Description
T4.4
The Colombian Geological Survey (SGC) has its headquarters in Bogota, Colombia, where most of the technical and administrative personnel are located. However, its main activities are in the field. The National Seismological Network has monitoring stations countrywide. Due to this centralized scheme, preventive and corrective maintenance takes up to 45 days after planning, This is not a good...
IMS infrasound station I51GB, located on the island of Bermuda in the Atlantic Ocean, was certified in December 2008. The original installation presented many design challenges driven by land availability, island topography and proximity to populous zones. These challenges not only dictated the amount of elements that could be installed, but also the geometry of the station. The array...
After 25 years of reliable operation, PS19 (GERES) was modernized in 2017/2018. It was the first major upgrade since the station was certified as primary seismic IMS station in 2002. The German NDC operates PS19 remotely. The required data availability is ensured by preventive maintenance twice a year. The station consists of 25 array elements within an aperture of about 4 km. During the...
NORSAR is the Norwegian National Data Centre (NDC) and operates six stations of the International Monitoring System. These are the primary seismic arrays NOA/PS27, ARCES/PS28, the auxiliary seismic array SPITS/AS72, the auxiliary single seismic station JMIC/AS73, the infrasound array IS37 and the radionuclide station RN49. It is crucial to have a good overview of the state of the various...
Expanding upon flow analysis efforts presented in SnT 2019, General Dynamics Mission Systems (GDMS) has developed a field deployable system to validate the performance of mass flow meters at International Monitoring System (IMS) radionuclide stations with Radionuclide Aerosol Sampler/Analyzer (RASA) systems. The Rig for Automated Flow Testing (RAFT) system can validate the factory...
Sandia National Laboratories is developing the Geophysical Monitoring System (GMS) for modernization of the United States National Data Center waveform processing system, including data acquisition, automated processing, and interactive analysis. The United States is providing the common architecture and processing components of GMS as a contribution-in-kind to accelerate progress on...
The Preparatory Commission is tasked to make all necessary preparations, in fulfilling the requirements of the Treaty and its Protocol, for the support of on-site inspections (OSIs) from the entry into force of the Treaty. The OSI Technology Testing Program (TTP) is meant to support these preparations. The specific challenges and the unique nature of an inspection is making the synergy between...
Botswana Seismological Network(BSN) have deployed a countrywide state-of-the-art network of 21 autonomously recording broadband stations. The sensors deployed in the BSN are the Streckeisen and the Nanometrics Trillium 120. A relatively low cost in-house developed NARS Dataloggers developed by the seismology group and the Instrumental group of the Physics department of Utrecht University is...
Hydroacoustics is the only verification technology of the International Monitoring System (IMS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) to be fully certified. Five T-phase stations and six hydrophone-based hydroacoustic stations monitor the world oceans 24/7 for signs of nuclear explosions. Hydrophone stations comprise triplets of underwater microphones, called hydrophones,...
The seismic station AKASG (PS45) is located at the territory of Ukraine. From 2000 to 2002, the station had been being upgraded according to the CTBTO requirements. From 2003 to 2010, the station was operating within IMS, the most important problem in the station data presence during that period was the radio link system, used at the station. From 2010 to 2011, the new modernization project of...
Analysis of state of health (SOH) data from radionuclide systems can provide information beyond alerts and system diagnostics. Careful analysis of the data can help detect degradation of sensors that may help predict when a failure may occur or the remaining useful life (RUL) of components. In some early work performed by Pacific Northwest National Laboratory (PNNL; US), high-resolution SOH...
