C# SGP4 orbit prediction Library

MML (Minimal Math Library) - A comprehensive, single-header C++ mathematical library for numerical computing

Layout, drag and drop, scroll, relative positioning features and more that SwiftUI is missing

This is a C++ library meant to provide implementation of the most commonly used geodetic algorithms.

Projections iOS Library

Miscellaneous Python functions.

A robust TypeScript library for converting between different geographic coordinate formats: Decimal Degrees (DD), Degrees-Minutes (DM), and Degrees-Minutes-Seconds (DMS). Features comprehensive parsing, validation, and formatting with support for hemisphere indicators.

Polars plugin for coordinate transformation and more

Projections Java Library

I imagine myself as a poor man's Copernicus and, using my basic understanding of orbital mechanics, built an app to find the position of the sun in the sky at any location in the world on any date and time!

Run PROJ on the browser, and use the grid files remotely.

This library provides different coordinate systems

Scalar Magnitudes are invariant quantities that conserve their value and form under transformations of translation and rotation, or changes between coordinate systems (Cartesian, polar, spherical, etc.)

A C++ library for geodetic engineering. Provides core algorithms for least-squares adjustment, coordinate transformations and geometric object modelling

Relational Magnitudes are invariant vectorial quantities that conserve their value and form under transformations of translation and rotation.
