I was reminded today of a program I already have for plotting #GNSS #GPS performance from a serial port on Windows - GNSSToolKit3. It works nicely and has many more views than my screenshot shows. This Is plotting from an indoor GPS puck connected to my #tinyGTC.

When the clouds cleared, and in this #Edinburgh urban environment, the #aurora was just visible early this morning, although not quite as bright as this Pixel Phone photo depicts!

#Pixel 10 Pro phone - claims X100 zoom. Believable? I tried it today, hand-held. It seems that the phone automatically post processes the image to produce a sharper result. Original and processed paired here. The #moon is at x80 as the moon more than covers the x100 field!

Just playing with #Meshtastic and - surprise, surprise - coverage is much better with a half-decent antenna, even if indoors. Surprised to see nodes as far away from #Edinburgh as #Belfast and #Darlington - if those positions are real, of course! What’s the white ring, BTW?
