Member Function Documentation

get_attenuation()

double AtmosphericGasesITU::get_attenuation ( )

virtual

Get the estimated attenuation. This pure virtual function MUST be implemented by every derived class.

Returns

the attenuation in dB.

Method is only valid for elevation angles above 1 degree

Iterate through all atmoshpere layers up to 100km. Each layer has height that exponentially grows from 10cm to 1km TODO: Initial altitude should be related to Ground Station altitude

Estimate temperature and pressure for the current atmospheric layer.

Ignore some NaN TODO: Investigate this issue

Implements GenericAttenuation.
