Pi 5 — Satellite (GPS)
Satellites Visible
Number of GPS satellites in view. You need at least 4 for a positional fix, but 8+ satellites are recommended for stable NTP timing.
Signal Strength
Signal-to-Noise Ratio per satellite in dB-Hz. Values above 30 are good, above 40 excellent. Low SNR indicates poor sky visibility or antenna issues.
