Let me resurrect
this old thread.
The processing could be done in kinematic mode
(either forward-only or forward+backward combined). That
way, initialization tricks (antenna-swap, fixed-length bar)
as well as ambiguity reinitialization (cycle slips) are less
of an issue.
Then stop-and-go could be implemented forming
weighted averages of the kinematic position coordinates and
precision (3-by-1 vectors and 3-by-3 matrices).
It'd require a time table of occupation
start and end times (and marker name), which could be
obtained simply grepping the rover RINEX observation file to
extract event flags.
If I were to implement this, I'd be easier
for me to do it Octave rather than built into RTKLIB's C
PS: the non-integer epoch seconds can be handled
by teqc, see, e.g.:<http://postal.unavco.org/pipermail/teqc/2012/001310.html>
Thank you for your explanation.
I agree, instead build inside rtklib C code, i am using GNU utils ( grep, awk,sed, octave,... ).
I plan to use 1PPS signal to sync trigger events. ( closed loop ) and will write my own occupation time table logger (gps time sync and epoch count... ).
