I still think engineering for slow internet is really important, and massively under appreciated by most software developers, but ... LEO systems (like Starlink, especially StarLink) essentially solve the core problems now. I did an Arctic transit (Alaska to Norway) in the summer of 2023, and we could make FaceTime video calls from the ship, despite cloud cover, being quite far from land. The polar coverage... - Source: Hacker News / 15 days ago

You can look at the https://satellitemap.space/ to see that starlink isn't (yet) too feasible in the northern/arctic areas. Even in the Nordic countries the connections are not that great. - Source: Hacker News / 19 days ago

This one has been around for ages, and it does work on mobile too. https://satellitemap.space/. - Source: Hacker News / 3 months ago

Some fun things I spotted: - https://satellitemap.space/?constellation=starlink&norad=59207 is rising, started recently? - There's one over Africa that says re-entry in 30 minutes. - Source: Hacker News / 3 months ago

I prefer https://satellitemap.space/ You can see the base station locations there, which is helpful in visualizing how the system works in various locales. - Source: Hacker News / 3 months ago

My site has this but only for satellites. https://james.darpinian.com/satellites/ For OP I'd suggest doing calendar events for notifications rather than Web Push. Web Push is very difficult to set up, users are suspicious of it, and it doesn't guarantee timely delivery on Android devices. Calendar events work well on mobile. - Source: Hacker News / 3 months ago

I bet it is used in a lot of ways people don't notice. In my site[1] I use wasm to run an ancient piece of code called SGP4, but it's totally invisible to the user. Someone actually ported SGP4 to JavaScript but it's slower and doesn't perfectly match the original, so it's great to have the option to run the real C version (actually the original is Fortran but the C port is the standard these days).

I live 10 miles from Boston and I've seen them a whole bunch. I've used https://james.darpinian.com/satellites/?special=starlink. - Source: Hacker News / 5 months ago

Https://james.darpinian.com/satellites/ Put in your location and it will tell you when and where to look at the sky to see one. Works great for me and hopefully it will work for you. - Source: Hacker News / 5 months ago

Starlink Go to this site. It will tell you all the satelites in your area and what time they will pass over you. It will also tell you how many starlink satts will be in the 'train' . Most I have seen was 54 travelling east west and 52 travelling north south. And passed in the middle. That would have totally freaked out a few people. Https://james.darpinian.com/satellites/.
