To choose and enable a DGPS mode, use the DGPS Configu-
ration utility as explained in detail in the continuation of this
chapter.
Once a DGPS mode is used, any accidental disruption in the
flow of incoming data packets will trigger a warning message
of the type "No differential corrections received over xx sec! Cor-
rection age limit = xx sec". This will happen after a time tied to
the value you will have assigned to the Real Time Correction Age
Limit parameter. When this warning message appears, Mo-
bileMapper CX will automatically switch to Autonomous GPS
mode.
