int GPSBearingCalculator::DataClass::ApplyLowPassFilter	(	const int	previousValue,
		const int	nextValue
	)		const

ApplyLowPassFilter - apply simple first order low-pass filter with fixed coefficient.

Here is the caller graph for this function:

int GPSBearingCalculator::DataClass::CalculateAverageAngleInCircle ( const QVector< double > calculatedBearings ) const

CalculateAverageAngleInCircle - calculate average angle from multiple angles in circle.

Note: we cannot use simple average - angles can be in interval <0,360> => difference between 10° and 350° is -20°

Here is the caller graph for this function:

int GPSBearingCalculator::DataClass::CalculateBearing ( QQueue< CalculationPoint > & receivedPoints )

CalculateBearing - calculate bearing (angle from true north) from collection of positions.

Parameters

receivedPoints - collection of positions

Here is the call graph for this function:

double GPSBearingCalculator::DataClass::CalculateBearingForTwoPositions	(	const CalculationPoint &	firstPosition,
		const CalculationPoint &	secondPosition
	)		const

CalculateBearingForTwoPositions - calculates bearing (angle from true north) between two positions.

Parameters

firstPosition
secondPosition

Here is the caller graph for this function:

double GPSBearingCalculator::DataClass::DifferenceBetweenTwoAnglesInCircle	(	const double	first,
		const double	second
	)		const

DifferenceBetweenTwoAngles - calculate difference between two angles in circle.
