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!

Chris: Thanks for your information! I use the APM 1 (v. 2.049) with an extended kit (second platform) from http://www.snelflight.co.uk/QuadPod.htm as a very small quad "Ardupilot + QuadPod) for experiences! Other people are perhaps also interested in as a second version of the "Tyni Quad") also for indoor use. APM v. 2.049 is not yet compatible with the ublox GPS?
Hans: Yes. No configuration needed if you're using the latest ArduPlane/ArduCopter code. It will be autodetected and set up automatically.
Is the ublox GPS also compatible with the APM 1 in place of the MTK GPS? Is there a need for a special configuration action?
I think that 3m position accuracy is good first indicator of how good the GPS is..of course it'll tell you how far the position the GPS is reporting is from it's actual position..but more important to the performance of loiter is the accuracy of speed information. Again, sorry, it's a bit anecdotal and lacking in hard data to back it up but this seems much better on the ublox.
@Ronald,
I think that Chris Anderson stated that he was subjectively getting around 30cm accuracy while running a course with his rover over a 25 minute period. The 30cm accuracy was the variance of the rover outside of the intended course.

If you look at the datasheets for either the MTK 3329 or this Ublox LEA-6 they list position accuracy about the same; less that 3meters. So, for those of you that have used both: Can you put it in simpler terms? Just how much more accurate is this Ublox? As an example...I've got a GPS from Parallax and I'm lucky if it's accuracy is (about) +/- 60 feet (it's an older unit)... Is this new Ublox really as the datasheet says, down to about 10-11 feet?
Does anyone know or has tested if the new 3DR GPS LEA-6 will work with the Remzibi OSD sold in the 3DR store? I see this OSD is listed as not supported with APM2 so I am thinking no on my GPS question.
Jonathan, all my videos of beta/alpha/release 2.6 are created using U-Blox GPS prototype (LEA-6M, not 6H):

There are a bunch here, but here's one.
Thanks, Chris. Link? Tried searching but I just found a promo video. Thanks
