Network Characteristics
Information listed below includes both the core national network and additional western stations
- ~30 broadband stations across the country, sampled at 40s/s (~90 channels)
- ~35 short-period stations in western Canada, sampled at 100s/s (~35 channels)
- All stations employ continuous, packetised digital telemetry with GPS timing at the outstation
- broadband stations use CMG-3ESP, CMG-3T or STS-1VBB seismometers
- short-period stations use S-13 seismometers
- 24+ bit digitizers for both broadband and short-period stations (developed in-house)
Standard Earthworm Modules in current use
Earthworm (v3.0) is in the process of being installed
on a Pentium II system under NT4.0
Earthworm Modules under development
modules to receive packetised CNSN data and output ew
trace_buf packets are under development - later versions
to handle two-way dialog with outstation and requests
for retransmission of data
Needs
- Continued improvement of documentation
- Easy data exchange with neighboring networks (Washington and Alaska)
