Thanks for an excellent explanation..

Thanks this really helps me !!

Great explanation!!!

thank you very much🙏🙏

It should be noted that There are AHRSes that have GNSS as well and use that to do sensor fusion. on the other hand there are INSes that come with no GNSS but accept the data from a separate sensor.

All right~

You mistook the IMU rate with the GPS rate. IMU runs at around 1Khz while GPS is very slow, around 5~10hz only. IMU cant be used for navigation alone, because of the huge drift it accumulates over time. the accurate IMUs used for military and space projects range from 100K to around 1M$ dollars. the cheap IMUs that we use are good enough to be used in manual flight, where you control the robot. in autonomous robots, you need to have good IMUs along with other means of navigation like GPS or odometry for proper navigation.

So the difference is basically the detail level if the software. Got it.
