For the Pre-Arming Checks to show that Navigation is safe, RubiQ must be connected to satellites.
At the end of a successful configuration, the Pre-Arming Checks will have all categories showing a green check mark except for “Navigation is safe.”
This is because RubiQ comes with GPS lock enabled, which means she won’t fly without first connecting to seven satellites, something she can only do while out at the flight field. Once she’s locked onto the satellites, “Navigation is safe” will give you the green light.
