole height and gain the attribute ADVGPS_POLE_HEIGHT.

Keep Application Awake - When enabled the device will not go to sleep while the Global Mapper Mobile application is open and displayed on the device. This uses more battery power.

Display

Always Show GPS Info - When enabled coordinates and accuracy of the GPS location will be shown regardless of display settings.

Show Accuracy - When enabled, a light blue circle will be drawn around the GPS position display symbol, indicating the accuracy range. Some GPS units do not report accuracy. In these cases, the accuracy will read as “Not Reported“.

Show Distance and Bearing - + This feature requires a Pro license - When enabled the distance and bearing from the GPS location to the selected point feature will be shown below the GPS Info.

Differential Age Threshold - Set a differential age threshold between 1 and 300 seconds. Age will be red in Coordinate Info Display if the last correction received is older than the set threshold.

Horizontal Accuracy Threshold - Set a horizontal accuracy threshold in meters between 0.01 and 100. Accuracy will be red in Coordinate Info Display if above it is above the set threshold.

Digitizer

Added Vertex Sound - Specify the sound to use when adding points. Note the sound will not play if the device is set to silent.

Default Point/Line/Area Types - Use these options to set the default feature type and style for features created using a GPS mode.

Record Distance Interval - The distance interval is used with the GPS Auto Distance option for creating Points, Lines or Areas.

Record Time Interval - The time interval is used with the GPS Auto Time option for creating Points, Lines or Areas. The time interval is set in seconds.

Simultaneous GPS Tap Points - Enable to create GPS Tap Points while a GPS Auto (Time or Distance) digitizing mode is being used.

Average GPS

GPS Average Min Horz Accuracy - Specify the minimum horizontal accuracy of point to be included in GPS average calculation.

GPS Average Show Data Points - When enabled all points used to calculate average will be displayed.
