How to Work with JNSGyro-2T
The command
%HD_USELEN%set,hd/uselen,on
says the rover to use the
known distance between antennas.
If this set to off:
%HD_USELEN%set,hd/uselen,off
the heading engine will
estimate this value itself and will keep it filtered; in this case the command
%HD_LEN%set,hd/len/,<length>
has no effect.
This setup works at 5Hz. There is an ability to work at 10Hz.
There is a possibility to use the three antennas installation running the Mov-
ing base differentially corrected from the
Base
(
B
)
BASE(port c)->(port c)MOVING_BASE(port b)->(port b)ROVER
If we suppose, that the
Base
sends CMR correction to the
Moving base
, the
configuration scripts are:
1. For base:
set,base/mode/,off
set,rover/mode/,off
set,raw/corr/ca/code,normal
set,raw/corr/ca/carrier,normal
set,raw/clp/loops,off
set,pos/elm,5
set,pos/mode/cur,sp
dm,dev/ser/cset,raw/msint,200
set,pos/msint,200
em,/dev/ser/c,cmr{/10:0.2,/0:0.2,/1:0.2}
set,dev/ser/c/rate,9600
set,dev/ser/c/rtscts,off
set,ref/pos//geo,{W84,N55d42.8555m0s,E37d35.5743m0s,193.6} #
for example
2. For moving base:
set,rover/mode/,off
set,base/mode/,off
