IF ErrorOccurred = False THEN
Info(" Latitude: " + pos..Latitude)
Info(" Longitude: " + pos..Longitude)
END

Syntax

<Result> = GPSLastPosition()

<Result>: geoPosition variable

Name of geoPosition variable. This variable contains the information about the last known device position. To find out whether the position failed to be retrieved, use the ErrorOccurred variable.

Remarks

Special cases

To find out whether the ..Speed, ..Precision, ..Direction or ..Altitude properties of a geoPosition variable have been filled when retrieving the position, use ..SpeedValid, ..PrecisionValid, ..DirectionValid and ..AltitudeValid.
To reinitialize a geoPosition variable, use VariableReset.
We advise you to initialize the parameters of localization provider with GPSInitParameter before retrieving a position.
The positioning information that was retrieved corresponds to the last known device position: therefore, they may not correspond to the current device position if the device was moved while the GPS signal was not valid for example.
To find out the date and time at which the position was calculated, use the MeasurementDate property of geoPosition variable.
..Speed, ..Precision, ..Direction and ..Altitude will be filled only if the localization provider allows it (otherwise, these properties will take their default value). The localization provider can be configured by GPSInitParameter.
