Neo 7 seems good, but I want to know a litter bit more.
I'm just trying to find a way to have a cm level precision outdoor position method, a previous post about RTK-GPS in the kiskstarter looks great but it's a bit expensive.

Subject: [Paparazzi-devel] NEO7 gps test
Just to let all know that i just tested this gps
and it works really really good.
It's sensitivity is excellent and it locks in a second where all the
others i have need at least 30 seconds or don't lock at all in the same
I use the ubx center module because despite it's description IT DOES NOT
HAVE AN EEPROM like the hobbykings still excellent NEO6 GPS, only a
small battery or capacitor and it will loose it's settings after 15-30
I also don't know how resistant it is with interference from video
transmitters but it does have an active antenna with a SAW filter and it
does not get affected when on top of the stm32f4 cpu of the discovery
board i used for testing.
Maybe someone might know if we can benefit from the 10Hz refresh rate
NEO7 has and if ubx center needs to be updated to set the refresh rate also.
