Detailed Description

Member Type Documentation

 

enum QGeoSatelliteInfo::Attribute

Defines the attributes for the satellite information.

Constant

Value

Description

QGeoSatelliteInfo::Elevation

0

The elevation of the satellite, in degrees.

QGeoSatelliteInfo::Azimuth

1

The azimuth to true north, in degrees.

enum QGeoSatelliteInfo::SatelliteSystem

Defines the GNSS system of the satellite.

Constant

Value

Description

QGeoSatelliteInfo::Undefined

0x00

Not defined.

QGeoSatelliteInfo::GPS

0x01

Global Positioning System (USA).

QGeoSatelliteInfo::GLONASS

0x02

Global Positioning System (Russia).

QGeoSatelliteInfo::GALILEO

0x03

Global navigation satellite system (EU).

QGeoSatelliteInfo::BEIDOU

0x04

BeiDou navigation satellite system (China).

QGeoSatelliteInfo::QZSS

0x05

Quasi-Zenith Satellite System (Japan).

QGeoSatelliteInfo::Multiple

0xFF

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.

QGeoSatelliteInfo::CustomType

0x100

The first type that can be used for user purposes. For example when reimplementing NMEA data parsing in QNmeaSatelliteInfoSource. User can add more types using CustomType + 1, CustomType + 2 and so on.

Member Function Documentation

 

QGeoSatelliteInfo::QGeoSatelliteInfo()

Creates a satellite information object.

QGeoSatelliteInfo::QGeoSatelliteInfo(const QGeoSatelliteInfo &other)

Creates a satellite information object with the values of other.

[since 6.2] QGeoSatelliteInfo::QGeoSatelliteInfo(QGeoSatelliteInfo &&other)

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.

This function was introduced in Qt 6.2.

QGeoSatelliteInfo::~QGeoSatelliteInfo()

Destroys a satellite information object.

qreal QGeoSatelliteInfo::attribute(QGeoSatelliteInfo::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

See also hasAttribute(), setAttribute()

bool QGeoSatelliteInfo::hasAttribute(QGeoSatelliteInfo::Attribute attribute) const

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

void QGeoSatelliteInfo::removeAttribute(QGeoSatelliteInfo::Attribute attribute)

Removes the specified attribute and its value.

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 satellite IDs list to check the ID ranges for different satellite systems.

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 satelliteSystem() must be used.

Getter function for property satelliteIdentifier.

See Also

QGeoSatelliteInfo::SatelliteSystem QGeoSatelliteInfo::satelliteSystem() const

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

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

Getter function for property satelliteSystem.

See Also

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

Sets the value for attribute to value.

See Also

See also attribute()

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.

See also satelliteIdentifier()

void QGeoSatelliteInfo::setSatelliteSystem(QGeoSatelliteInfo::SatelliteSystem system)

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

See Also

See also satelliteSystem()

void QGeoSatelliteInfo::setSignalStrength(int signalStrength)

Sets the signal strength to signalStrength, in decibels.

See Also

See also signalStrength()

int QGeoSatelliteInfo::signalStrength() const

Returns the signal strength, or -1 if the value has not been set.

Getter function for property signalStrength.

See Also

See also setSignalStrength()

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

Assigns the values from other to this object.

[since 6.2] QGeoSatelliteInfo &QGeoSatelliteInfo::operator=(QGeoSatelliteInfo &&other)

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.

This function was introduced in Qt 6.2.

bool operator!=(const QGeoSatelliteInfo &lhs, const QGeoSatelliteInfo &rhs)

Returns true if any of the parameters of the lhs satellite are not the same as those of rhs. Otherwise returns false.

QDataStream &operator<<(QDataStream &stream, const QGeoSatelliteInfo &info)

Writes the given info to the specified stream.

See Also

bool operator==(const QGeoSatelliteInfo &lhs, const QGeoSatelliteInfo &rhs)

Returns true if all the parameters of the lhs satellite are the same as those of rhs. Otherwise returns false.

QDataStream &operator>>(QDataStream &stream, QGeoSatelliteInfo &info)

Reads satellite information from the specified stream into the given info.
