This is a
gpsd
server
located someplace .
The hardware is a
UPUtronic GPS, RPi 5 .
This machine is maintained by
Steve G6UIM.
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 ,
red=worst ,
blue=less than 10 degrees ,
and black=SNR less than 10 .
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.
