Tracking Overview
The Ditch Witch
®
TK Series Guidance
System is designed to function with
horizontal directional drilling units. The
system is composed of three components:
beacon transmitter, tracking unit, and
display unit.
TX, TXH, TXQ, and TXQG beacons
transmit roll angle, beacon temperature, beacon battery status, and pitch information and perform best in
Ditch Witch approved tool housings.
TK trackers detect beacon transmission and relay data to TD displays onboard the drilling unit. The
tracking data can be logged and transferred to tracking software.
TX series beacons emit a dipole magnetic field
that can be used multiple ways to determine
beacon position. The beacon is always located at
peak signal strength between two null points (also
known as ghost signals). The peak signal strength
region (B) is located directly over the beacon. The
two null point regions (A) are located in front of
and behind the beacon.
If the TK tracker is in one of the null point regions,
the null point icon (A) will be displayed with fore/
aft and/or left/right arrow showing the direction to
move the tracker to the null point.
If the tracker is in the peak signal strength region,
the beacon icon (B) will be displayed as well as a
fore/aft arrow to guide the tracker over the plane
perpendicular to the beacon axis.
When the beacon has been correctly located, the
depth reading is displayed.
