Python

Hello guys... I have a critical issue in one app that needs assistance, I want to detect fake GPS in a web app (ReactJS) on the frontend and in the backend in Node (but if there is a perfect package in Python, I can create a microservice to detect fake GPS)... Please suggest to me if there are any Python package which works well to detect mock GPS. Note: if the user changes location by approximately 50-100 km, then it should also work. Thanks
