Hot Standby RTK
Rover
Hot Standby RTK is similar to RTK except that two or three
independent sets of corrections are used instead of one. The
receiver will choose the best of the two or three sets of
corrections received in order to improve position availability
and accuracy.
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.
To configure the receiver as a Hot Standby RTK rover, use the
Web Server as follows:
• Go to
Receiver
>
Position
>
Rover Setup
.
• Set
Processing Mode
to
Hot Standby RTK
.
• Specify how the two (or three) sets of corrections are being
forwarded to the receiver by setting
Input Mode
accordingly.
If you choose
Automatic
, the receiver will find by itself
which of its ports are used to acquire the sets of
corrections. If you choose
Manual
, you need to specify
each of the ports used.
