freescale 9-axis sensor fusion specification

Question asked by Kyle Yang on Jul 15, 2015



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.
