EKF red status and flags

When initialize navio2 with ardu copter, I got constantly red flag of EKF, and two flags are off, as in the picture, is it ok to fly? what could be the problem?

It should be from the GPS not having a good fix yet. It clears as soon as GPS fixes with good hdop.

@anon67614380 im also facing same EKF flag issue, i have calibrated compass even at good gps fix its showing same error

@roishachar its not advisable to fly when EKF error persists it will crash

The issue was solved when relocating the gps antenna higher and way far from the flight controller
