Earl, can you explain a bit more what this is? Is it something we should incorporate in the main ArduIMU code?
Comment by Earl on August 22, 2010 at 7:35pm
Well Chris, If you want to use the MTK GPS instead of the uBlox, this should do it !
I was kind of forced to do the code because my uBlox quit and I only had the MKS GPS unit.
It is choice 4 in the code so it is an addition in the IMUcode that a few my like.
Yes, I would suggest putting it in the SVN when more people check it out.

did the MKS GPS come pre-programed to output in binary?

Thats a good question. I don't remember programming it to binary. I got mine from the DIY store so I think it was pre programmed to binary.
To set it to binary is not too hard. I will check how.

Here is the string to send to the GPS to enable the binary mode
This sets the baud rate to 38400
Here is a lot more info.

Earl, I loaded the code up on the ArduIMU, hooked up the MTK GPS, and connected ArduPilot. The altitude reported on the ArduGCS appears to be 1/2 of actual. GE shows 659 Feet, my
EM-406 showed 200 Meters.
MTK shows 100 Meters.

There seems to be an error in Earls MTK Lib. I'm trying to do a quick update to the SVN.
