Simple geo coordinates conversion library

Essential transformations for PTZ units and conversion between global coordinate systems

Two Line Element position calculator using sgp4

Geodetic calculator (Geodetic tasks - direct and inverse; conversions between Geodetic, ECEF, ENU, AER, SK-42; Bursa-Wolf 7-parameters ECEF to ECEF)

The envector package is a suite of tools written in Python forked from the nvector package to solve geographical position calculations powered by means of n-vector.

PyGeodetics is a Python library for performing geodetic computations like geodetic inverse and direct problems, conversions between different reference systems like ECEF to ENU, ECEF to geographic etc.

This library provides different coordinate systems

A single-point positioning system for processing satellite data to compute positions, velocities, and clock biases, developed at the Technical University of Munich.

Lightweight, dependency-free WGS-84 navigation utilities: coordinate conversion, azimuth/distance, heading smoothing & Plus Code encoding

🌍 3D positions on Earth, made simple. Convert GPS coordinates to ECEF, local ENU/NED frames, UTM and heights above sea level, then find look angles, distances, areas and line of sight. Exact, tested, no dependencies, and runs on microcontrollers (no_std).
