Geophysical exploration utilizing telemetered seismic data and airborne receivers

摘要

A method of seismic data gathering employing a plurality of data acquisition units, each having a detector and a radio transmitter; a plurality of sources; and a control station equipped with a plurality of receivers, one for receiving on a respective different frequency a transmission from each of the data unit transmitters operated in conjunction with the activation of the first source and then in conjunction with the activation of the second source and so on in roll-along fashion. The control station is preferably airborne and the data acquisition units each include a receiver for receiving command control signals and, in one embodiment, a recorder for retransmission purposes upon receipt of a proper command request signal.
