Real lupnt::FreeSpacePathLoss(Real dist, Real freq)¶

Compute the free-space path loss for a link of a given range and signal frequency.

Used by the internal LinkBudget helper in gnss_measurement.cc (called from GNSSMeasurements::ComputeCN0) to convert the transmitter-to-receiver range into a loss term subtracted from the link budget when estimating CN0.

Parameters:

dist – Slant range between transmitter and receiver [m]
freq – Signal frequency [Hz]

Returns:

Free-space path loss [dB]
