Hi Park,

That’s not an error message, it’s just the hardware and software of your GPS unit.

Regarding the other EKF message I’ll the need to see the exact message because that “Check 0” doesn’t ring any bells to me.

Hi Park,

The message EKF_CHECK-2 means that EKF is going over the variance limits and triggering the EKF failsafe. The message EKF_CHECK-0 means the variance has gone down and the failsafe was cleared. Having all those isn’t normal and you should check what is happening.
