| Jun 7, 2016 at 22:17 | comment | added | John Birckhead | @Kozuch I guess I stand corrected! I can't see how a bare mems gyro can approach this level of bias. Do you know what the term "in-run" bias stability means? Is there specmanship going on here? | |

| Jun 7, 2016 at 21:53 | comment | added | Kozuch | The Xsens gyros and Analog Devices iSensor gyros are both MEMS and can do around 10 deg/hour at best. Both priced in $100s or lower $1000s (depending on accuracy). The entry level units do around 20 deg/h for about $200-300 which I think is very good value still. | |
| Jun 7, 2016 at 21:45 | comment | added | John Birckhead | Yes. When still, this gyro will report that it is slowly turning by this amount. The type of gyro you want is going to be a navigational grade and pretty expensive. Typically they have a caged spinning mass, sometimes powered by a hysteresis motor. I haven't heard of any solid state gyros that approach this accuracy. | |
| Jun 7, 2016 at 21:13 | comment | added | Kozuch | Ok, so they call it "Zero-rate Offset" - I am looking for a higher quality gyro with say bias up to 20 degrees/hour. So this Bosch will give typically 1*3600 = 3600 degrees/hour. | |
| Jun 7, 2016 at 21:07 | comment | added | John Birckhead | The bias is typically +/- 1 degree/sec, worst case +/-3 degrees/sec on page 14. (not useful as a north seeker). | |
