[teqc] Trimble & Leica PPK (Mixed Track) data translation.

Hi Lou

I'm not sure if I'm attempting something that is outside the intended 
scope of teqc or am just missing something vital.

I am using the latest release version of teqc (2010Mar17) and am 
attempting to translate PPK data from both a Trimble R8 and a Leica 
ATX1230.  Both the Trimble (*.dat) and Leica (*.m00) files contain mixed 
track data.  That is, continuous sessions containing both kinematic and 
static sections.

When translating either Trimble dat or Leica mdb files, should teqc be 
able to produce mixed track RINEX output correctly tagged with event flags 
2 and 3 as appropriate?

When I attempt to translate the Trimble data using teqc without any 
options specified, the translation runs without any significant notices or 
errors and the following is an extract of the output produced.

Teqc therefore appears to be correctly identifying the start/end of each 
static/kinematic section but is only tagging them with additional header 
info (event flag 4) and a comment noting the change but is not inserting 
the correct event flag to identify the section as kinematic or static 
(event flags 2 or 3).  The following is an extract of the type of output I 
am trying to achieve (as produced by Trimble's TGO software which I only 
have access to via a colleague).

Attempting to translate the Leica data appears to be slightly more 
problematic than for the Trimble data.  When I attempt to translate the 
Leica file (without specifying any teqc options) the resulting output does 
not contain any tags or comments to indicate the start or end of any 
kinematic or static sections.  The output appears as if it were a single 
static occupation.

Is teqc capable of producing what I am wanting or do I need to use Trimble 
and Leica proprietary software for this type of translation?

Thanks for your time.

Best regards
Neville
