I have been wanting to update our product line for quite a bit now and one of the first updates is to include a reliable IMU to the 10 HZ GPS. I looked around at a number of different sensors and finally decided on the YEI-3 from Yost Engineering. This sensor is very robust. We were able to preserve the YEI-3 usb interface while still keeping the ability to log data from the GPS and the IMU to the sd card. This allows for the update of the YEI-3 firmware and interface to their 3-Space sensor software. I’ll work on posting some sample data in the next few days!
