New 3D Robotics product: u-blox LEA-6H GPS

Hi everyone! I'm very happy to announce our new u-blox based GPS board. The development teams and 3D Robotics have been working on this GPS unit for some time, and we have seen very good results on ArduPlane, ArduCopter and ArduRover. The Sparkfun AVC and the Quadcopter Rodeo were excellent opportunities to observe this GPS in action, and it helped Team Overhead win first place at AVC.

The device is pretty straight-forward. It has active circuitry for the ceramic patch antenna, rechargeable backup battery for warm starts, and I2C EEPROM for configuration storage. The units will ship pre-configured for ArduPilot Mega use, and the configuration file is available in the repository if needed.

Features and Specifications:

  • ublox LEA-6H module
  • 5Hz max. update rate, configured for 4Hz for APM
  • 25 x 25 x 4 mm ceramic patch antenna
  • LNA and SAW filter
  • rechargeable 3V lithium backup battery
  • low noise 3.3V regulator
  • I2C EEPROM for configuration storage
  • power and fix indicator LEDs
  • ArduPilot Mega compatible 6-pin JST connector
  • exposed RX, TX, 5V and GND pads
  • 38 x 38 x 8.5 mm total size
  • 16.8 g weight

It's on sale now, price is $75.99 USD. It starts shipping on Monday, July 9th.

Design files and links to the board's main component data sheets can be found in the product listing.

We look forward to hearing your feedback!

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....

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?

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??

Hi JesseJay, that is in the LEA-6 data sheet:

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.
