Most seismic data have been integrated into national networks by data transmission via cellular telemetry to the Apollo server located at the national data center, except for RM-SZP which uses satellite telemetry.

The Apollo server is a platform for consolidating continuous real-time data seismic waveform, state-of-health data, and log files using Nanometrics Protocol (NP) or SEEDLink protocol which is the standard for exchanging earthquake data, thus making it compatible with SeisComP, seismic data acquisition, and processing software, used by most agencies.
