Upgrade and Addition of Equipment at YBH

The BSL Station YBH was initially installed in July of 1993. Since that time, instruments and telemetry have been reconfigured several times. In 1996 a geodetic GPS receiver was added to the site. In 2002 an second seismometer (STS-2) was installed and added to the existing datalogger on behalf of CTBTO.

During November of 2004, CTBTO requested a site visit to install UPS power on their auxiliary instrumentation and telemetry (VSAT) at the site. BSL engineers took this opportunity to replace the strong motion FBA-23 with a newer model Episensor, as well as replacement of the telemetry FRAD.
