Introduction
SBG-190 is are-radiating equipment. It can receive the outdoor GPS satellite signal and conduct to indoor place for radiating again. When a GPS Satellite is revolving around the earth it will transmit continuously satellite signal to the earth, but the strength of satellite signal will weaken to only around -125dBm when it arrived to the earth ground. Such weak signal can't penetrate into buildings or vehicles; besides, its reflection or scattering signal can be detected only in around windows area. SBG-190 is built for the purpose to transmit the GPS satellite signal from outdoor to indoor, and re-radiating the receptions for multi-users to operate GPS Receivers inside buildings or vehicles. SBG-190 contents a power regulation circuit, a high frequency low noise amplifier, a signal radiation set, and an active outdoor antenna to receive the GPS satellite signal.
