Abstract: A drill string communication system is described. An uphole transceiver can couple a signal onto the drill string at a power that is always greater that a selectable power for a downhole signal. Communication from a drill rig to an inground tool can be re-initiated using a maximum uphole transmit power of an uphole transceiver. A procedure can establish a new set of transmission parameters for a drill string signal to establish communication between the drill rig and the inground tool. The system can include a walkover locator that receives an active/inactive status-controlled electromagnetic locating signal. Responsive to a locating signal degradation, a reconfiguration command can modify the locating signal. The uphole transceiver and a downhole transceiver can automatically modify at least one parameter of a downhole signal. An uphole receiver can apply a compensation response to a transferred signal to compensate for a drill string channel transfer function.

Abstract: A transmitter is carried proximate to an inground tool for sensing a plurality of operational parameters relating to the inground tool. The transmitter customizes a data signal to characterize one or more of the operational parameters for transmission from the inground tool based on the operational status of the inground tool. A receiver receives the data signal and recovers the operational parameters. Advanced data protocols are described. Pitch averaging and enhancement of dynamic pitch range for accelerometer readings are described based on monitoring mechanical shock and vibration of the inground tool.

Abstract: A portable device and associated method are described for use with a system in which a locating signal is transmitted from within the ground during an operational procedure. The locating signal includes a transmission frequency that is selectable from a group of discrete transmission frequencies in a frequency range and the region includes electromagnetic noise that can vary. The portable device includes a receiver having a bandwidth that includes the transmission frequency range and is operable for measuring the electromagnetic noise in the transmission frequency range to establish a frequency content of the electromagnetic noise for use in selecting one of the discrete transmission frequencies that is subsequently transmitted as the locating signal during the operational procedure. The locating signal can be transmitted from a boring tool, a pullback arrangement or an inground cable. A predicted maximum operational depth for a transmitter can be determined prior to the operational procedure.

Abstract: A portable device is described for use with a system in which a transmitter signal is transmitted by a transmitter from within the ground during an operational procedure. The portable device is configured for measuring electromagnetic noise. An extension leg is removably attachable to the portable device and supports a measurement wheel at a distal end such that the electromagnetic noise is measured on a measurement path along which the measurement wheel is rolled for use in selecting a transmission frequency for the transmitter signal.

Abstract: A portable device is described for use with a system in which a transmitter signal is transmitted by a transmitter from within the ground during an operational procedure. The transmitter signal includes a transmission frequency that is selectable as one of a group of discrete transmission frequencies and the region includes electromagnetic noise that varies. The portable device includes a receiver that measures noise continuously along a path, with the transmitter inactive, to generate one or more indications for each discrete frequency at each location and continuously update the one or more indications for use in selecting one of the discrete frequencies as a selected transmission frequency to avoid local interference.
