Paparazzi uses the Ublox5 GPS modules, which we use with the new ArduPilot expansion board. Basic ArduPilot uses the EM406, which uses the SirfIII chipset. We find the Ublox5 is very accurate, with alt error of no more than a meter. EM406 is less accurate in altitude, but still good enough for our purposes.
