MongoDB. How to organize a search by gps coordinates?

Question

satellite navigation

Good afternoon. I have MongoDB and am having some issues with it.
1) In what format is it best to store gps coordinates in mongodb, for further search on them?
2) I use Java, how to organize the search for the necessary gps coordinates (stored in Mongo) that are included in a given circle? I will be very grateful if you give an example

On the backend, you simply run queries
