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 satellite’s reported health state. It does not certify a position fix or the integrity of a receiver. Check the reception time alongside it; older broadcasts remain in the feed until they expire. Explore Integrity Satellite
