Detailed Description

The Satellites class is the main class of the plug-in. It manages a collection of Satellite objects and takes care of loading, saving and updating the satellite catalog. It allows automatic updates from online sources and manages a list of update file URLs.

To calculate satellite positions, the plugin uses an implementation of the SGP4/SDP4 algorithms (J.L. Canales' gsat library).

Satellite Properties

Name and identifiers

Each satellite has a name. It's displayed as a label of the satellite hint and in the list of satellites. Names are not unique though, so they are used only for presentation purposes.

In the Satellite Catalog satellites are uniquely identified by their NORAD number, which is encoded in TLEs.

Grouping

A satellite can belong to one or more groups such as "amateur", "geostationary" or "navigation". They have no other function but to help the user organize the satellite collection.

Group names are arbitrary strings defined in the Satellite Catalog for each satellite and are more similar to the concept of "tags" than a hierarchical grouping. A satellite may not belong to any group at all.

By convention, group names are in lowercase. The GUI translates some of the groups used in the default catalog.

Satellite Catalog

The satellite catalog is stored on the disk in JSON format, in a file named "satellites.json". A default copy is embedded in the plug-in at compile time. A working copy is kept in the user data directory.

Configuration

The plug-ins' configuration data is stored in Stellarium's main configuration file.

Property Documentation

◆ filterFlag

SatFlag SatellitesListFilterModel::filterFlag
readwrite

Use Satellite::NoFlags for no filtering. Setting the flag with setFilterFlag() or setSecondaryFilters() will cause the model to be re-filtered.

◆ filterGroup

QString SatellitesListFilterModel::filterGroup
readwrite

Use an empty group ID for no filtering. Setting the group with setFilterGroup() or setSecondaryFilters() will cause the model to be re-filtered.

◆ SatellitesListModel

class SatellitesListModel

Used for GUI presentation purposes.

It can show satellite names in their hint colors. This behavior can be toggled with enableColoredNames(), e.g. to honor night mode.

Warning
The model keeps a pointer to the satellite list, not a copy, so every time that list is modified outside the model (i.e. satellites are added or removed), you need to call beginSatellitesChange() and endSatellitesChange().

◆ beginSatellitesChange

void SatellitesListModel::beginSatellitesChange ( )
slot

This should be called every time when the underlying data structure is about to be modified outside the model! (That is, when satellites are about to be added or removed.) Otherwise views that use this model won't work correctly.

◆ endSatellitesChange

void SatellitesListModel::endSatellitesChange ( )

Don't call this without calling beginSatellitesChange() first! This should be called every time when the underlying data structure has been modified outside the model! (That is, when satellites have been added or removed.) Otherwise views that use this model won't work correctly.

Member Function Documentation

◆ getID()

virtual QString Satellite::getID ( void  ) const
inlinevirtual

The ID should be unique for all objects of the same type, but may freely conflict with IDs of other types, so getType() must also be tested.

With this it should be possible to at least identify the same object in a different instance of Stellarium running the same version, but it would even be better if the ID provides some degree of forward-compatibility. For some object types (e.g. planets) this may simply return getEnglishName(), but better candidates may be official designations or at least (stable) internal IDs.

An object may have multiple IDs (different catalog numbers, etc). StelObjectMgr::searchByID() should search through all ID variants, but this method only returns one of them.

addedthe number of newly added satellites;
missingthe number of satellites that were not found in the update source(s) (and were removed, if autoRemoveEnabled is set).

◆ update()

virtual void Satellites::update ( double  deltaTime)
virtual
Parameters
deltaTimethe time increment in second since last call.

Reimplemented from StelModule.

◆ updateFromFiles()

void Satellites::updateFromFiles ( QStringList  paths,
bool  deleteFiles = false 
)

Indirectly emits signals updateStateChanged() and tleUpdateComplete(), as it calls updateSatellites(). See updateFromOnlineSources() for the other kind of update operation.

Parameters
pathsa list of paths to update files
deleteFilesif set, the update files are deleted after they are used, else they are left alone

◆ updateFromOnlineSources

void Satellites::updateFromOnlineSources ( )
slot

This method starts the process of an Internet update: it tries to download TLE lists from online resources and then use them to update the orbital data (and names, etc.) of the included satellites. This only initialized the download. The rest of the work is done by saveDownloadedUpdate() and updateSatellites(). Update sources are described in updateUrls (see for accessors details). If autoAddEnabled is true when this function is called, new satellites in the chosen update sources will be added during the update. If autoRemoveEnabled is true when this function is called, any existing satellite that can't be found in the downloaded update lists will be removed. See updateFromFiles() for the other type of update operation.

◆ updateSatellites()

void Satellites::updateSatellites ( TleDataHash &  newTleSets)

Worker function called by updateFromFiles() and saveDownloadedUpdate(). (Respectively, user-initiated update from file(s) and user- or auto- initiated update from online source(s).) Emits updateStateChanged() and tleUpdateComplete().

Note
Instead of splitting this method off updateFromFiles() and passing the auto-add flag through data structures, another possibility was to modify updateFromFiles to use the same prefix trick (adding "1," to file paths). I decided against it because I thought it would be more complex. :) –BM
Parameters
[in,out]newTleSetsa hash with satellite IDs as keys; it's modified by the method!

◆ updateStateChanged

void Satellites::updateStateChanged ( Satellites::UpdateState  state)
signal

when an update starts, completes and so on. Note that on completion of an update, tleUpdateComplete is also emitted with the number of updates done.

Parameters
statethe new update state.

Property Documentation

◆ autoAddEnabled

bool Satellites::autoAddEnabled

This will apply only for the selected update sources.
