Systemic error can be dealt with by bisecting each angle formed by intersecting position lines.
If a triangle, and azimuths with a spread of less than 180 degrees, then the fix will be outside the triangle. The probability is 100%.
With an azimuth spread greater than 180 degrees, then the fix will be at the centre of the triangle. The probability is, again, 100%.
