"How Airspeed Sensors Work" by @hackaday@hackaday.social - #GPS & #GNSS 🛰 can tell ground speed for purposes of navigation. But flying an airplane🛨🛧 or glider first requires airspeed. Piloting at takeoff, landing, cruise and maximum "red line" are all by airspeed. Airspeed differs from ground speed by wind direction/speed you're flying in. Airspeed is measured via a pitot tube (French word: silent t on the end) which looks like a forward-facing spike. https://hackaday.com/2026/06/30/how-airspeed-sensors-work/ #aviation #pilot #avgeek #science

#ESA: " Galileo signal updated for internet-of-things use " "In April, .. deployment of a new signal component, known as E5a Quasi Pilot, on 12 satellites .. .. upgrade makes Galileo signals easier to access, particularly on emerging mass-market, low-power devices used for Internet of Things and smart city applications." https://www.esa.int/Applications/Satellite_navigation/Galileo/Galileo_signal_updated_for_internet-of-things_use 19.6.2026 #E5aQP #Europa #Europe #Galileo #GNSS #IoT #Raumfahrt #Satelliten #Satellitennavigation #SmartCity #SpaceFlight

Replying to
@thanetric@mastodonapp.uk But so to would Artemis 2. In the reference frame of the Solar system's barycentre, Ted and #Artemis2, whilst not co-moving, have similar paths now that they are both on Terra. We'd need to pick a reference frame closer to home, where Artemis 2 is now stationary and Ted continues to move. WGS-84 is the obvious choice, I think. I suspect Ted is already being measured in it. I *definitely* wouldn't pick one with a billionaire as the origin point. The billionaire hopping onto a private (or even public) jet would make it seem like Artemis 2 was moving once again. Aside from complicating what is already a non-inertial frame, this seems like cheating to keep raising Artemis 2's total. (-: Artemis 2 does get legitimate credit for a few thousand extra km, though, because the service module took its own path around the globe after separation from the crew module. @GetCarter@mastodonapp.uk#astronomy #physics #GNSS #GPS
