GSA - GPS DOP and active satellites. This sentence provides details on the nature of the
fix. It includes the numbers of the satellites being used in the current solution and
the DOP. DOP (dilution of precision) is an indication of the effect of satellite geometry
on the accuracy of the fix. It is a unitless number where smaller is better. For 3D fixes
using 4 satellites a 1.0 would be considered to be a perfect number. For overdetermined
solutions it is possible to see numbers below 1.0. There are differences in the way the
PRN's are presented which can effect the ability of some programs to display this data.
For example, in the example shown below there are 5 satellites in the solution and
the null fields are scattered indicating that the almanac would show satellites in
the null positions that are not being used as part of this solution. Other receivers
might output all of the satellites used at the beginning of the sentence with the
null field all stacked up at the end. This difference accounts for some satellite
display programs not always being able to display the satellites being tracked.
