Hi

 

There is a customer survey 9-axis fusion for UAV and indoor navigation, but they have no experience before.

They have study other UAV product and list a specification table.

But there are some information that I can not find in datasheet.

Can anybody help provide some information to help fill this table?

I want to design in and win this case.

Really appreciate your help.

Kyle,

Great start on a spec.  I would like to set up a phone call to get a better idea of your opportunity and how Freescale can help.  In the meantime, I'm routing your spreadsheet to my team to see what additional information we can add.

Could you send me your contact details via email to Mike.Stanley@Freescale.com?

Thanks!

Hi Mike

I get a 13 degree sensor output on a 13.7 degree surface. It says there is an ancestor of 0.05 degrees per degree according to this table

Is the accelerometer alignment error in the table per degree ? I hope I'm not wrong
