Detailed Description

The static function createDefaultSource() creates a default satellite data source that is appropriate for the platform, if one is available. Otherwise, available QGeoPositionInfoSourceFactory plugins will be checked for one that has a satellite data source available.

Call startUpdates() and stopUpdates() to start and stop regular updates, or requestUpdate() to request a single update. When an update is available, satellitesInViewUpdated() and/or satellitesInUseUpdated() will be emitted.

If regular satellite updates are required, setUpdateInterval() can be used to specify how often these updates should be emitted. If no interval is specified, updates are simply provided whenever they are available. For example:

// Emit updates every 10 seconds if available
QGeoSatelliteInfoSource *source = QGeoSatelliteInfoSource::createDefaultSource(0);
if (source)
    source->setUpdateInterval(10000);

To remove an update interval that was previously set, call setUpdateInterval() with a value of 0.

Note

The satellite source may have a minimum value requirement for update intervals, as returned by minimumUpdateInterval() .

class PySide6.QtPositioning.QGeoSatelliteInfoSource(parent)

Parameters

parent – PySide6.QtCore.QObject

PySide6.QtPositioning.QGeoSatelliteInfoSource.Error

The Error enumeration represents the errors which can occur.

Constant	Description
QGeoSatelliteInfoSource.AccessError	The connection setup to the satellite backend failed because the application lacked the required privileges.
QGeoSatelliteInfoSource.ClosedError	The satellite backend closed the connection, which happens for example in case the user is switching location services to off. This object becomes invalid and should be deleted. A new satellite source can be created by calling createDefaultSource() later on.
QGeoSatelliteInfoSource.NoError	No error has occurred.
QGeoSatelliteInfoSource.UnknownSourceError	An unidentified error occurred.
QGeoSatelliteInfoSource.UpdateTimeoutError	The current satellite information could not be retrieved within the specified timeout.

static PySide6.QtPositioning.QGeoSatelliteInfoSource.availableSources()

Return type

list of strings

Returns a list of available source plugins, including the default system backend if one is available.

PySide6.QtPositioning.QGeoSatelliteInfoSource.backendProperty(name)

Parameters

name – str

Return type

object

Returns the value of the backend-specific property named name, if present. Otherwise the returned value will be invalid.

static PySide6.QtPositioning.QGeoSatelliteInfoSource.createDefaultSource(parameters, parent)

Parameters

• parameters –

• parent – PySide6.QtCore.QObject

Return type

PySide6.QtPositioning.QGeoSatelliteInfoSource

Creates and returns a satellite source with the given parent that reads from the system’s default sources of satellite data, or the plugin with the highest available priority.

Returns nullptr if the system has no default satellite source, no valid plugins could be found or the user does not have the permission to access the satellite information.

This method passes parameters to the factory to configure the source.

static PySide6.QtPositioning.QGeoSatelliteInfoSource.createDefaultSource(parent)

Parameters

parent – PySide6.QtCore.QObject

Return type

PySide6.QtPositioning.QGeoSatelliteInfoSource

Creates and returns a source with the specified parent that reads from the system’s default source of satellite update information, or the highest priority available plugin.

Returns nullptr if the system has no default satellite source, no valid plugins could be found or the user does not have the permission to access the satellite data.

static PySide6.QtPositioning.QGeoSatelliteInfoSource.createSource(sourceName, parent)

Parameters

• sourceName – str

• parent – PySide6.QtCore.QObject

Return type

PySide6.QtPositioning.QGeoSatelliteInfoSource

Creates and returns a source with the given parent, by loading the plugin named sourceName.

Returns nullptr if the plugin cannot be found.

static PySide6.QtPositioning.QGeoSatelliteInfoSource.createSource(sourceName, parameters, parent)

Parameters

• sourceName – str

• parameters –

• parent – PySide6.QtCore.QObject

Return type

PySide6.QtPositioning.QGeoSatelliteInfoSource

Creates and returns a satellite source with the given parent, by loading the plugin named sourceName.

Returns nullptr if the plugin cannot be found.

This method passes parameters to the factory to configure the source.

PySide6.QtPositioning.QGeoSatelliteInfoSource.error()

Return type

Error

Returns the last error that occurred.

Note

Since Qt6 the last error is always reset when calling startUpdates() or requestUpdate() .

PySide6.QtPositioning.QGeoSatelliteInfoSource.errorOccurred(arg__1)

Parameters

arg__1 – Error

PySide6.QtPositioning.QGeoSatelliteInfoSource.minimumUpdateInterval()

Return type

int

This property holds This property holds the minimum time (in milliseconds) required to retrieve a satellite update..

This is the minimum value accepted by setUpdateInterval() and requestUpdate() .

PySide6.QtPositioning.QGeoSatelliteInfoSource.requestUpdate([timeout=0])

Parameters

timeout – int

Attempts to get the current satellite information and emit satellitesInViewUpdated() and satellitesInUseUpdated() with this information. If the current satellite information cannot be found within the given timeout (in milliseconds) or if timeout is less than the value returned by minimumUpdateInterval() , an errorOccurred() signal with UpdateTimeoutError is emitted.

If the timeout is zero, the timeout defaults to a reasonable timeout period as appropriate for the source.

This does nothing if another update request is in progress. However it can be called even if startUpdates() has already been called and regular updates are in progress.

Note

Since Qt6 this method always resets the last error to NoError before requesting the satellite information.

PySide6.QtPositioning.QGeoSatelliteInfoSource.satellitesInUseUpdated(satellites)

Parameters

satellites –

PySide6.QtPositioning.QGeoSatelliteInfoSource.satellitesInViewUpdated(satellites)

Parameters

satellites –

PySide6.QtPositioning.QGeoSatelliteInfoSource.setBackendProperty(name, value)

Parameters

• name – str

• value – object

Return type

bool

Sets the backend-specific property named name to value. Returns true on success, false otherwise. Backend-specific properties can be used to configure the satellite info subsystem behavior at runtime.

backendProperty

PySide6.QtPositioning.QGeoSatelliteInfoSource.setUpdateInterval(msec)

Parameters

msec – int

This property holds This property holds the requested interval in milliseconds between each update..

If the update interval is not set (or is set to 0) the source will provide updates as often as necessary.

If the update interval is set, the source will provide updates at an interval as close to the requested interval as possible. If the requested interval is less than the minimumUpdateInterval() , the minimum interval is used instead.

Changes to the update interval will happen as soon as is practical, however the time the change takes may vary between implementations. Whether or not the elapsed time from the previous interval is counted as part of the new interval is also implementation dependent.

The default value for this property is 0.

Note

Subclass implementations must call the base implementation of so that returns the correct value.

PySide6.QtPositioning.QGeoSatelliteInfoSource.sourceName()

Return type

str

Returns the unique name of the satellite source implementation in use.

This is the same name that can be passed to createSource() in order to create a new instance of a particular satellite source implementation.

PySide6.QtPositioning.QGeoSatelliteInfoSource.startUpdates()

Starts emitting updates at regular intervals. The updates will be provided whenever new satellite information becomes available.

If satellite information cannot be retrieved or some other form of timeout has occurred the satellitesInViewUpdated() and satellitesInUseUpdated() signals may be emitted with empty parameter lists.

Note

Since Qt6 this method always resets the last error to NoError before starting the updates.
