This is a chrony time server with gpsd
running on a Raspberry Pi with a TimeHat!
A filled shape means the satellite was used in
the last fix.
Green-yellow-red colors indicate signal to noise ratio in dBHz
green=best,
yellow=fair,
and red=worst.
Circles are GPS and QZSS satellites.
Diamonds indicate augmentation (SBAS, WAAS, etc.) satellites.
Triangles pointing up are Galileo satellites.
Triangles pointing down are BeiDou satellites.
Squares are GLONASS satellites.
