RGM-2106 Operational Manual 1 Introduction RoyalTek RGM-2106 is the smart antenna GPS module with SiRFstar IV GPS solution. The module embedded active Jammer remover to ensure fast and accurate navigation in hostile signal/high noise environment. Power by the new SiRFStar IV architecture, the module can acquire satellites as low as -163dBm better than SiRF Star III. The high sensitivity, low power, 48-channel GPS module is the best choice to be embedded in a portable device such as Ca
