ESP32 + Neo-6M: Visualize Your Trajectory on a Cloud Map

ESP32 + Neo-6M: Visualize Your Trajectory on a Cloud Map

When it comes to GPS tracking, many people’s first reaction is that it is complicated: collecting latitude and longitude, setting up servers, databases, and drawing trajectories on a webpage. For an engineer looking to quickly validate an idea, these “infrastructures” can be more troublesome than the hardware itself. This project offers a refreshing approach: Using … Read more

Calculating Distance Between Any Two Latitude and Longitude Points Using Python

Ellipsoids Ellipsoid is a three-dimensional shape in geometry formed by rotating an ellipse around its major or minor axis. The shape of the Earth is not a perfect sphere but is closer to a flattened sphere, hence referred to as the “Earth ellipsoid.” Specifically, the Earth is slightly bulging at the equator and slightly flattened … Read more
