IRON NEST Triangulation Calculator
Plot two bearings, a bearing and distance, or two distances. The calculator finds every valid intersection and reports target bearing and range.
Choose Two Triangulation Constraints
Enter two observer positions and choose bearing–bearing, bearing–distance, or distance–distance mode. The solver supports ray–ray, ray–circle, and circle–circle intersections.
How to Read the Plot
Station A and Station B remain tied to their own coordinates and constraints. A bearing creates a forward ray; a distance creates a circle. A valid target must satisfy both constraints at the same point.
How Target Candidates Are Handled
The plotter returns every valid candidate. Parallel rays, intersections behind an observer, non-intersecting circles, and ambiguous two-point results are identified instead of silently invented.
Calculation Boundary
Results use standard planar geometry from your inputs. Confirm coordinates, units, and the selected candidate before using the result.
