GNSS and GPS Attenuators


A GNSS or GPS attenuator is a passive device designed to reduce the strength of GNSS signals transmitted from satellites. These attenuators adjust the signal power levels to match the requirements of GNSS receivers. GNSS attenuators are widely used in receiver testing and calibration procedures to simulate different signal strength levels and environmental conditions. By adjusting the signal power levels, attenuators enable accurate testing of GNSS receivers' performance under various scenarios, such as weak signal reception or signal interference.
