Ukraine Is Jamming Russian Glide Bombs All Along The Front Line, Erasing One Of Russia’s Main Battlefield Advantages.

Without a steady connection for course correction, the glide bombs tend to stray and harmlessly explode on some fields.

Space has become very, very cluttered.

Satellite Tracker 3D is a premier platform for real-time, 3D tracking of over 24,000 satellites directly in your browser.

Starlink satellites are noticeably closer to Earth.

My newest topic I am trying to understand better: #GNSS

While trying to write about #NTP as well as #PTP another world opened up as well. Global Navigation Satellite System or #GNSS which is most often the source of time. Digging through the different Satellite constellations #GPS , #GALILEO , #BAIDU , #GLONASS and understanding the differences was interesting.

I am still digging deeper. Anyone with knowledge, is highly welcome to educate me.

Es gibt so billige USB Sticks, die entweder #GPS oder #GLONASS können...

Wenn ich jetzt zwei davon habe.
Einen auf GPS, einen auf GLONASS, kann ich die Infos dann irgendwie bündeln?

Kann gpsd unter #Linux das?

Ziel: Ich brauche einen sehr genauen Standort. Auf 0,1m genau.

Nur GPS reicht da nicht, daher die Idee, das zu bündeln.

(Hardware die gleichzeitig beides kann, gibt es kostet mir aber zu viel Geld)

I bought a #Garmin #Forerunner55 as a replacement for my Forerunner255
(Thanks for the recommendations)

While playing around with the setting I notices al activities that use GPS are set to GPS+GLONASS
(#GLONASS is a Russian satellite navigation system)

I'm a bit #WTF

Could you check if it is the same for you?

Just noticed that Pine64 maintain a nice table of the State of the software, that is about management of different hardware parts of the #PinephonePro, in their Wiki. There are some interesting links on each problems.

The GPS fix can take long time to work (case of Marble Maps), A-GPS help a lot (case of GNOME Maps and Organic Maps).

The tool #gpsmon can be used to monitor Pinephone Pro, Quectel EG25G Modem / #GNSS Receiver (specs) (that supports #GPS, #Glonass, #Galileo #Beidu and #QZSS GNSS satellite networks) . gpsmon is included in gpsd package, at least on Arch, Debian and their derivatives.

Serial communication with Quectel EG25G use /dev/ttyUSB1, using #AT commands Quectel manual about supported AT commands

@NK30 I do track that.

AFAIK #COMPASS should work.

Not shure if #GLONASS and #COMPASS are having "Selected Availability" aka. purposeful signal degradation enabled or can do it.

#Galileo is just an #AGPS system due to being purposefully #downgraded during design to be less secure and reliable than #NAVSTAR - #GPS, which can explain worse reception!

We (u-blox) just published a new page about RTK (real-time kinematic).
