Geometric Dilution of Precision
</dt>
(abbr GDOP). As applied to a trajectory
measuring system, the increase in error of calculated space position which
is caused by the location of the measured position relative to the system.

This is an increase which is caused solely by the geometry of the
problem and assumes that all basic measurements maintain a constant accuracy.
