Model 3510LR / VBS or VRC Mode Setup
In this mode a composite set of RTCM corrections is computed from the GPS
network data sent over the link. The following information is required to compute
these corrections; time (supplied via the link), GPS almanac data (supplied via the
link), and receiver location either entered via Toolkit or from an external GPS
receiver interfaced via the Data port.
When the unit is first supplied, or not
used for a long period of time, or moved a large distance between use it
may take up to 40 minutes to start outputting RTCM corrections.
•
If the 3510LR is operating in VBS/VRC mode the RTCM data will appear on
the Data port, this port will need to be set up to match the requirements of
your GPS receiver RTCM IN/NMEA out port, Configure Ports – Data Port
menu item to set these.
•
For the VBS or VRC operation the 3510LR needs to be supplied with a
position for the area of operation, this can be supplied automatically from an
external GPS receiver or manually via Toolkit. If using an external GPS input
the GPS receiver must be set up to output $xxGGA NMEA format position
telegrams in addition to any other required message types. The NMEA data
is input via the Data port, therefore the port parameters must match those set
for the RTCM data output, see the set up details for this port above.
