I am not aware of any uBlox LEA-6P?
I have and use regularly NEO-6P though, which has PPP and carrier phase
output.
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.
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.
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.
The hacked version of RTKLIB for NV08C is actually here:
http://www.onetalent-gnss.com/ideas/usb-hw-receivers/denga10
and it's currently being updated according to the recently released
document here:
http://www.nvs-gnss.com/support/documentation/item/32-binr-protocol-specification.html
for LLI and SBAS support.
Cheers,
Michele

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".
I did download the patched version of rtknavi that has a PPP fix.
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.
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.
I ordered the NV08C-CSM units, BTW. These new kids on the block are
GPS AND GLONASS, Galileo, Compass, and SBAS, 2.5m 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:

So, this should be fun!

There is a huge difference actually.
The first is differential, the second standalone.

Could someone explain the difference between simple Kinematic and
PPP Kinematic in RTKLib?
