Applications
You can delete poor observations and recalculate if necessary. You can also select the
BS point.
If the angle between known point 1 and known point 2 (measured from the station point) is extremely acute or
extremely oblique, the resulting solution will be less reliable geometrically. For geometric reliability, select
known point locations (or station point locations) that are widely spaced.
