App «WristTopo» bringt Wanderrouten auf die Apple Watch

Meist greife ich zur Coros Vertix 2 wenn es um ernsthafte Touren geht. Einerseits wegen der hervorragenden Batterielaufzeit und auch, weil ich GPX-Daten auf die Uhr ziehen und diese für die Navigation nutzen kann. Wer stur mit der Apple W

It's FOSS article about CoMaps
CoMaps article: comaps.app/news/2025-07-04/ITS
It's FOSS article: news.itsfoss.com/comaps-launch

“CoMaps, you can download entire regions before you begin a trip for easy navigation in places without an internet connection or mobile network connectivity.”
“The user interface is clean and intuitive. You won’t need a manual to figure it out."
"Moreover, privacy is baked into the app."
"The map style itself is another highlight; it feels fresh, modern, and thoughtfully designed"

P.S. I like it too. It's easy to use, reliable enough, and I don't need to fear that “someone” is keeping its eyes on me :tony_happy:

Bei vielen von uns wird für die #Navigation wohl eine der beliebten Navi-Apps wie #AppleMaps oder #GoogleMaps zum Einsatz kommen. Dass es gerade auch im Hinblick auf quelloffene und community-basierte Anwendungen anders gehen kann, beweist die neue #Navi-#App @CoMaps, die seit Ende des letzten Monats im deutschen #AppStore zum #Download bereit steht und komplett kostenlos genutzt werden kann.

New paper out that I helped a little bit with: "A Demonstration of Interstellar Navigation Using New Horizons", where NSF NOIR Lab's Tod Lauer uses New Horizons images of the parallax Proxima Centauri and Wolf 359 (of Star Trek fame) to figure out the absolute position of New Horizons in near-interstellar space.

It's a very international collaboration, with participation from quite a few small-telescope observers in South America and Australia, and dedicated to the memory of a master Polynesian navigator who inspired some of the thought process. And Brian May too, because he's a friend of the mission.

My little role was in helping to analyze the pointing uncertainty in both the New Horizons and ground based data.

arXiv.orgA Demonstration of Interstellar Navigation Using New HorizonsAs NASA's New Horizons spacecraft exits the Solar System bound for interstellar space, it has traveled so far that the nearest stars have shifted markedly from their positions seen from Earth. We demonstrated this by imaging the Proxima Centauri and Wolf 359 fields from Earth and New Horizons on 2020 April 23, when the spacecraft was 47.1 au distant. The observed parallaxes for Proxima Centauri and Wolf 359 are $32.4''$ and $15.7'',$ respectively. These measurements are not of research grade, but directly seeing large stellar parallaxes between two widely separated simultaneous observers is vividly educational. Using the New Horizons positions of the two stars alone, referenced to the three-dimensional model of the solar neighborhood constructed from Gaia DR3 astrometry, further provides the spacecraft spatial position relative to nearby stars with 0.44 au accuracy. The range to New Horizons from the Solar System barycenter is recovered to 0.27 au accuracy, and its angular direction to $0.4^\circ$ accuracy, when compared to the precise values from NASA Deep Space Network tracking. This is the first time optical stellar astrometry has been used to determine the three-dimensional location of a spacecraft with respect to nearby stars, and the first time any method of interstellar navigation has been demonstrated for a spacecraft on an interstellar trajectory. We conclude that the best astrometric approach to navigating spacecraft on their departures to interstellar space is to use a single pair of the closest stars as references, rather than a large sample of more distant stars.

Lorry

Any of you Map/Chart/Hacker folks know if anyone has cracked the encryption on the charts that go through o-charts.org?

I am asking as someone who has paid, but they are so utterly painful to use in their stupid encrypted format, especially if you ever dare to change anything about your hardware, that they are essentially unusable. People use them on a boat, people drop their Chromebooks into a bilge full of horror - Shit like this shouldn't be wholly dependent on a systemid!

"Each spring, billions of Bogong moths (Agrotis infusa) migrate hundreds of kilometres south to the Australian Alps, guided by the austral night sky. The discovery that they can find their way using only the stars — reported in an 18 June Nature paper — makes this moth the first invertebrate to be observed using celestial navigation for long-distance journeys."

Bobbing Boat

Eight times in 3½ hours a boat crashed into me while I was tied up along the shore.

I have just moved the boat forward, leap-frogging two boats.

And in the process I myself hit 2 boats — inevitable, unfortunately, but I was unwilling to continue being crashed into by people for whom the wind is somehow a surprise.

Bobbing Boat

Six boats have crashed into me in the past 3 hours, scraping and bouncing all the way down the length of the boat. The wind is too strong for occasional- and hire-boaters but it doesn't stop them, so they get blown into me as they clear the trees.

I want to move but the strong wind also means I cannot move the boat. There are 2 boats immediately ahead of me and I could never clear them.
