Disclosed is a system for using an antenna array in conjunction with a GPS receiver to receive GPS satellite transmissions. A switching circuit, under the control of a GPS controller, can vary the sampling rate of multiple antennas in the antenna array to ensure that multiple satellite information is acquired. The device of the present invention can be implemented in handheld cell phones, personal data assistants, telemetric devices or any device using a GPS receiver that may be used in various orientations so as to receive GPS satellite transmissions from multiple directions. More highly directional antennas can be employed having higher gain since the antenna array can receive satellite data from multiple orientations.
