Abstract
The present invention utilizes signals such as interrogate commands generated from a Master Clock or other High Precision Clocks in a distributed sensor data acquisition system featuring a communications network (such as a land/transition zone seismic data acquisition system) to stabilize the oscillator (timing cycle) frequency of Remote Clocks elsewhere in the network. The disclosed invention is characterized by the utilization of highly stable timing signals from a Master Clock or other High Precision Clocks as a calibration standard to improve the oscillator frequency of distributed Remote Clocks of lesser inherent stability. Implementation of the disclosed invention results in improved synchronization of seismic amplitude data concurrently acquired over a wide area and improved subsurface geologic resolution.
