The instrument source
The instrument source describes where the coordinate triplet was measured or entered. The

The coordinate quality
Description
The Coordinate Quality is:
•
computed on the rover for code solutions and phase fixed solutions.
•
an indicator for the quality of the observations.
•
an indicator for the current satellite constellation.
•
an indicator for different environmental conditions.
•
derived such that there is at least a two third probability that the computed position
deviates from the true position by less than the CQ value.
•
different from the standard deviation.
CQ versus standard deviation
The standard deviation as CQ would often be too optimistic. This is why the computation of
the CQ in GPS900 is not simply based on the basic standard deviation algorithms.
For the standard deviation, there is, statistically, a 39.3 % probability in 2D that the
computed position deviates from the true position by less than the standard deviation. This
is not enough for a reliable quality indicator.
