To understand more about IMUs and IRS, I have chosen the Honeywell 6DF-1N6-C2-HWL Inertial Measurement Unit as an example:
- I don't see any mention of the output of the IMU in the linked datasheet - have I got it wrong? And how to convert the output into meaningful data? How do I convert raw accelerometer data into Speed in knots, for example? Is there a specific formula to calculate the speed (velocity might be apt) while also taking into account the movements in other directions as well?
- Is the raw data from this specific IMU accurate enough for use in a GA aircraft / Light Sport Aircraft?
- Am I right in saying that this IMU doesn't need Pitot / Static sources?
While most details might be about this specific IMU, please feel free to also give answers that apply to all IMUs as a whole.
EDIT: I do not want any positional data. I prefer an AHRS with Airspeed and Altitude sensing capabilities.
