A cableless seismic acquisition system that is configured to resolve the locations of a plurality of cableless seismic acquisition units (e.g., up to 1,000,000 or more) of the system at sub-meter levels of accuracy (e.g., less than 10 cm, less than 5 cm, etc.) free of many of the limitations of existing manners of determining cableless unit locations in seismic acquisition systems. While accurately determining cableless unit locations for use in mapping underground structures of interest, the disclosed cableless seismic acquisition system also limits power demands of and ultimately power consumption by the cableless units to extend serviceable deployment time of the cableless acquisition system.
