Race against the clock to spot locations from the sky 🚀

    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…

    I'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.

    I find myself often texting people, "where are you?" so I wrote this little iPhone app that lets me text them a special link. When they click the link, it uses the HTML5 geolocation API to report their location and shows it on a map. http://whru.at/ It's only as accurate as the HTML5 geolocation API, but I've been finding it pretty useful. What do you think?

    For a game I'm developing I needed an easy way to create hotspot areas on images. So I hacked together a small tool to do so and before I knew it, I had created an entire app :-) It allows you to generate JSON or YAML from the coordinates you tack on the image. tack runs entirely in your browser, there is no server side component to it, so good in terms of privacy. Hope this is helpful.

    Hello HN, I started building GeoSpoof after I noticed my IP says one country, but the browser still hands sites my real location. Websites were flagging me because of this discrepancy. I searched for a good geolocation spoofer, only to go down a rabbit hole that there are dozens of signals that your browser emits and no tool could cover them all on every platform. GeoSpoof overrides every location-related API to present one consistent signal for location. You can search a city, enter coordinates, or hit "Sync with VPN" to auto-detect your exit region and match it, which re-syncs when you…

    Scheduling meetings across multiple time zones has always been painful for me, especially across daylight saving time transitions. So I built a visual timeline that makes it easy to find overlapping availability. Add your locations, drag to select a time range, and share a link. Recipients see the proposed times in their local time zone automatically. A few things that might be interesting: * Location search over GeoNames with fuzzy matching using weighted edit distance, so typos and partial names still resolve correctly. * Shareable links encode the selected time range and locations in a…

    I'm working on https://cubetrek.com, a web app to manage, visualize and compare your running, hiking, mountainbiking, skiing... activities. Some features include: a github-style calendar heatmap, 3D visualization of tracks (especially useful for hill climbs and mountaineous terrain in general), a world map displaying all your activities at once. Excluded features: although you can share yoir tracks to the world, should you choose so, there are no friends, no likes, no comments, i.e. none of that social networking stuff. And no ads. Any feedback is appreciated, let me know what you…
