Strange free INS coasting error about navego HOT 2 CLOSED

Dear kmos,

First of all, thank you very much for your words of encouragement!

With respect to your comment, what you are experiencing is the normal operation of an INS without any aiding sensor. The time the INS starts diverging depends on the quality of the inertial sensors. This time can be around seconds for a MEMS IMU and around hours for a navigation-grade IMU.

Regards.

Dear rodralez,

thank you for your quick reply. Sorry my fault, I was wrong, but if it seems strange, It's exactly what I need for the beginning of my master thesis work: I was comparing the ins error without an aiding sensor and I thought that for a MEMS IMU the performance was better than in five seconds, ten meters of error.

Anyway, it could be a nice (new) feature to compare the same imu with different kalman filter.
