I am using OpenLog Artemis with the SAM-M8Q and I need help interpreting the numbers it records. The accelerator values are obviously in milli-g's, the Lat and Long are degrees times 10^7, and GPS heading appears to be degrees * 100,000. But I can't figure out the units and scale factor for the magnetometer, gyro, GPS altitude, GPS ground speed, and GPS pDOP. I couldn't find anything in the docs on the site.

Thanks,
Matt

Hi Matt,
I'll create a markdown document that summarizes all of the units. (You're not the only person to have asked for this! )
I should be able to get this done tomorrow.
Best wishes,
Paul

Hi Matt,
I've added the sensor units here:

Please let me know if you spot any errors!
Best wishes,

Hey, thanks for posting the units. After I posted that "acceleration is obviously milli-gs", I realized I might be wrong -- it could be m/s^2 * 100. Just want to confirm that you didn't just go by what I said

Also, I thought PDOP was dimensionless, as it is a ratio.

Thanks,
Matt

Hi Matt,
Wow. You're right about DOP being dimensionless! I need to change that.
Thanks!
Paul
