The Network RTK software option allows
the receiver to generate and receive
RTCM 1000-series messages. The
navigation algorithms are designed to
support single-base correction
configurations. Network adjusted RTK
formats are not currently supported.
RTK WL is a positioning mode that is
necessary for phase ambiguity
resolution. However when this
navigation mode is indicated, it is likely
that the receiver is in a corner case
navigation condition. As such, it is likely
that the end user will not wish to use it
as a valid navigation mode.
If the above conditions are met, then the
receiver will not need to be put into RTK-
WL mode.
RTK Extend is a purchased software
option that uses StarFire to provide
continuous RTK positioning during non-
reception of RTK corrections. When a
StarFire-enabled receiver with RTK
Extend falls out of RTK mode, the
system automatically transitions to RTK
Extend mode. Positioning is maintained
because of the close correlation in
phase measurement corrections
between RTK and StarFire.
Depending on how long the RTK base station
has been running and is StarFire-fixed, the
duration of RTK Extend is limited to:
