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 Car tracking device, Locator application, safety alarm device, personal locator and digital
camera.
Product Features
