| Mar 24, 2014 at 13:24 | comment | added | fgrieu | Ah, I stand corrected, thanks all. My previous exposure to IMU was in a non-aviation context (robots!) where position is thought for timeframes in minutes. I found this article which confirms the 0.6 nautical miles per hour. | |

| Mar 24, 2014 at 12:40 | comment | added | DeltaLima♦ | @fgrieu Due to the Schuler tuning, the error is only growing quadratically during the first 10 minutes or so. The errors are oscillating with a period of 84 minutes. | |
| Mar 24, 2014 at 12:39 | comment | added | Lnafziger | All INS units that I am aware of have max drift rates specified in NM/Hour so is linear. | |
| Mar 24, 2014 at 12:10 | comment | added | fgrieu | @ratchet freak: From my minimal understanding of Inertial Measurement, the error in a purely inertial mode should grow as the square of the time; or at least significantly faster than linearly with time. That makes me doubt of that source, although I think it is much less far off than the bragging I quote. | |
| Mar 24, 2014 at 12:01 | comment | added | ratchet freak | the wiki article of INS states (unreffed) that "The inaccuracy of a good-quality navigational system is normally less than 0.6 nautical miles per hour in position and on the order of tenths of a degree per hour in orientation" | |
