You can watch it in action here, i got 9 satellites during fly, taking in consideration a 1.3Ghz@1Watt video transmitter very near to it:




The heading and the altitude is not that bad! Soon i will release an easy to solder interface board with EM-406 "like" port.

Needless to say, we'll be supporting this module in all the ArduPilot, ArduPilotMega and ArduIMU code

That sounds great....now if gps's get damaged...they will be half the price to replace

can I just simply solder that wire:

to mediatek gps module and connect it straight to the ardupilot/arduimu ?

Nice Jordi, Ordered just 5 minutes back along with other couple of things, my order number is 3648
@Chris, it is good to hear that you guys are going to add support in ArduPilot (all varients)

Hi Jordi,

How does the GPS interfaces with Ardupilot? Is there a need of a special board between them or just a cable going straight from the GPS to ardupilot? Same as EM406?

tks,
Leonardo

the same module is sell by Flytron for 40$.

good pick jordy.

So if i see this right, it is a cheaper and equal gps to the U-Blox, am I right?
So no real need to go for the U-Blox?

Yes it is very good GPS and we are using it since 2 years(it was 5hz) without any problem.
MTK commandset very simple and easy to switching it for any NMEA pattern or refresh rate.
It's only problem is pinouts, you can remove the "half hole" pins in 1 seconds if you don't use temperature controlled soldering iron.
This is why i'm selling it with Breakout Board after reflow soldering ;)
Breakout boards resolving all cabling problem,including 3Dfix LED and a buffer capacitor for backup the battery for 3 minutes when battery changing.(ofcourse you can change it with a Farad Capacitor for longer backup)

Alternatively, you can use Open pilot GPS with cable ready. Looks like the same cable/connector that Jordi sells along with the shield. I see it is backed up by button battery which is suppose to last years. Neat job.

Jordi, Did you use xbee for telemetry on this flight? If so did the TM drop out also?
