RK-20W is a comprehensive GNSS (GPS/GLONASS/BEIDOU/GALILEO and QZSS) re-radiating system equipped with dual antennas for transmitting real-time GNSS satellite signals from an outdoor setting to an indoor environment.

The kit consists of a high gain external multiband antenna, a precisely calibrated amplifier circuit featuring a ceramic patch re-radiator, and a power supply regulator. With the ceramic patch re-radiator, multiple GNSS receivers can achieve optimal performance within a confined space, while the main GNSS antenna is positioned in an unmanned outdoor location. Usually, this would be mounted on a roof.

The entire system is designed as Plug-and-Play (PNP) hardware.
