All use an IMU (Inertial Measurement Unit). * 3DOF category : they only estimate their orientation solely by use of gyroscope + accelerometer (IMU) and magnetometer. They are cheaper. text/html 2022-11-01T01:39:05+00:00 laurentc (laurentc@undisclosed.example.com) https://ufowaves.org/enquetes/simovni2/doku.php?image=simovni2%3Ahmd%3Acalibration%3Atable_alpha_lux.ods&ns=simovni2%3Ahmd%3Acalibration&rev=1667263145&tab_details=history&mediado=diff&do=media text/html 2022-11-01T01:26:45+00:00 laurentc (laurentc@undisclosed.example.com) https://ufowaves.org/enquetes/simovni2/doku.php?image=simovni2%3Ahmd%3Acalibration%3Ahl2_nits.png&ns=simovni2%3Ahmd%3Acalibration&rev=1667262405&tab_details=history&mediado=diff&do=media <img src="https://ufowaves.org/enquetes/simovni2/lib/exe/fetch.php?w=306&h=260&t=1667262405&amp;tok=eaa033&amp;media=simovni2:hmd:calibration:hl2_nits.png" alt="simovni2:hmd:calibration:hl2_nits.png" />
