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. |
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.

[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.
Creates a satellite information object with the values of other.
Creates a satellite information 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.
Assigns the values from other to this object.
Destroys a satellite information object.
Returns the value of the specified attribute as a qreal value.
Returns -1 if the value has not been set.
See also hasAttribute() and setAttribute().
Returns true if the specified attribute is present in this update.
Removes the specified attribute and its value.
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.
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 satelliteSystem() must be used.
See also setSatelliteIdentifier() and satelliteSystem().
Returns the Satellite System (GPS, GLONASS, ...)
Note: This value can be used together with satelliteIdentifier() to uniquely identify a satellite.
See also setSatelliteSystem() and satelliteIdentifier().
Sets the value for attribute to value.
See also attribute().
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().
Sets the Satellite System (GPS, GLONASS, ...) to system.
See also satelliteSystem().
Sets the signal strength to signalStrength, in decibels.
See also signalStrength().
Returns the signal strength, or -1 if the value has not been set.
See also setSignalStrength().
Returns true if any of the parameters of the lhs satellite are not the same as those of rhs. Otherwise returns false.
Writes the given info to the specified stream.
See also Serializing Qt Data Types.
Returns true if all the parameters of the lhs satellite are the same as those of rhs. Otherwise returns false.
Reads satellite information from the specified stream into the given info.
See also Serializing Qt Data Types.
