The main thing they're pushing is power consumption. The accuracy & speed isn't improving. 5Hz 1m deadband is still standard. Accuracy & speed would take raw navigation data for use with a free RTK library or dual frequency support & that isn't going to happen. Or were you recommending us purchase the uBlox 6?

I have palyed with one of these in the lab - the performance is almost identical to the ones we use now as far as channels, tracking, speed of acquisition, etc. - but the power consumption is somewhat improved. The smaller units may be of some interest due to the physical size reduction, but even that has its drawbacks.

Hi,
Can anyone confirm the max update rate of the 6 with 5HZ?
Although the specs of the Ublox 5 (LEA 5H) stated 5HZ, due to several reason it was only about 2HZ.
Check out: http://www.u-blox.com/images/downloads/Product_Docs/u-blox5_Fw6.00_...(GPS.G5-SW-09022).pdf
If you doubt it can only do 2 HZ.

Thanks,

Peter

What about this one Amy 5M which is claimed to be smallest with better power handling.

Here is the reply to my email.
"Thank you for your interest in u-blox GPS products. The LEA-6H will be available in engineering samples in early 1Q10 with production ramping in 2Q10. I have attached an overview but you need not delay your development. The LEA-5H is the current version and has the same pinout and interface as the 6H. "

The 'better accuracy/faster speed' I mentioned had more to do with the additional correlators (2 mil vs. 1mil on the u-blox 5).

I've also attached the data sheet. It mentions another model (non-programmable) which supports precision timing and raw data (though we don't really need that stuff).

It also has a USB output which could be interesting (if you're connected to a laptop or other).

We have just been putting these on our PCB's. Too early for any test results yet.

Note: My reply was for the AMY 5M not the LEA-6H
