METHOD AND SYSTEM FOR ANTENNA DIVERSITY WITH GLOBAL NAVIGATION SATELLITE SYSTEMS (GNSS)

摘要

A wireless device including one or more receivers may selectively couple one or more antennas to one or more receivers based on a directionality of the antennas and an orientation of the antennas with respect to sources of the received wireless signals, which may include global navigation satellite system (GNSS) signals. The orientation may be determined utilizing orientation sensors integrated in the wireless device, and may include a MEMS sensor and/or a magnetic compass. The antennas may be selectively coupled to the receivers based on a location of the wireless sources and the orientation of the directionality with respect to sources of the received wireless signals. A received signal strength indicator (RSSI) may be measured for each configuration. The antennas may be coupled sequentially to the receivers to determine a maximum of the RSSI. The antennas may include patch antennas and/or dipole antennas.
