gain to noise temperature (G/T)

Gain to Noise Temperature (G/T) is the ratio of gain to temperature-dependent noise and describes the efficiency of satellite receivers and transponders

. The gain-to-noise value is also referred to as the reception quality factor. Gain (G) is the total gain

indecibels and "T" is the noise temperature in decibels, related to 10 Kelvin

. The lower the G/T ratio, the better the reception conditions of satellites. In addition, the G/T value indicates the quality of parabolic antennas. Satellite operators publish G/T maps showing the transmission conditions from ground stations to the satellite.
