Remarks

This sentence provides fix data for GPS, GLONASS, BDS, QZSS, NavIC (IRNSS) and possible future satellite systems, and systems combining these. This sentence could be used with the talker identification of GlobalPositioningSystem for GPS, GlonassReceiver for GLONASS, GalileoPositioningSystem for Galileo, BeiDouNavigationSatelliteSystem for BDS, QuasiZenithSatelliteSystem for QZSS, IndianRegionalNavigationSatelliteSystem for NavIC (IRNSS), and GlobalNavigationSatelliteSystem for GNSS combined systems, as well as future identifiers.

If a GNSS receiver is capable simultanously of producing a position using combined satellite systems, as well as a position using only one of the satellite systems, then separate GNS sentences with different TalkerId may be used to report the data calculated from the individual systems.

If a GNSS receiver is set up to use more than one satellite system, but for some reason one or more of the systems are not available, then it may continue to report the positions using GNGNS, and use the GpsModeIndicator to show which satellit esystems are being used.

Constructors

Name	Description
Gns(string, string[])	Initializes a new instance of the Gns class.

Properties

Name	Description
BDSModeIndicator	Mode indicator for Beidou (BDS)
DgpsStationId	eference station ID1, range 0000-4095 - Null if talker ID is GN, additional GNS messages follow with GP and/or GL Reference station ID
FixTime	Time of day fix was taken
GalileoModeIndicator	Mode indicator for Galileo
GeoidalSeparation	Geoidal separation in meters - the difference between the earth ellipsoid surface and mean-sea-level (geoid) surface defined by the reference datum used in the position solution '-' = mean-sea-level surface below ellipsoid.
GlonassModeIndicator	Mode indicator for GLONASS
GpsModeIndicator	Mode indicator for GPS
Hdop	Horizontal Dilution of Precision (HDOP), calculated using all the satellites (GPS, GLONASS, and any future satellites) used in computing the solution reported in each GNS sentence.
Latitude	Latitude
Longitude	Longitude
ModeIndicators	Mode indicator for future constallations
NavICModeIndicator	Mode indicator for NavIC (IRNSS)
NumberOfSatellites	Number of satellites (SVs) in use
OrthometricHeight	Orthometric height in meters (MSL reference)
QZSSModeIndicator	Mode indicator for QZSS
Status	Navigational status
TimeSinceLastDgpsUpdate	Age of differential data - MaxValue if talker ID is GN, additional GNS messages follow with GP and/or GL Age of differential data
