Notes:

(*)	Signal strength is mapped between 1 (worst) and 9 (best), 5 is the threshold for good SNR, 0 indicates value is unknown
(#)	A complete GPS observation contains non-zero L1 code and phase measurements with a SNR of at least 0
(#)	A complete GLONASS observation contains non-zero G1 code and phase measurements with a SNR of at least 0
(#)	A complete Galileo observation contains non-zero E1, E5a code and phase measurements with a SNR of at least 0
(#)	A complete BeiDou observation contains non-zero B1I code and phase measurements with a SNR of at least 0
(#)	A complete QZSS observation contains non-zero L1 code and phase measurements with a SNR of at least 0
(#)	A complete NavIC observation contains non-zero L5 code and phase measurements with a SNR of at least 0
(-)	The minimum duration of a data gap to be reported is 5 seconds
(^)	A satellite has to be above the elevation mask with no observations recorded for at least 120 seconds to be reported
-	The elevation mask is set at 15°
-	Abbreviations: Av=Average, IOD=Ionospheric delay, Num=Number, Obs=Observations, MP=Multipath, SV=Satellite vehicle, Elev=Elevation, Nav=Navigation data (ephemeris), WLF=Wavelength factor
