Open source navigation project for GPS and Internet denied regions
Hey everyone, I wanted to share what I have been working on recently. I had this itch for a long time to figure out if terrain contour matching could help with ground navigation, by only only relying on iphone's sensors and public data. So far I have had decent results. This is a working prototype, but there is a lot that is in the pipeline. If you notice anything weird, let me know or open a PR. Any feedback, comments are welcome :)

What it does
Navigation when there is no GPS and no Internet. Contribute to deepanwadhwa/anumaan development by creating an account on GitHub.
Anumaan (Hindi: अनुमान) means "to estimate", or "to reckon roughly". The main goal of this project is to figure out and implement an app which can help with navigation without GPS or Internet. GPS and Internet coverage has only gotten better and I think it will penetrate even more remote parts of the world with more satellites in the orbit. The reason for building this is to satisfy my own curiosity and also answer the below hypothetical: "Scenario: internet is down, lower earth satellites have been shot down and GPS is jammed; how would you navigate from point A to point B?" This is an imaginary scenario and it will probably never happen, right? Number 3 is hard because that is exactly…from github.com

Building a GPS receiver2024 · axleos.com · ▲552Hi 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…
Tiny FOSS Compass and Navigation App (<2MB)Jan 2026 · github.com · ▲137Hey HN, This is a follow-up to our original Show HN post, where I launched the first version of MBCompass. https://news.ycombinator.com/item?id=44155741 Since then, I've added several features based on user feedback and community input... I just released v1.1.9 of MBCompass - Minimal, FOSS compass and navigation app. New in this version: - Theme toggling (Dark/Light) controlled via settings - Fix current location arrow visibility - Compass accuracy alerts - Sensor status indicator - Explicit button for showing the GPS current location - Smooth transitions and many more..…
3D Terrain simulation for hiking, skiing etc.2025 · github.com · ▲150I'm working on a GPS track visualizer for quite some time. It shines in hilly and mountaineous terrain (where a 3D view makes more sense), but it also offers quite a lot of Strava-like features (statistics etc.). You can upload your GPX and FIT files manually, or sync directly with Garmin, Coros and Polar. See https://cubetrek.com for the live app and check out some examples there. It's free and opens source. Also, anyone who likes to work with 3D visualizations (especially Babylon.js), let me know if you like to help polish this thing further.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
