 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... ). 

best regards,
