CAPS

The Common Acquisition Protocol Server (CAPS) was developed to fulfill the needs to transfer multi-sensor data from the station to the data center. As nowadays more and more stations with co-located sensors like broadband seismometer, accelerometer, CGPS, temperature, video cameras, etc. are built up, a acquisition protocol is required, which can efficiently handle low and high-sampled data through one unified protocol.

Application

  • real-time data transmission from remote sensor to data center
  • center to center data transfer

Features

  • multi-sensor data transfer, e.g. waveform data, webcam images
  • redundant data transmission
  • ensures timeliness of data
  • on the fly reconfiguration
  • lightweight protocol for minimized packet overhead
  • archived and real-time data served through one protocol and one connection
  • reliable data transfer, retransmission of data in case of network outage or server restart
  • Web interface for server monitoring and data review
  • secure communication via SSL
  • fine-grained access control
  • connectivity to the SeisComP3 framework

CAPS is developed as a standard SeisComP3 application. It uses the SeisComP3 infrastructure for startup and configuration developed by Gempa.

The Earth Data EDR-217 incorporates the CAPS protocol, which was developed to fulfill the needs to transfer multi-sensor data from the station to the data center.
