GPS position in Mission Planner with the car's position does not match

GPS position in Mission Planner with rover position does not match

How should I fix it?

Is there any way to recommend?

Go outside and try again.

Jokes aside, we need more information to be able to give you helpful advice.

Where are you? (inside, outside between buildings, outside with clear view of the sky,etc)
How much does the position differ? (a few meters, a few kilometers, many kilometers, different planet)

What GPS do you use? What FC do you use?

I can now fix my GPS.
