Tom Jakel commented on Chris Anderson's blog post How do modern open source autopilots compare to aerospace-grade IMUs?
"@Thomas no problem I love these types of discussions. It just so happens that I do what would be a hobby for me as a job. The value in the HG4930 is the sensors AND the calibration. On the HG1120 the value is in the calibration. As far as the value…"

"@Thomas Butler it is no secret that the Honeywell HG4930 uses Honeywell's own bulk micromachined MEMS Inertial Sensors. The HG4930 has noise performance that is 5x better than the ICM20602. The HG4930 also has an RMS gyro bias over temperature…"

"@Rafael Mendy there are quoted values on the HG1120 for full temperature parameters. What we have found is that users confuse them for room temp specs and then discount the IMU based on that. I will say that most of our customers are users who tried…"

"The specifications of so many IMUs that you are quoting are at room temperature only, the Honeywell devices specs are over the full temperature range from -40 to 70 C. There are so many parameters that are calibrated for in the Honeywell…"

"David, ARW is not the end all be all of parameters that matter in an inertial navigation system. It certainly is important but there are many other IMU specs to consider. As always which of the specifications are most important depends on what you…"

"There are so many parameters in IMU calibration that the general drone user may not consider that I'm sure Honeywell does. For instance is the IMU in the Pixhawk calibrated for g sensitive scale factor? That is when the amount of force on the…"
