Abstract

A system to control the orientation of a seismic source includes a signal processor that receives an input signal from a compass to provide an input orientation for the vibrator control electronics of an omnidirectional shear wave source. By orienting the signal generation in this manner, the need to orient the truck is obviated without negatively impacting the quality of the data. The signal processor can be eliminated if the compass output signal is already in a form that can be used by the vibrator control electronics.
