From the devs that have been fortunate enough to get one of the prototypes, this gps is definitely more accurate than the media tek.

When it comes to hitching it up to an APM2, it's super easy if you bought an APM2 with no built-in GPS.  In this case, it'll just plug into the little white connector on the front of the APM2.

If you bought an APM2 with the built in gps though, you'll need to disable the Mediatek GPS somehow because otherwise both GPSs will be fighting over the same serial port.  I don't think there are any instructions on the wiki yet but I think it's going to involve cutting some traces on the daughter board.

You can drop a resister between two pins on the daughterboard, and use an external GPS....

finally!

It's not obvious from the photo, but this is about 4x bigger patch/board than the MTEK. 

Three reasons why I've just bought one:

1) It has ridiculously good accuracy (I saw it proven at Sparkfun AVC)

2) It has a bigger antenna (in antennas... size matters!)

3) It can be placed on a mount far from the APM, the ESCs and other sources of noise and get a clear view of the sky

Can't wait to get it!

Just ordered one. Only 199 left now! LOL

Is this the OpenPilot footprint?

3D Robotics Comment by Sam Kelly on July 3, 2012 at 5:32pm

I haven't seen the latest OpenPilot GPS boards, so this probably doesn't match their size or mounting holes.

Can anyone give more specs on this?  Update rate, accuracy, and signal delay??

3D Robotics Comment by Sam Kelly on July 3, 2012 at 6:02pm

Hi JesseJay, that is in the LEA-6 data sheet: http://www.u-blox.com/images/downloads/Product_Docs/LEA-6_DataSheet...

This is the module I used to finish the Sparkfun AVC course with ArduRover. My car can't go very fast, so I couldn't win, but this GPS was my secret weapon in terms of accuracy. On the ground, where multipath distortion is a problem with GPS, this combination of next-gen chipset and bigger antenna blew the MTK away.
