Are you guys ever gonna release a product with the proprietary sensor fusion you talk about in the wiki? #33

The one you talk about in here: https://github.com/kriswiner/EM7180_SENtral_sensor_hub/wiki/K.-Limits-of-Absolute-Heading-Accuracy-Using-Inexpensive-MEMS-Sensors

I'm working on a robotics project/application that needs really good heading accuracy (<=1deg) and responsiveness (>250Hz) at moderately high velocities (10m/s). Right now it seems the EM7180 USFS is the closest product (that doesnt cost 1000s of dollars), but apparently your algorithm is even better.

Do you have plans to release a product/module with this? Or could I talk to you about privately producing a few modules for me.

Thank you

Also, do you have experience with the more expensive IMU AHRS solutions like the Redshift UM7, Fairchild FMT1030, Xsens Mti etc? Any products in the 100-200usd range that provide good performance out of the box?

From our testing and that reported by others no available solution in the < $10K category does better than our inexpensive USFS solution.

We are working to build a similar device that uses our proprietary calibration and fusion algorithms, but we are a few months away from general availability. You can keep track of our progress here https://hackaday.io/project/160283-max32660-motion-co-processor.

In the meantime, I would recommend that you try the EM7180 + ST https://www.tindie.com/products/onehorse/ultimate-sensor-fusion-solution-lsm6dsm--lis2md/ sensors solution. If you were to buy five, say, then after proper calibration each would produce < 2 degree rms heading accuracy and two or three of them would produce ~ 1 degree rms heading accuracy. At least this way you could do basic testing to determine whether 1 degree heading accuraxy is sufficient in your application.
