Q3. What does a GNSS module output?
A GNSS module outputs position, velocity and time — your PVT solution — typically as latitude, longitude, altitude, speed and a synchronized clock signal (PPS). It also reports satellites-in-view, signal strength and DOP. The standard output format is NMEA 0183 over UART or USB; high-precision GNSS modules additionally output raw carrier-phase data for RTK and post-processing.
