Detailed Description

A representation of a satellite in Earth orbit.

Details about the satellite are passed with a JSON-representation structure that contains a Satellite Catalog entry.

Thanks to operator<() overloading, container classes (QList, QMap, etc) with Satellite or SatelliteP objects can be sorted by satellite name/ID.

Definition at line 91 of file Satellite.hpp.

Member Enumeration Documentation

enum Satellite::OptStatus

operational statuses

Definition at line 100 of file Satellite.hpp.

Constructor & Destructor Documentation

Satellite::Satellite	(	const QString &	identifier,
		const QVariantMap &	data
	)

Parameters

identifier	unique identifier (currently the Catalog Number)
data	a QMap which contains the details of the satellite (TLE set, description etc.)

Member Function Documentation

float Satellite::calculateIlluminatedFraction ( ) const

Calculation of illuminated fraction of the satellite.

virtual double Satellite::getAngularSize ( const StelCore * core ) const

virtual

Return the angular radius of a circle containing the object as seen from the observer with the circle center assumed to be at getJ2000EquatorialPos().

Returns: radius in degree. This value is the apparent angular size of the object, and is independent of the current FOV.

Implements StelObject.

QString Satellite::getCatalogNumberString ( ) const

inline

Returns the (NORAD) catalog number. (For now, the ID string.)

Definition at line 167 of file Satellite.hpp.

virtual QString Satellite::getEnglishName ( void ) const

inlinevirtual

Return object's name in english.

Implements StelObject.

Definition at line 162 of file Satellite.hpp.

SatFlags Satellite::getFlags ( )

Get internal flags as a single value.

virtual Vec3f Satellite::getInfoColor ( void ) const

virtual

Get a color used to display info about the object.

Reimplemented from StelObject.

virtual QVariantMap Satellite::getInfoMap ( const StelCore * core ) const

virtual

Return a map like StelObject::getInfoMap(), but with a few extra tags also available in getInfoString().

virtual QString Satellite::getInfoString	(	const StelCore *	core,
		const InfoStringGroup &	flags
	)		const

virtual

Get an HTML string to describe the object.

Parameters

core	A pointer to the core
flags	a set of flags with information types to include. Supported types for Satellite objects: Name: designation in large type with the description underneath RaDecJ2000, RaDecOfDate, HourAngle, AltAzi Extra: range, range rate and altitude of satellite above the Earth, comms frequencies, modulation types and so on.

Implements StelObject.

virtual Vec3d Satellite::getJ2000EquatorialPos ( const StelCore * core ) const

virtual

Get observer-centered equatorial coordinates at equinox J2000.

Implements StelObject.

QVariantMap Satellite::getMap ( void )

Get a QVariantMap which describes the satellite.

Could be used to create a duplicate.

virtual QString Satellite::getNameI18n ( void ) const

virtual

Return translated object's name.

Implements StelObject.

QString Satellite::getOperationalStatus ( ) const

Get operational status of satellite.

virtual float Satellite::getSelectPriority ( const StelCore * ) const

virtual

Return a priority value which is used to discriminate objects by priority As for magnitudes, the lower is the higher priority.

Reimplemented from StelObject.

virtual QString Satellite::getType ( void ) const

inlinevirtual

Return object's type. It should be the name of the class.

Implements StelObject.

Definition at line 122 of file Satellite.hpp.

virtual float Satellite::getVMagnitude ( const StelCore * core ) const

virtual

Return object's apparent V magnitude as seen from observer, without including extinction.

Reimplemented from StelObject.

bool Satellite::operator< ( const Satellite & another ) const

Needed for sorting lists (if this ever happens...).

Compares #name fields. If equal, #id fields, which can't be.

void Satellite::parseInternationalDesignator ( const QString & tle1 )

Parse TLE line to extract International Designator and launch year.

Sets #internationalDesignator and #jdLaunchYearJan1.

void Satellite::setFlags ( const SatFlags & flags )

Sets the internal flags in one operation (only display flags)!

void Satellite::setNewTleElements	(	const QString &	tle1,
		const QString &	tle2
	)

Set new tleElements.

This assumes the designation is already set, populates the tleElements values and configures internal orbit parameters.
