Abstract: An apparatus includes a streamer cable section and a unit. The streamer cable section includes an associated group of seismic sensors. The unit connects to an end of the streamer cable section and includes a steering device, a controller, a network repeater and a router. The steering device is controllable to position the streamer section; the controller gathers seismic data provided by the associated group of seismic sensors and introduces the seismic data to a telemetry network of a streamer; the network repeater repeats a signal communicated along the telemetry network; and the router is disposed between the controller and the telemetry network.

Abstract: A technique includes determining a first difference between a time that a first network element of a seismic acquisition network receives a first frame pulse from a second network element of the seismic acquisition network and a time that the first network element transmits a second frame pulse to the second network element. The technique includes determining a second difference between a time that the second network element receives the second frame pulse and a time that the second network element transmits the first frame pulse. The technique includes determining a transmission delay between the first and second network elements based on the first and second time differences.
