1. method that is used to control the seismic surveying spread comprises:

  • Collect the input data from seismic surveying spread, comprising with a plurality of spread control elements, a plurality of navigation node and a plurality of focus and receiver;

    The aeronautical data of navigation node,From with the mode of operation of spread control element sensor associated,The environmental data that is used to measure, andMeasure design data;

    Use aeronautical data, mode of operation and environmental data to estimate the position of focus and receiver;

    A position of use estimating and a part that comprises the input data of measuring design data are at least confirmed the best trace of focus and receiver;

    Wherein best trace is confirmed according to the weighting function in the translation function;

    Weighting function receives the position of measurement design data and estimation as input;

    Relative weighting coefficient is applied to input;

    Through confirming best spread shape and calculate the best trace of this spread along a corresponding change in shape of trace, wherein translation function as input, and provides amount various measurements or projection one group and drives order as output by translation function;

    AndAt least use determined best trace to calculate to be used for this group of at least two of spread control elements to drive order, wherein should group driving order the change that comprises spread control assembly mode of operation.
