an incorrectly configured ESC telemetry source can lead to a notch running at very low frequencies. A simple example is a lua script like this: function update() esc_telem:update_rpm(12, 0, 0) return update, 10 end return update() where motor 12 is unused. with that script in place we get a 1.0078 Hz filter which leads to massive phase lag and a crashed aircraft this is a safety protection. We should also try to find out why the INS_HNTCH_FREQ lower limit is not working
these undocumented bits in register 0x4d control the "adaptive full scale range" mode of the ICM42688. The feature is enabled by default but has a bug where it gives "stuck" gyro values for short periods (between 1ms and 2ms):, leading to a significant gyro bias at longer time scales, enough to in some cases cause a vehicle to crash if it is unable to switch to an alternative IMU this fixes ArduPilot#25025
this allows a lot more drivers to use the GPS_DRV_OPTION but to use ellisoid height. Particularly useful for DroneCAN GPS modules using ellisoid height instead of AMSL is useful in some specialised application
this caused lots of lost packets
