GNSS Receiver

The GNSS functions allow the program to interact with a GNSS module that supports multiple positioning systems, such as GPS, GLONASS, and GALILEO. The GNSS functionality is not available on all RTCU devices, so please consult the technical documentation for the actual RTCU device in question.

The GNSS functions are to be used together with the GPS functions, where the GNSS functions handle the functionality for multiple positioning systems, while the GPS functions implicitly use all positioning systems.

	•gnssFix	Returns detailed information from the GNSS receiver.
	•gnssSatellitesInView	Accesses information about the satellites in view
	•gnssGetProfile	Returns information about GPS/GNSS features that are available on the RTCU device.
	•gnssEnableType	Enables/disables the individual positioning systems.
	•gnssGetEnabledSystems	Read a bit mask of enabled positioning systems.
	•gnssDynamicModelSet	Configure the dynamic model used by the GNSS module.

Note: all values returned by the GNSS functions are in the WGS-84 datum.

Dead Reckoning

•Dead Reckoning

To improve the performance in areas with poor or no signal conditions, some GNSS modules have support for Dead Reckoning.
