do satellites use summertime... tl;dr: no.

they use Temps Atomique International (TAI) [1,2].

#GNSS time vs local time

#GPS time is a continuous time scale with no leap seconds, and #GALILEO System Time is also continuous and not affected by daylight saving time.
#BeiDou the same.

#GLONASS is likewise a GNSS time reference tied to the system’s own timing, not to seasonal civil clock changes BUT the use *leap seconds*, that hurts.

Garmin Forerunner 55 fica 40% mais barato em oferta no Magalu

Hat jemand folgendes Verhalten in einem Zug der Baureihe 440 beobachtet?

Zwei verschiedene Empfänger (Garmin eTrex 32x, Samsung Galaxy A52 4G) empfangen kein #GPS-Signal. Beim Garmin auch nach Reboot nicht.

Draußen auf dem Bahnsteig (beim Garmin inzwischen die Batterien entfernt) klappt alles.

Die Datenerfassung für #OpenStreetMap während der Bahnreise musste ich abbrechen, weil mein Garmin mit #GLONASS allein zu wenig Satelliten für einen stabilen, guten Fix empfing. 😔

@Wrewdison hopefully.not just #GPS but also other #GNSS (#GLONASS, #COMPASS) and #SBAS (#QZSS, #GALILEO, ...)…

• And no, that is not a typo nor error!

I was impressed by the rented #FordKuga, until, just 9 hours in, the satellite navigation system stopped receiving position information from any satellites. (Its satellite status screen shows outline bars for all of the satellites, instead of the normal solid ones. There's no clue in the doco, which typically for Ford does not match the real vehicle, what that means.)

A quick search of the WWW turns up a Kuga owners club forum, where threads about the Kuga sat nav breaking, including but not limited to aerial problems that require authorized mechanic intervention, date back as far as 2013.

Also interesting is that this 2025 model Kuga uses both the U.S.A. #GPS and the Russian #GLONASS; but there seems to be no mechanism for picking just one, nor one for adding #Galileo, which one would think to be an idea for the U.K. market.

I have one idea, a seemingly unrelated sounds setting that I turned on right before parking and coming back to the failure, to try.
