Hi Ben,
i found the following: in the data sheet:
Note: GLENS and GPS signals cannot be received and tracked
simultaneously by u-blox 7 modules.
NV08C-CSM

This receiver uses two MAX2769 the Piksi only one.
The NV08C-CSM receiver performs also pseudo ranges and phase
information for RTK.
Normally the gps antenna for the RTK base station has to avoid
reflections an use a metal plane with >20cm diameter.
I am surprised that only a small module antenna of the Piksi can
perform phase measurements .
How is this physically possible?
In 2010 we made experiments with the ublox samls module and RTK.
We had errors in the 50cm range.

BTW, u-blox 7 can do GLONASS, but its not clear if it can do it at the
same time as GPS.

Hi Ben,
GLONASS+GPS are incompatible because they use different frequencies and
modulators.
The NV08C-CSM has tow different frond ends.
Aha! Do you know where one can get hold of them?
GPS+GALILEO are compatible. But we have to wait a few years for a working
GALILEO system.
The satellites are manufactured in Bremen.

Hi Christophe,
the RTK- project from Japan runs with the beagle board and low cost ublox
receivers:
http://gpspp.sakura.ne.jp/paper2005/isgps_2009_rtklib_revA.pdf
A low cost solution is to combine the raspberry pi (45Euro) with Navilog NL
507TTL (13 Euro) for a DGPS base station and upload the correction data
with the paparazzi link to the UAV (rover).

To get better position data to use a multi norm receiver like the
NV08C-CSM ( http://www.nvs-gnss.com/products/receivers.html
GLONASS+GPS+GALILEO+SBAS ) is also a excellent way . My smart phone has
also a muti norm receiver and uses up to 21 satellites for position
estimation.

According to the chip docs u-blox 6 has 50 channels. is this different
from multi-norm?

is it available yet?
en what is the status of the RTK software?

Happy New Year,
The Piksi RTK GPS team mentioned Paparazzi integration in a prior campaign
update, are any devs here working on this?
Thanks for your time.
Best regards
Richard
