"Before GPS became an everyday utility, it was a hard mathematical problem.
In the 1950s–70s, Gladys West, a mathematician at the U.S. Naval Surface Warfare Center in Dahlgren, Virginia, worked on one of the most difficult challenges in satellite navigation: accurately modeling the Earth itself.
Modern GPS accuracy depends on:
• Precise satellite ephemerides
• Accurate gravitational field modeling
• Correct Earth reference frames
West’s work directly advanced all three.
Her contributions weren’t widely recognized at the time. In fact, it wasn’t until 2018 that she was inducted into the U.S. Air Force Space and Missile Pioneers Hall of Fame—decades after GPS reshaped global navigation, logistics, finance, defense, and mobile computing...
Before GPS could tell us where we are, someone had to define what the Earth actually looks like—mathematically…”

Bon fuck finalement je ne vais pas prendre l'abonnement MagicEarth.
CoMaps est désormais parfaitement bon pour la navigation en voiture, et dans les rares cas où j'aurais besoin de l'info trafic, le passerai par Waze (que j'ai bien pris soin de configurer pour que l'appli ne puisse pas tourner en arrière plan).
#GPS
La note de MagicEarth sur le PlayStore est descendue à 1,4 (elle était à 4,2 à l'origine)
Félicitation aux robots-corpo fraîchement sortis des écoles de commerce qui ont dicté cette refonte 👌
#GPS
1,9 étoiles sur 5.
Ah ouais avec leur dernière mise à jour, MagicEarth a très bien réussi à cramer sa note sur le magasin GooglePlay. 👌
#GPS
Bien... CoMaps est absolument fantastique, c'est juste la navigation voiture qui posait problème. La dernière mise à jour a enfin un zoom automatique adapté au prochain changement, ce qui rend la navigatation *bien meilleure*.
L'indication des sorties est également amélioré (on a par exemple les numéros des sorties).
Pour ceux qui l'utilisent en voiture, il devient enfin *acceptable* et peut remplacer MagicEarth (info-trafic mise à part).
Pour autant, il n'est pas parfait: (suite)
#GPS
mmm... le changelog de la dernière version de CoMaps indique un changement intéressant, un reproche que je faisais à *TOUTES* les applications de GPS (sauf MagicEarth) : Un niveau de zoom automatique foireux et des intersections illisibles (coucou OrganicMaps).
Le niveau de zoom est maintenant adapté automatiquement à la distance du prochain embranchement, ce qui devrait en principe rendre l'utilisation en voiture nettement meilleur.
Je teste ça et je vous tiens au courant.
🛰️🇵🇱 GPSPATRON & Gdynia Maritime University analyzed GPS/GNSS Interference in the Baltic Sea over the last 9 months.
⏱️ 84 hours of GNSS interference (mostly jamming) detected.
📆 This October had 6 jamming incidents for 29 hours. It's intensifying ↗️
✈️ No correlation between terrestrial GNSS and ADS-B-interference
🚢 Maritime jamming sources were identified, with interference signals exhibiting movement patterns consistent those of vessels.
🛰️🔒 Galileo began yesterday encrypting the E6-C signal component of satellites E14 and E18, the two spacecraft in eccentric orbits currently used for testing.
These signals will remain encrypted from now on, and we expect the rest of the constellation to follow in the coming months. This marks a key step toward Galileo Signal Authentication Service (SAS), the civil and free spreading code protection service.

Studie: GPS-Störungen in der Ostsee werden komplexer und stärker
Bei den Unterbrechungen von Satellitennavigation bei Kaliningrad kommt es laut einer Analyse mittlerweile zu einem Wechsel von Spoofing- und Jamming-Angriffen.

Donc la nouvelle version de MagicEarth est sortie. Et c'est pas fameux. ☹️

Bon ben ça y est, je suis passé à la nouvelle version de MagicEarth.
C'est pas fameux 🙁
Et je ne parle même pas du fait qu'une partie est devenue payante.
J'essaie de vous faire un topo dans la journée.

Mit GPS-Trackern am Halsband sollen sich entlaufende Hunde jederzeit orten lassen. Wir haben getestet, ob das wirklich funktioniert.
