Rover Acquiring
Data Stream From
a Base
The rover needs to be configured as in Direct IP mode via
Ethernet (see Direct IP Via Ethernet on page 22).
Rover Operating in
Flying RTK Mode
• Follow the steps described in section General Parameters
on page 16. At the top of the Rover setup page, select
Ambiguity Fixing=0 in the Rover pane.
• Choose the method used to let the rover acquire RTK
corrections.
With ProFlex 800, if several rovers in Flying RTK mode are
assumed to use the same source of RTK corrections, the
internal modem can be used individually in each rover (in
GPRS mode). The source of corrections will typically be a
ProFlex 800 base using the embedded NTRIP caster.
Another possible solution is to insert the Ashtech RTDS
software in the communication path so that the
corrections can be distributed to all the rovers.
Rover Operating in
Hot Standby RTK
Hot Standby RTK is the process of making available a second
RTK position solution in the background. Should the primary
RTK solution stop being delivered by the receiver for some
reason, then the second RTK solution would be provided
instead, until the primary RTK solution is back again and
valid.
If you wish to make available this background solution, then
enable the
Hot Standby RTK option at bottom of the page. You
are then asked to specify which port will route the differential
corrections used to compute that solution (you should use a
source of differential corrections different from the one used
for the primary solution; make sure this source of corrections
will be delivered on the specified port).
Defining Output
Messages
Depending on your application, you will have to define
different types of data output messages as well as the way
they are delivered to outside equipment (typically through a
serial port for a rover).
