Hot Standby RTK+
Relative RTK
This mode is similar to RTK+Relative RTK (see page 63 )
except that the RTK position is now a “Hot Standby RTK” one
(see also
page 60 ). The combination of these two modes may
be summarized as shown in the diagram below.
On the receiver’s General Status screen, the receiver will
display “FIXED” (with short “FLOAT” transition time) when
computing a position in Hot Standby RTK mode. The
computed position is displayed after pressing
.
When at least one set of corrections is received and used,
is displayed on the General Status screen together with the
age of corrections (see
General Status on page 27 ). The
displayed age of corrections is always that of the corrections
actually used in the position computation.
The components of the vector are visible in the Web Server
(in
Receiver
>
Position
>
Vectors
tab on the right) or by
programming an NMEA VCR or VCT message on one of the
receiver ports (see Web Server’s
I/Os
tab).
To configure the receiver in Hot Standby RTK + Relative RTK,
use the Web Server as follows:
• Make sure the Heading mode is off.
• Go to
Receiver
>
Position
>
Rover Setup
.
• Set
Processing Mode
to
Hot Standby RTK + Relative RTK
.
• Specify how the three sets of corrections are being
forwarded to the receiver by setting
Input Mode
accordingly.
