Receiver Description
Enabling a firmware option purchased separately from the
system relies on the use of the $PASHS,OPTION serial
command. For more information on how to enable an option,
refer to OPTION: Receiver Firmware Options on page 414.
Understanding RTK, RTK3, RTK2 and STA firmware options.
Because these options have some intertwined properties, you
usually don’t need to have them all activated in your receiver:
• To get a full-featured RTK base, you just have to choose
one of the following options:
– RTK [K],
– STA [N],
– or RTK3 [L], the notion of limited RTK applying only to
a rover, not to a base.
You’ll get the same level of base operation whatever the
option you choose.
• To operate an RTK rover, you just need to choose one of
the following options:
– RTK [K], full RTK range (unlimited),
– or RTK3 [L], RTK operation limited to baselines up to
3 km (pre-installed option).
Your choice will depend on the baseline length you wish
to cover in RTK. Note that option [K] “includes” option [L]
in the sense that option [K] also allows the rover to operate
in RTK for baselines less than 3 km.
• RTK2 (pre-installed) is equivalent to RTK except that it
does not support RTCM and CMR/CMR+.
