Ah Michele, I didn't realize you were on the list, I've been
following your blog periodically. I guess I didn't realize I was
seeing your name in two different places... how odd, I've been
reading your answers to my questions!<br>

I have and use regularly NEO-6P though, which has PPP and
carrier phase output.<br>
The only drawback of NEO6P is that it uses a simple crystal
instead of a TCXO so the Doppler values will be generally quite
high.<br>
That does not impact the carrier phase output quality however:
in zero baseline mode -in very good visibility conditions-
"static" gives me just a few mm variance and zero mean.<br>
<br>
As I mentioned ealier in PPP mode it does not make sense to talk
about rover and base as it is a _standalone_ positioning mode.<br>
<br>
The hacked version of RTKLIB for NV08C is actually here:<br>

and it's currently being updated according to the recently
released document here:<br>

<div class="moz-cite-prefix">Well, now, I've seen the LEA-6P
units are standalone PPP. But RTKLib has kinematic mode which
seems to use 2 units and this "differential".<br>
<br>
I did download the patched version of rtknavi that has a PPP
fix.<br>
I discovered that the PPP "Static" for determining the base
station location was pretty stable- however, it determines the
location for the "rover" only, so I just swapped the rover and
base port #'s to determine the static base location.<br>
<br>
When I selected PPP Kinematic, the fix jumps several meters
back and forth rapidly, but never seemed to stabilize much,
and the noise wasn't really centered on the true location
either.<br>
<br>
I ordered the NV08C-CSM units, BTW. These new kids on the
block are GPS AND GLONASS, Galileo, Compass, and <span

standard accuracy, and a few months back the mfg released
firmware to expose the RAW pseudorange data. Michele Bavaro
thinks highly of them, and there's a hacked version of RTKLib
for them: <br>

The first is differential, the second standalone. <br>
