EarthOS geodesy, orbital transforms, astronomy, and spatial indexing

location storage with hexagons

A really dumb Piksi emulator that outputs position solutions at 1HZ (hardcoded) and echos observations written to it. This is for testing external streams of corrections and that they're getting to a piksi correctly.

A Cesium plugin providing a scene tree panel and tileset configuration for 3D Tiles datasets.

A JavaScript library for two-body Keplerian orbital propagation and Walker Delta constellation generation

can geohash and generate hexagons with icosahedron as base

The World Is Not Flat

React + Three.js (R3F) 3D Earth, satellites and orbit rendering, with a pure-TS orbital core

hexagon geohashing (depends on geocomb-cpp)

Bitruvius SDK pure 3D-Tiles streaming engine (gaussian splat, textured mesh, point cloud): codec- and renderer-agnostic traversal, cache, scheduler, and ENU packing (no WebGL/DOM/MapLibre)

High-performance ENU (East-North-Up) orthonormal basis generator with ESM/CJS/IIFE support for WebGL/graphics projects

Gaussian splat tile plugin for 3d-tiles-renderer backed by Spark.

GIS核心库

In-memory geohash heatmap. Does not visualize, but constructs an in-memory index of latlongs that you can query to determine density of areas.

Transforms and helpers for OGC GeoPose (Basic Quaternion and Basic YPR).

meteo-layer 渲染器无关内核：解码(含 Go wasm 内核与 Worker)、调色板、格式注册、数据源注册、色标组件。可被 Cesium / MapLibre 等渲染器包复用。

meteo-layer 的 Cesium 渲染器：填色图层 / 风场粒子 / 拾取 / 格点值 / 垂直剖面（依赖 @meteo-layer/core）。
