Abstract: A method for correcting physical positions of seismic sensors and/or seismic sources for a seismic data acquisition system. The method includes estimating a respective energy generated by each source element, which belongs to a source array; calculating a respective energy recorded by each individual seismic sensor, which belongs to a composite receiver; summing, for each individual seismic sensor, all the generated energies from the all the source elements; estimating a model of direct arrival waves that propagate from the source elements to the individual seismic sensors; calculating positions of the individual seismic sensors based on the model of direct arrival waves; comparing calculated positions of the individual seismic sensors with observed positions of the individual seismic sensors; selecting a best calculated position for each of the individual seismic sensors based on an objective function; and correcting the observed positions of the individual seismic sensors with corresponding best calculated positions.
