QUICK ANSWER
Enter coordinates and bearings for two spotters plus your NEST position. Use the intersection only if both ray distances are positive and the lines are not nearly parallel.
Operator briefing
The tool solves two forward rays and then calculates a separate NEST-to-target line. It warns about parallel lines and intersections that fall behind a spotter, two situations a basic infinite-line formula can hide.
Use the procedure below as a decision sequence, not as a substitute for the live mission order. Random coordinates, balance values, and mod compatibility can change; stable facts and version-sensitive evidence are labelled separately.
Triangulation solution
Convert map units to real range before using a firing calculator. Check the plotted point visually.
Field procedure
- 01
Choose one consistent map coordinate system; use east/right as X and north/up as Y.
- 02
Enter each spotter’s coordinates and clockwise bearing from north.
- 03
Enter the current NEST coordinates, especially after an Emergency Move.
- 04
Calculate and inspect geometry warnings before accepting the intersection.
- 05
Transfer the final NEST bearing and range into a new firing solution.
Checks before you commit
- Nearly parallel bearings magnify small map-reading errors.
- A mathematically valid infinite-line intersection can still lie behind a spotter; this tool checks ray direction.
- Scale the output range to the map’s real units before passing it to the ballistic calculator.
When the live game conflicts with this page, keep the live observation, game build, and source date. That evidence becomes the next revision instead of being silently forced into an old answer.
