In preparation for CSRS-PPP's upcoming upgrade to their precise positioning
service I recently got in a new 8 channel GNSS antenna amplifier/splitter that
does GPS L1/L2, Glonass, Galileo, Beidou. I connected one channel to a Ublox
M8T and enabled GPS, SBAS, Glonass, and Galileo.
Attached is a plot of the sky view. It was tracking 28 satellites with usable
signals. There were actually 38 satellites visible. If Great Britain gets
kicked out of Galileo and goes ahead with their plan to do their own GNSS
system, we're gonna need a bigger sky ;-)
I also recently added a feature to Lady Heather that lets you select a specific
satellite and plot its azimuth, elevation, and signal level over time.
Attached is a plot of GPS PRN6 from horizon to horizon. With my antenna
location (horrible) anything below 25 degrees is really bad. Once you get
above 35 degrees things really settle down.
