GPS: GPS Receiver

The GPS functions allow the program to interact with a GPS/GNSS module if present on the specific RTCU device. Please consult the technical documentation for the actual RTCU device in use.

For a simple application that demonstrates the GPS functions, please have a look at the GPS Mobile application.

	•gpsPower	Turns on power to the GPS receiver.
	•gpsPowerLP	Turns on power to the GPS receiver in low power mode.
	•gpsFix	Returns detailed information from the GPS receiver.
	•gpsPointInPolygon	Checks whether a point is within a defined polygon.
	•gpsEnableNMEA	Enables NMEA data output on a specific serial port.
	•gpsDistance	Calculates the distance and bearing between two points.
	•gpsDistanceX	Calculates the distance and bearing between two points.
	•gpsGetAntennaStatus	Returns the status of the GPS antenna.
	•gpsNMEA	Returns the NMEA strings.
	•gpsSetSBAS	Enables SBAS-assisted positioning.
	•gpsGetSBAS	Returns the SBAS enable status.
	•gpsPPPStatus	Retrieves the number of satellites using Precise Point Positioning.
	•gpsSetSpeedThreshold	Changes the speed threshold.
	•gpsUpdateFreq	Change the position update frequency.
	•gpsPositionToUtm	Converts a position to Universal Transverse Mercator (UTM) format.
	•gpsUtmToPosition	Converts a position from Universal Transverse Mercator (UTM) format.
	•gpsSemicircleToUtm	Converts a position to Universal Transverse Mercator (UTM) format.
	•gpsUtmToSemicircle	Converts a position from Universal Transverse Mercator (UTM) format.

NX32L devices without built-in GPS modules can use an external GPS device, connected via the USB host port.

This means that the GPS functions can be used with the external GPS module as if it was built-in.

Please note, that should the connection to the GPS device be lost, then the sequence above must be repeated again after calling gpsPower(OFF).
