How much accuracy can you expect from an IMU? -- Singularitarian ( talk) 18:18, 23 May 2008 (UTC)
Like a lot of other engineering components, there are a wide variety of configurations and various degrees of accuracy and percision at various price points. There realy is no general answer to that question. —Preceding unsigned comment added by Alan.A.Mick ( talk • contribs) 15:33, 18 November 2010 (UTC)
There's another kind of IMU called "gyro-free". Indeed, 6 or more accelerometers in a "good" configuration could be used to measure linear acceleration and angular acceleration. All this in "Feasibility of A Gyroscope free Inertial Navigation System for Tracking Rigid Body Motion" Tan, Mostov Varaiya (200), Institute of Transportation Studies, University of California, Berkley.
Also, I consider that an INS is a system that generally contains and IMU but it contains another subsystems like a GPS, a computer, a memory bank for map data and so on. The IMU could be called the sensor part of the INS. Crodrigue1 ( talk) 17:40, 21 May 2009 (UTC)
DARPA's Microsystems Technology Office( MTO) department is working on a Micro-PNT ("Micro-Technology for Positioning, Navigation and Timing") program to design "TIMU" ("Timing & Inertial Measurement Unit") chips that does absolute position tracking on a single chip without GPS aided navigation. [1] [2] [3]
Micro-PNT adds integrates a highly-accurate master timing clock [4] integrated into a IMU (Inertial Measurement Unit) chip, making it a "TIMU" ("Timing & Inertial Measurement Unit") chip. So these TIMU chips for Micro-PNT have integrated 3-axis gyroscope, 3-axis accelerometer, and 3-axis magnetometer, and together with the integrated highly-accurate master timing clock it simultaneous measure the motion tracked and combines that with timing from the synchronized clock, and with sensor fusion it makes a single chip that does absolute position tracking, all without external transmitters/transceivers.

Much of the technical discussion incorporates discussion of specific fields of study where IMUs are applied. I think it'd be worthwhile to break these out into an applications section e.g. driverless cars, wearables, robotics, consumer electronics, etc.-- Keithicus ( talk) 16:44, 26 June 2018 (UTC)
The last sentence the section is "Calibration will typically improve sensors raw performance by at least two decades." Decades makes no sense for a sensor. Perhaps it should read decibels. The first reference from google scholar for 'inertial measurement unit' finds "Calibration of a MEMS inertial measurement unit" at https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.65.5896&rep=rep1&type=pdf From the conclusions of the paper: "Simulation results shows that the mean square error of the parameter estimates of the senor model increases with up to 8 decibel, when utilizing the proposed method." Perhaps someone that knows what they are talking about can look at this. I'm not that person. — Preceding unsigned comment added by 2603:8001:7C3F:A436:E04E:879E:6202:EF08 ( talk) 17:36, 7 March 2021 (UTC)
