24 alternatives to Global Ground Station Database – 650 Satellite Ground Stations Mapped
Hi HN, I've been working on a project to address a challenge I faced in the space industry: finding reliable and comprehensive information about satellite ground stations. It often involved piecing together data from scattered sources, which was time-consuming and inefficient. So, I built the Global Ground Station Database (www.find-gs.com). It's a free, searchable directory of over 650 ground stations worldwide, with locations mapped and key details included. The database is built with [Python + React]. We're focused on data accuracy and completeness, and we're constantly adding new…

Hi HN, After 9 years of running my own OpenStreetMap tile server infra for MapHub (https://news.ycombinator.com/item?id=11389989), I've open-sourced it and launched OpenFreeMap. You can either self-host or use our public instance. Everything is open-source, including the full production setup — there’s no 'open-core' model here. Check out the repo (https://github.com/hyperknot/openfreemap). The map data comes from OpenStreetMap. I also provide weekly full planet downloads both in Btrfs and MBTiles formats. I aim to cover the running costs of the public…

Over the last year, I've worked on aggregating Groundhog data, including predictions, location, and a cute photo. Welcome to GROUNDHOG-DAY.com: The clean and breathable, machine-readable, all-regional data source for Groundhog Day forecasts. Find your fave groundhog, peruse past predictions, or trek the continent-wide Groundhog Map. Includes enterprise-grade API for corporate use cases.

I made this site using R3F (https://github.com/pmndrs/react-three-fiber), a React renderer for 3JS (https://threejs.org/). The celestial bodies are Three.JS meshes. I used loaders (namely 'useLoader' from R3F and 'GLTFLoader' from 3JS) to import 3D models, such as International Space Station. More on loading models in R3F: https://docs.pmnd.rs/react-three-fiber/tutorials/loading-mod... I've future plans for this side project. It would be great to hear from the HN community before diving into them. Enjoy! P.S: Getting an empty…

Hi HN, I made a web game to practice country locations a while ago and HN liked it, so I thought I'd post my updated version as well. As for how the game works and feels, I'd really recommend you checking it out for yourself, it's free, no signup, no ads. The tech stack is Vue + ts + Tailwind/Daisy for the looks. The learning algorithm is a slight modification of the ts version of FSRS. If you have anything to add, it's open source as well (https://github.com/koljapluemer/learn-worldmap), although not well documented yet. In the end it's just a little sideproject,…

This was something I built while trying to look for housing in Toronto that was decently transit-accessible to my office while still cheap. The backend is written in Rust. It parses public GTFS data from transit agencies and performs a simple heuristics-based BFS on the bus lines to calculate how long to reach all points in a city. The frontend uses React and Mapbox GL to render each individual road segment based on how long it takes to reach. This project was a great excuse to learn Rust, deployments, and mapping. The source code is here if you are interested:…

Hi everyone! Shortly after publishing my iOS 4 jailbreak last October[1], I got to work on my next hobby project: a from-scratch homebrew GPS receiver, which can solve the user’s location solely from billions of radio antenna samples. I took a commodity SDR (alongside the Python standard library and numpy) and built a signal processing pipeline that can detect and track GPS satellites over many minutes, drop and pick up satellites as they come in and out of view, and precisely determine the user’s position and clock inaccuracy. All told, gypsum can go from a cold start to a fix on the user’s…

Over the past week I built a project to let people self-host an entire maps stack so they don't have to send data to the big G. Right now it includes a base map, geocoder and directions server. Currently only bicycle directions are supported, and I'm only hosting tiles for Seattle because I'm unemployed and can't afford to host data for the whole planet. Check it out! https://maps.ellenhp.me/ https://github.com/ellenhp/headway Ultimately I'd like to really focus on transit routing (not implemented) but I'll probably throw a driving mode in there too.

Hello Hacker News community, I'm excited to share my open-source project, Ground Station – a full-featured software solution for satellite tracking and radio communication. Designed for amateur radio operators, satellite enthusiasts, and researchers, it provides a comprehensive and easy-to-use platform. Key Features include: - Real-time Satellite Tracking: Precise orbital models and automatic TLE updates. - SDR Integration: Stream and record live radio signals from a wide range of SDR devices (RTL-SDR, SoapySDR, UHD/USRP). - AI-Powered Transcription: Real-time speech-to-text for…

This is a little hobby project that I hope you enjoy. You can see where the International Space Station is now, with live HD video from NASA, on a realistic 3D globe. The positions of the sun and moon are also accurate, though distances aren't to scale. The clouds are also near-realtime; I span that out into a separate project at https://clouds.matteason.co.uk, where the cloud images I create from EUMETSAT data are freely available. I've got more features almost ready to go, like the ability to turn off all UI, toggleable clouds and turning off the day/night cycle I'd love for…

Hi all, I am not an expert in nuclear energy but I've always wondered and found it difficult to get a clear picture about the amount of nuclear stations located in a specific region. So I built this tool that shows all the nuclear plants in the world, scaled by their capacity and with indication of their status. Clustering is enabled by default and allows to see the sum potential capacity of a region. It's a fun tool for me: e.g. disable clustering, scale circle radius to 70%, go to EU, and you'll see Germany has shutdown all of the stations. Ofc it's a widely known fact, but what came to my…

This is a service I've built to provide equirectangular cloud maps of the whole Earth, updated every 3 hours, for free. It's based on infrared and visible light data from EUMETSAT, processed to enhance the clouds and try to reduce the impact of surface temperatures on the final image. I built it because it's surprisingly hard to find these kinds of images in a format that's useful to developers and hobbyists. I was building a 3D ISS tracker and wanted to include live clouds but couldn't find anything good, so I got sidetracked, and here we are.
