A little context for the numbers
GNSS is the family of satellite systems used for navigation and timing. These counts describe this collector’s public observations, not the total satellites in orbit or the sky at your location. Multiple signals from the same satellite are grouped together.
Broadcast health, with reception in view
“OK” is a signal’s reported health state. Pre-operational GPS L5 flags are shown separately from other signal flags; the original broadcast report remains in the details. Neither reception nor a reported health state certifies a position fix or receiver integrity. Check each signal’s reception time; older broadcasts remain in the feed until they expire.
