RK-20W is a complete GNSS (GPS/GLONASS/BEIDOU/GALILEO and QZSS) re-radiating system with dual antennas to re-transmit real-time GNSS satellite outdoor reception to an indoor environment. The system kits include a high gain external GPS/GLONASS/BEIDOU/GALILEO and QZSS antenna, a precisely calibrated amplifier circuit with ceramic patch re-radiator, and a built-in power supply regulator. The ceramic patch re-radiator allows multiple GNSS receivers perform on-the-fly receiver performance within a closed environment, while the main GNSS antenna is located on an unmanned outdoor location. The input signal power at the receiving antenna is approximately -130dBm (spreading over 2 MHz), so the desire signal is below the thermal noise floor. The whole system is designed as PNP (Plug-and-Play) hardware and it can be installed either temporarily or permanently to a secured location by using whether dashboard suction cup or screws.
