Enumeration Type Documentation

IonosphereModel

enum class NAV::IonosphereModel : int

strong

Available Ionosphere Models.

Enumerator
None	Ionosphere model turned off.
Klobuchar	Klobuchar model (GPS), also called Broadcast sometimes.
COUNT	Amount of items in the enum.

Function Documentation

calcIonosphericDelay()

double NAV::calcIonosphericDelay	(	double	tow,
		Frequency	freq,
		int8_t	freqNum,
		const Eigen::Vector3d &	lla_pos,
		double	elevation,
		double	azimuth,
		IonosphereModel	ionosphereModel = IonosphereModel::None,
		const IonosphericCorrections *	corrections = nullptr )

Calculates the ionospheric delay.

Parameters

[in]	tow	GPS time of week in [s]
[in]	freq	Frequency of the signal
[in]	freqNum	Frequency number. Only used for GLONASS G1 and G2
[in]	lla_pos	[𝜙, λ, h]^T Geodetic latitude, longitude and height in [rad, rad, m]
[in]	elevation	Angle between the user and satellite [rad]
[in]	azimuth	Angle between the user and satellite, measured clockwise positive from the true North [rad]
[in]	ionosphereModel	Ionosphere model to use
[in]	corrections	Ionospheric correction parameters

Returns

Ionospheric time delay in [m]

ComboIonosphereModel()

bool NAV::ComboIonosphereModel	(	const char *	label,
		IonosphereModel &	ionosphereModel )

Shows a ComboBox to select the ionosphere model.

Parameters

[in]	label	Label to show beside the combo box. This has to be a unique id for ImGui.
[in]	ionosphereModel	Reference to the ionosphere model to select

ionoErrorVar()

double NAV::ionoErrorVar	(	double	dpsr_I,
		Frequency	freq,
		int8_t	num )

Calculates the ionospheric error variance.

Parameters

[in]	dpsr_I	Ionosphere propagation error [m]
[in]	freq	Frequency
[in]	num	Frequency number. Only used for GLONASS G1 and G2

Returns

Variance of the error [m^2]

to_string()

const char * NAV::to_string

(

IonosphereModel

ionosphereModel

)

Converts the enum to a string.

Parameters

[in]

ionosphereModel

Enum value to convert into text

Returns

String representation of the enum
