Space warfare: how the military could be forced to give up GPS and return to navigating by the stars
The military relies on space for communications, for position, navigation and timing (PNT) information, meteorology, intelligence, surveillance, and reconnaissance. Australia now recognises space as an operational domain, alongside air, sea, land an ...continues

On va pas se mentir, mais les calculs de trajets en transports en communs dans les grandes villes, avec changements et horaires, directement intégré à MagicEarth c'est de la balle !
(Et pas besoin d'avoir une application par ville).
If anyone is interested, I'm giving this old #GPS receiver away for shipping costs from Germany.
It's a Garmin eTrex (the first one from 1999-2002). It has an IPX7 case, a 64 x 128 4 level grayscale LCD display with a backlight. GPS doesn't work anymore due to the GPS week rollover, other components work great.
It's a bit sad that a really well designed handheld device became useless due to outdated software.
It was also a prop "scanner" in #Stargate SG-1 if someone does cosplay.
@acejacek I couldn't get a position lock, outside with a good visibility of the sky.
It locked 2 block IIF sats, but couldn't lock to a block III sat that was at a similar angular alt. I don't know if there are any differences between those, or just bad luck. Also I don't know what the rollover does to the coordinates.
If someone wants to play with it, to check if it's still possible to get a valid lock - have fun. But I don't want to over promise on the functionality.
@makdaam are you positive it’s software fluke? Sounds like a hardware issue. Just dug out my ancient gps logger from Wintec and it still fixes position correctly.
The solar storm that brought the auroras to many parts of the world this weekend also broke vital GPS and precision farming functionality in tractors and agricultural equipment during a critical point of the planting season, reports @404mediaco.
One chain of John Deere dealerships even warned farmers that the accuracy of some of the systems used by tractors had been “extremely compromised,” and that farmers who planted crops during periods of inaccuracy would face problems when they go to harvest.
The outages have highlighted the vulnerability of modern tractors to satellite disruption, and the threat this places on our food supply — something experts have been warning about for years. Here’s more.
#SolarStorm#GPS#Farming#JohnDeere: "The solar storm that brought the aurora borealis to large parts of the United States this weekend also broke critical GPS and precision farming functionality in tractors and agricultural equipment during a critical point of the planting season, 404 Media has learned. These outages caused many farmers to fully stop their planting operations for the moment.
One chain of John Deere dealerships warned farmers that the accuracy of some of the systems used by tractors are “extremely compromised,” and that farmers who planted crops during periods of inaccuracy are going to face problems when they go to harvest, according to text messages obtained by 404 Media and an update posted by the dealership. The outages highlight how vulnerable modern tractors are to satellite disruptions, which experts have been warning about for years."
A couple of weeks ago I finished a beast of a project.
The interactive installation (titled InStability) is an artistic endeavor to demonstrate how seismic stations in Iceland detect earthquakes.
Visitors are invited to touch the map, triggering "earthquakes", and observe how LEDs, representing seismic and GPS stations, light up as the seismic waves propagate across Reykjanes peninsula.
For the soundscape I used a modified recording from Earthtunes. The audio is made from actual seismic data, recorded in Grindavik last year on the 10th of November (when the town was evacuated). Here's a video so you can hear and see the installation in action:
