GPS /GLONASS Signal Re-radiater for Indoor Satellites Signal Reception

Product Name :
GPS /GLONASS Signal Re-radiater for Indoor Satellites Signal Reception
Model No :


RK-306 is a complete GPS/GLONASS L1 band signal re-radiating system with dual antennas to re-transmit real-time GPS/GLONASS satellite outdoor reception to an indoor environment. The system kits include a high gain external GPS /GLONASS 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 GPS/GLONASS receivers perform on-the-fly receiver performance within a closed environment, while the main GPS/GLONASS  antenna is located on an unmanned outdoor location. GPS/GLONASS center frequency is1590MHz. The input signal power at the receiving antenna is approximately -130dBm, 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.

Wherever in lab/building/underground garage, RK-306 guarantees to bring and re-radiate GPS/GLONASS signal that meets your requirement.
