Method Summary

Methods

Modifier and Type	Method and Description
double	calculatePathDelay(double elevation, double height) Calculates the tropospheric path delay for the signal path from a ground station to a satellite.
double	calculateSignalDelay(double elevation, double height) Calculates the tropospheric signal delay for the signal path from a ground station to a satellite.

Method Detail

calculatePathDelay

double calculatePathDelay(double elevation,
                        double height)

Calculates the tropospheric path delay for the signal path from a ground station to a satellite.

Parameters:

elevation - the elevation of the satellite in degrees

height - the height of the station in m above sea level

Returns:

the path delay due to the troposphere in m

calculateSignalDelay

double calculateSignalDelay(double elevation,
                          double height)

Calculates the tropospheric signal delay for the signal path from a ground station to a satellite. This method exists only for convenience reasons and returns the same as

   SaastamoinenModel.calculatePathDelay(double, double)/Constants.SPEED_OF_LIGHT
 

Parameters:

elevation - the elevation of the satellite in degrees

height - the height of the station in m above sea level

Returns:

the signal delay due to the troposphere in s
