Abstract
The system includes a reconfigurable GNSS antenna subsystem that dynamically reconfigures one or more antenna parameters to change one or more operating characteristics of an antenna based on environmental conditions and/or the presence of interfering signals to improve the quality of GNSS satellite signal reception. The system analyzes the received signals to determine if the GNSS satellite signals are sufficiently above received noise, if interfering signals are present, and/or if multipath signals are adversely impacting position calculations. Based on the analysis, the reconfigurable antenna subsystem selectively and dynamically reconfigures one or more parameters to change one or more operating characteristics of the antenna. As the conditions change, the reconfigurable antenna subsystem may dynamically reconfigure one or more of the antenna parameters accordingly.
