Description
T4.3
The CTBTO site station in Parapat (AS043), North Sumatra has been losing data since 2020. This has resulted in the loss of important data for analysis. Data analysis from SQLX shows the seismometer in good condition and noise spectrum still within HNM / LNM limits. The site station has used solar panels but this is not enough. Solar panel energy cannot supply battery power effectively. The...
Most waveform stations in the IMS network are now 10-20 years old. Problems with power and communication systems often relate to cables, circuit breakers, connectors and/or surge protection becoming corroded or deteriorated to a point where good connections and functionality can be compromised. Many stations are located near the sea, in high humidity and salty environments, which inevitably...
Radio frequency (RF) systems are used at large number of IMS waveform stations for transmitting data and State-of-Health parameters from the array elements to the Central Recording facility. Main operation and maintenance challenges experienced over time are related to equipment obsolescence, aging, material deterioration or harsh environmental conditions. RF equipment must receive regular...
Equipment is mission critical for CTBTO verification pillars. Within the 3 Divisions of CTBTO, IMS, IDC and OSI, the categories and volumes of equipment are increasing with the non-stop and quick development of the verification infrastructure. Equipment management could be either an efficiency improving factor or bottle neck for the functioning of CTBT verification engines, like a double-edge...
Among the monitoring stations include the RN42 which is located in Cameron Highlands, Pahang, Malaysia. Generally, the task to monitor the status and result of the radioactivity spectrum is quite a tedious job. The radionuclide analyst at the International Data Centre (IDC) in Vienna, Austria analyzed around 21 to 25 spectrum data every day. Automatic products help the analyst to perform...
Since the migration to GCI – III it has been observed that there are multiple instances of failure of data transmission when there is an operational GCI-link. Elements for significant consideration in the analysis phase examined why, when the GCI link is available, data transmission stops but subsequently backfills indicating that there is some element in the overall data path that is...
General Dynamics Mission Systems (GDMS) is seeking ways to improve the maintainability and scalability of its applications and IT infrastructure by leveraging emerging cloud technology and best practices. The cloud offers many advantages over traditional IT infrastructures including greater flexibility, reduced cost, improved backup solutions and faster deployment cycles.
GDMS cloud...
This study proposes the development and implementation of a tool for recording and consulting the problems that occur at the station. The application to be implemented internally in the station, which can be mobile, would record the incident and once the event has been added, a group of contacts would be notified about the problem that occurred and its solution. In turn, the application would...
Based on statistics and experience in station installation and operations, IMS/ED in cooperation with OVE developed a comprehensive guidelines/company standards for a grounding and lightning protection system at IMS stations. The document's first edition was issued in 2010 and then revised in 2018-2019.
The document provides comprehensive information for the design and implementation of the...
Due to the large amount of information that is created with a new event and its relocation, the SeisComP3 (SC3) Database size tends to increase and the backup process becomes increasingly time-consuming.
At CATAC (Central American Tsunami Advisory Center) we created a data import mechanism, to send the information referred of every event from the main database to three other real-time...
Remote places, away from crowded areas, where anthropic noise cannot affect the quality of the measurement characterize the site of installation of a seismological station. However, these sites are generally difficult to access, located in places where there are no traditional energy and communication systems, or the access to maintenance facilities affects its operability. This condition...
The IMS hydroacoustic (HA) network monitors continuously the world’s oceans with only six hydrophone stations (11 triplets). The acoustic signals acquired by the hydrophones are digitized underwater and transmitted via fibre-optic cable to an on-shore Digital Data Formatting Interface (DDFI). The DDFI builds data packets and sends these to the Commission’s Standard Station Interface (SSI),...
The Provisional Technical Secretariat (PTS) is the entity assisting the Preparatory Commission in the establishment of a global verification regime to monitor compliance with the comprehensive ban on explosive nuclear testing.
In this digital era, efficient, secure, and pervasive IT services are key enablers allowing the PTS to fulfill its core technical mandate.
To modernize its office IT...
The PTS uses email (SMTP) as a transport mechanism for a portion of the verification data received from the IMS stations and laboratories and for data transmitted to States Signatories. Currently the PTS uses the email domain @ctbto.org for both its verification and non-verification email systems, forcing the sharing of resources and making it difficult to segregate the email flows and...
The Expert Communications System (ECS) is a secure internet-accessible application, sharing and strengthening the intersessional work of the Commission and its subsidiary bodies, that enables registered users from States Signatories, the Provisional Technical Secretariat (PTS) and a restricted observers’ number to the Preparatory Commission (PC) to access to official documents.
Users can...
The Station Standard Interface (SSI) is a modular software, consisting of a set of executable programs, application programming interfaces (API) and libraries. The main purpose of SSI is to collect, sign, buffer, reformat and transmit data using IDC format. SSI is used at more than 150 IMS stations in all waveform technologies as well as at several NDCs. The Web configurator has been the main...
OVSICORI is the institute in charge of earthquake and volcanoes monitoring in Costa Rica. Similar to other countries in Central America, we have limited economical resources. Thanks to an important government investment in 2010 we chose Antelope by BRTT as our main monitoring computational system. Antelope worked well for us at the beginning, but over the following years we found out that most...
