Dear Timo,
This is what I wrote from you code:
1)Sets NMEA OFF and only UBX on
2)Enable-raw
3)raw-rate-monitor
*import struct
import calendar
import os
import gobject
import logging
import sys
import socket
import time
loop = gobject.MainLoop()
def callback(ty, packet):
print(callback %s

Hi,
in Finhack 2010 I gave a presentation on how I
1) modified the freerunner GPS firmware to obtain raw pseudorange and
carrier phase measurements,
2) used two openmoko freerunners (base at a known location and
rover that is moving around) with external antennas to capture this
data and

So if I understand it correctly all you need is two freerunners for RTK-GPS
to work? Does one need to have a DGPS subscription?
