fajna rzecz. Nawet jeżeli zasięg jest słaby i dokładność mała, trudno się zgubić z czymś takim. Do tego dołożyć w miarę dobrą cyfrową mapę ( tu wymiata), i możemy planować tak, by maksymalnie wykorzystać dostępny czas. Kontrolować trasę, tempo, ewentualnie szybko zmieniać plany.

A co, kiedy GPS nie chce chwycić, a nasza trasa przemierza przez , gdzie trudno o jakiekolwiek konkretne punkty orientacyjne, i nie przebiega wyznaczonym szlakiem (albo o nim nie wiemy, bo nie mamy tak dobrej mapy)?

Wtedy też się da, a potrzeba czterech rzeczy: naszej dobrej cyfrowej mapy, początkowego punktu odniesienia, czasomierza i mniej-więcej stałego tempa. Przydaje się też magnetometr albo kompas. Nie jest może to tak wygodne jak automatyczna nawigacja, ale całkowicie do zrealizowania, i nie trzeba z niczego rezygnować.

Mamy już wstępnie wyznaczoną trasę, i orientacyjny czas dotarcia do celu. Określamy kierunek, odmierzamy jak daleko jest następny zakręt i wyliczamy jak długo będziemy szli. Potem zmieniamy punkt początkowy trasy i kiedy do niego docieramy, sprawdzamy, czy czas dotarcia do celu się zgadza. Skręcamy i powtarzamy całą zabawę.

Jest tu pewien marginalny konflikt — z jednej strony powinniśmy iść stałym tempem, żeby nam się czasy nie rozjeżdżały; z drugiej — chcemy iść jak najszybciej, żeby mieć maksymalny zapas czasu na wypadek, gdyby okazało się, że mapa gdzieś się nie zgadza i stracimy cenne 10 minut błądząc. Jednak jeżeli zakręty czy punkty orientacyjne są w miarę gęste, możemy łatwo potwierdzać minimalne zmiany czasu dotarcia do celu.

No i jeszcze jedno: jak już zabłądzimy, to przydaje się . Szukamy kolejnego słupka z numerami oddziałów. Oczywiście, w praktyce długo żadnego nie ma, a potem zastanawiamy się jak przenieść pozycję z jednej mapy na drugą, ale można sobie poradzić. W ramach przestrogi przypominam, że numery oddziałów czytamy "od środka" — tzn. jeżeli patrząc na wprost, na słupek widzimy 76, to 76 jest za nami, a oddział przed nami jest po drugiej stronie słupka.

Großbritannien versieht Tausende von Migranten mit GPS-Etiketten

"Knöchelanhänger, die ständig die Koordinaten einer Person aufzeichnen, sind Teil einer wachsenden Zahl von experimentellen Überwachungsinstrumenten, die Länder auf der ganzen Welt an Neuankömmlingen ausprobieren."

24/7 GPS monitoring of migrants enabled the UK Home Office to collect vast amounts of personal data, invading people’s privacy and inflicting psychological burdens.

It’s a punitive and offensive measure that has rightly been found unlawful by the Information Commissioner’s Office.

Looking for a gps logger that :

  • has a few days of autonomy
  • has enough memory for a few weeks of tracing at 18hours a day

Ideas, recommendations?

I use OSMand+

quite detailed, route mapper , etc. quite extensive features. maybe overkill for some. me says comparable to gMaps if not better.

it also has feature for users to contribute to based poi, , etc. .

if you looking for advanced features beyond , gander over to + app.

Pour revenir encore une fois sur Magic Earth, notez aussi que désormais le thème "Magic Day" affiche des couleurs spécifiques pour différentes zones. C'est très pratique pour les repérer rapidement sur la carte.

Tiens la nouvelle version de MagicEarth a deux nouveaux styles de cartes (Magic Day et Magic Night) avec des routes détourées et plus contrastées.
Ça rend vraiment très bien: c'est agréable à l'oeil et ça améliore la lisibilité. 👍🏻

published an AWESOME video about the very unlikely invention of the blue LED. It’s an incredible story and you really should view it. It also contains the best visualization of semiconductors I’ve ever seen.

I witnessed the drama of the blue LED live in the 1990s. I watched tech magazines show dim blue prototypes for years until Nichia suddenly burst on the scenes with a bright blue LED and it changed the world. I watched as they created their first white LEDs ($1 apiece) which I gawked at in person. I was at Honeywell when they finally made white LEDs in surface-mount format (still $1 apiece). We used 50 of them as the backlight in the aviation GPS navigator I worked on (at $50 the backlight was one of the most expensive components in the whole system). They were so hot (100 mW each for a total of 5 W) we used them as heaters when the unit was below operating temperatures.

When I read about how Nakamura got screwed by Nichia, I was livid.

Here’s the GPS unit: the Bendix/King KLN 94 (King Radio became Bendix/King became AlliedSignal became Honeywell Aerospace). The color display needed 5W of backlight to be sunlight-readable, provided by 50 Nichia white LEDs, surface-mounted on a custom white circuit board behind a diffusion filter.

The unit was operable to -40° C, but the LCD was sluggish below about -25° C. If you turned it on below the LCD operation temperature, we set the LCD to full black, turned off all the fans, and blasted the backlight to full power. 5W of heat would bring it up to temperature in a couple of minutes.

Non essendo questo un campo in cui siamo particolarmente esperti, ma siamo certi che a qualcuno questo GPSTest possa tornare molto utile, vi lasciamo tradotta una parte della descrizione presente su F-Droid:

GPSTest visualizza le informazioni in tempo reale sui satelliti in vista del dispositivo. Uno strumento di test open-source fondamentale per gli ingegneri delle piattaforme, gli sviluppatori e i power user.

Supporta:

  • GPS (USA Navstar)
  • GLONASS (Russia)
  • QZSS (Giappone)
  • BeiDou/COMPASS (Cina)
  • Galileo (Unione Europea)
  • Vari sistemi di potenziamento satellitare SBAS (ad esempio, GAGAN, Anik F1, Galaxy 15, Inmarsat 3-F2, Inmarsat 4-F3, SES-5).

I satelliti GLONASS sono rappresentati come quadrati nella vista Sky. Gli statunitensi NAVSTAR sono rappresentati come cerchi, Galileo e i satelliti QZSS e SBAS sono mostrati come triangoli e infine i satelliti BeiDou sono rappresentati come pentagoni.

jamming has been impacting parts of , and since just before Christmas. And in recent days, flights in the region have been targeted too.

These scare tactics, perpetrated by an actor with significant GPS-jamming capabilities, are leaving the region’s governments with a tricky dilemma: How exactly do they retaliate once they’re certain who’s behind it all?

Evidence points in one particular direction: Russia.
