Various embodiments of the present technology generally relate to Global Navigation Satellite Systems (GNSS). More specifically, the embodiments of the present technology relate to a smart antenna module resistant to Radio Frequency Interference (RFI) saturation for dual-frequency GNSS receivers. In some embodiments, a dynamically configured antenna module architecture can be for a dual-band (or multi-frequency) GNSS receiver that can adapt to different RFI conditions by performing corresponding working modes. For example, some embodiments of the smart antenna can measure (e.g., using a power detector) the power of an incoming multi-frequency signal to determine when the multifrequency signal is saturated. Then, using control logic the smart antenna can determine which frequency in the multi-frequency signal is usable and isolate (e.g. using radio frequency components) a frequency that is not saturated. A position estimate can then be generated based on the isolated multi-frequency signal.
