The table below lists the different steps you have to go through
before MobileMapper CX can operate in a given DGPS mode,
depending on whether the mode relies on the use of a COM
port, Bluetooth or GPRS.
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.
