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 Constraints
Enter two observer positions and select bearing–bearing, bearing–distance, or distance–distance.
Inspect Every Candidate
The solver returns every valid ray–ray, ray–circle, and circle–circle intersection rather than silently choosing an ambiguous point.
Calculation Boundary
Results use standard planar geometry. Confirm coordinates, units, and the selected candidate.
Frequently asked questions
Which two constraints can I combine?
The tool supports two bearings, one bearing plus one distance, or two distances using standard planar ray and circle intersections.
Why can triangulation return two targets?
A ray and circle or two circles can intersect at two valid points. Inspect both candidates and use mission context to select one.
What does no valid intersection mean?
The constraints do not meet in the allowed forward direction, are parallel, or describe circles that do not intersect.
