Boring tool tracking/guiding system and method with unconstrained target location geometry
First Claim
1. In a system for tracking a boring tool that is moved by a drill string within an underground region where movement of the boring tool is characterized by certain orientation parameters including pitch and yaw and which system is configured at least for establishing the pitch and yaw orientation of the boring tool, a method comprising the steps of:
- determining a first pitch orientation and a first yaw orientation of the boring tool at a first position of the boring tool;
moving the boring tool to a second position;
determining a second pitch orientation and a second yaw orientation of the boring tool at the second position and a distance between the first and second positions; and
using the first and second pitch values, the first and second yaw values and the distance between the first and second positions at least to determine a curvature of said drill string.

Abstract
An assembly and method for use in a system for tracking a boring tool that is moved by a drill string within an underground region where movement of the boring tool is characterized by certain orientation parameters including pitch and yaw includes a first arrangement for determining a first pitch orientation and a first yaw orientation of the boring tool at a first position of the boring tool and for determining a second pitch orientation and a second yaw orientation of the boring tool after moving the boring tool to a second position. A second arrangement establishes a distance between the first and second positions. A third arrangement uses the first and second pitch values, the first and second yaw values and the distance the between the first and second positions at least to determine a curvature of the drill string.
