Member Enumeration Documentation

◆ Attribute

enum QGeoSatelliteInfo::Attribute

Defines the attributes for the satellite information.

\value Elevation The elevation of the satellite, in degrees. \value Azimuth The azimuth to true north, in degrees.

Azimuth

Definition at line 36 of file qgeosatelliteinfo.h.

◆ SatelliteSystem

enum QGeoSatelliteInfo::SatelliteSystem

Defines the GNSS system of the satellite.

\value Undefined Not defined. \value GPS Global Positioning System (USA). \value GLONASS Global Positioning System (Russia). \value GALILEO Global navigation satellite system (EU). \value BEIDOU BeiDou navigation satellite system (China). \value QZSS Quasi-Zenith Satellite System (Japan). \value Multiple This type normally indicates that the information is received from a device that supports multiple satellite systems, and the satellite system is not explicitly specified. Depending on the data source, you might use other information to determine the actual system type. One example of the usage of this type is an NMEA $GNGSA message, which contains the IDs of the satellites being used, but does not explicitly mention their system types. \value CustomType The first type that can be used for user purposes. For example when reimplementing NMEA data parsing in \l QNmeaSatelliteInfoSource. User can add more types using {CustomType + 1}, {CustomType + 2} and so on.

Constructor & Destructor Documentation

◆ QGeoSatelliteInfo() [1/4]

QGeoSatelliteInfo::QGeoSatelliteInfo ( )

Creates a satellite information object.

Definition at line 58 of file qgeosatelliteinfo.cpp.

◆ QGeoSatelliteInfo() [2/4]

QGeoSatelliteInfo::QGeoSatelliteInfo ( const QGeoSatelliteInfo & other )

Creates a satellite information object with the values of other.

Definition at line 70 of file qgeosatelliteinfo.cpp.

◆ QGeoSatelliteInfo() [3/4]

QGeoSatelliteInfo::QGeoSatelliteInfo ( QGeoSatelliteInfoPrivate & dd )

Definition at line 75 of file qgeosatelliteinfo.cpp.

◆ QGeoSatelliteInfo() [4/4]

QGeoSatelliteInfo::QGeoSatelliteInfo ( QGeoSatelliteInfo && other )

defaultnoexcept

Since: 6.2

Creates a satellite information object by moving from other.

Note that a moved-from QGeoSatelliteInfo can only be destroyed or assigned to. The effect of calling other functions than the destructor or one of the assignment operators is undefined.

◆ ~QGeoSatelliteInfo()

QGeoSatelliteInfo::~QGeoSatelliteInfo ( )

Destroys a satellite information object.

Definition at line 93 of file qgeosatelliteinfo.cpp.

Member Function Documentation

◆ attribute()

qreal QGeoSatelliteInfo::attribute ( Attribute attribute ) const

Returns the value of the specified attribute as a qreal value.

Returns -1 if the value has not been set.

See also: hasAttribute(), setAttribute()

Definition at line 248 of file qgeosatelliteinfo.cpp.

◆ detach()

void QGeoSatelliteInfo::detach ( )

Definition at line 275 of file qgeosatelliteinfo.cpp.

◆ hasAttribute()

bool QGeoSatelliteInfo::hasAttribute ( Attribute attribute ) const

Returns true if the specified attribute is present in this update.

Definition at line 267 of file qgeosatelliteinfo.cpp.

◆ operator=()

QGeoSatelliteInfo & QGeoSatelliteInfo::operator= ( const QGeoSatelliteInfo & other )

Assigns the values from other to this object.

Since: 6.2

Move-assigns the value from other to this object

Note that a moved-from QGeoSatelliteInfo can only be destroyed or assigned to. The effect of calling other functions than the destructor or one of the assignment operators is undefined.

Definition at line 102 of file qgeosatelliteinfo.cpp.

◆ removeAttribute()

void QGeoSatelliteInfo::removeAttribute ( Attribute attribute )

Removes the specified attribute and its value.

Definition at line 258 of file qgeosatelliteinfo.cpp.

◆ satelliteIdentifier()

int QGeoSatelliteInfo::satelliteIdentifier ( ) const

Returns the satellite identifier number.

The satellite identifier number can be used to identify a satellite within the satellite system.

The actual value may vary, depending on the platform and the selected backend.

For example, if nmea plugin is used, the satellite identifier for GPS satellite system represents the PRN (Pseudo-random noise) number, and the satellite identifier for GLONASS satellite system represents the slot number.

For NMEA-based backends the satellite identifier can be used to determine the satellite system type if it is not available from other sources. You can refer to \l {https://gpsd.gitlab.io/gpsd/NMEA.html#_satellite_ids} {satellite IDs list} to check the ID ranges for different satellite systems.

Note: Depending on the platform and the selected backend, the satellite identifier ranges for different satellite systems may intersect. To uniquely identify a satellite, a combination of satelliteIndetifier() and \l satelliteSystem() must be used.

See also: satelliteSystem()

Definition at line 210 of file qgeosatelliteinfo.cpp.

◆ satelliteSystem()

QGeoSatelliteInfo::SatelliteSystem QGeoSatelliteInfo::satelliteSystem ( ) const

Returns the Satellite System (GPS, GLONASS, ...)

Note: This value can be used together with \l satelliteIdentifier() to uniquely identify a satellite.

See also: satelliteIdentifier()

Definition at line 159 of file qgeosatelliteinfo.cpp.

◆ setAttribute()

void QGeoSatelliteInfo::setAttribute	(	Attribute	attribute,
		qreal	value )

Sets the value for attribute to value.

Definition at line 235 of file qgeosatelliteinfo.cpp.

◆ setSatelliteIdentifier()

void QGeoSatelliteInfo::setSatelliteIdentifier ( int satId )

Sets the satellite identifier number to satId.

The satellite identifier number can be used to identify a satellite within the satellite system.

The actual value may vary, depending on the platform and the selected backend.

For example, if nmea plugin is used, the satellite identifier for GPS satellite system represents the PRN (Pseudo-random noise) number, and the satellite identifier for GLONASS satellite system represents the slot number.

Definition at line 178 of file qgeosatelliteinfo.cpp.

◆ setSatelliteSystem()

void QGeoSatelliteInfo::setSatelliteSystem ( SatelliteSystem system )

Sets the Satellite System (GPS, GLONASS, ...) to system.

Definition at line 145 of file qgeosatelliteinfo.cpp.
