RTK Implementation
If the increase is only temporary, then you should not care too
much about the data link as long as the rover continues to
provide “fixed” positions.
But if the age of corrections keeps on increasing, then the
problem is more serious as it can only result in a rover losing
the “fixed” status for all the positions it delivers. In this case,
you should figure out why the data link fails and take the
necessary steps to bring it back to work.
So the recommendation is to constantly keep an eye on the
age of corrections as you progress in your field operations.
In some of the available Spectra Precision receivers, you can
set a parameter, called “maximum age of corrections”
defining an upper limit for the age of corrections. If for any
reason the age of corrections reaches this limit, a warning
message will alert you.
