Abstract: Systems and methods for providing Fine Time Assistance (FTA) and Power Amplifier (PA) Blanking to a Global Navigation Satellite System (GNSS) module are provided. In an embodiment, FTA is provided in a communications device having a GNSS module and a cellular communications module, where the cellular communications module is configured to receive a reference time, transmit a pulse to the GNSS module at a pulse generation time, and provide a compensated reference time based on the pulse generation time to the GNSS module. In another embodiment, PA blanking is provided in a communications device having a GNSS module and a cellular communications module, where the cellular communications module is configured to transmit a pulse to the GNSS module to signal a high cellular-to-GNSS interference time period.
