The 6th IWGoRS Workshop was held at the Institut de Physique du Globe (IPG) in Paris.The workshop re-focused on every aspect of gradient-related ground motion, including rotation and deformation recording, instrumentation, earthquake sources, custom rheology, inverse problems, surveying, seismic engineering, long-term seismology, planetary seismology, derivative rotation and strain, correlation studiesnoise, ring laser technology, Earth rotation, seismic decoupling, fundamental physics, and more.
Anna Kurzych Ph.D., from FOSREM team showed presentation: “Recording of the rotational events in Poland – Time horizon & Fascinating Future of Fiber-Optic Seismograph”
Members of the 6th IWGoRS Workshop
Anna Kurzych Ph.D. and Jerzy K. Kowalski Ph.D. show the sensor and its applications.
The International Timing and Sync Forum, the world’s largest event on timing and synchronisation, kicked off on Nov 7th in Düsseldorf. For years, industry leaders have been coming together at the conference to showcase their companies’ latest synchronisation solutions.
All visitors are welcome to visit the Elproma Electronics booth, where Tomasz Widomski will answer all questions related to the revolutionary www.fosrem.eu project and modern time servers www.elpromatime.com
During September 18-22, 2022, Paris, France, will host the world’s most important event in the space sector – the International Astronautical Congress (IAC). On this occasion, the Polish Space Agency (POLSA) will organize an exhibition booth promoting the Polish space sector. The POLSA booth will additionally provide a gathering point for representatives of the Polish space sector at IAC, so that participants may conveniently meet with Polish aerospace companies in one location.
The pending FOSREM project new technology will be presented and explained in 2022 during 30th International Defence Industry Exhibition MSPO. We show our FOS6 project, especially in future defence applications. You can get information about the project and possible applications at the stand (B-23) of the Polish Space Agency (POLSA).
FOSREM team replaced the previous FOS1 sensor with the new FOS5LL with a 15 km long fiber loop. The old one was working since July 2017 and give us a lot of data. The new FOS5LL (Long Loop) is ten times more accurate, has a long 15000 m fiber optic loop and 1.5 m diameter. It’s working in a closed-loop configuration with 1310nm light.
The 4th IWGoRS workshop were held at the Evangelische Akademie Tutzing (near Munich, Germany), June 20-23, 2016. The workshop was focus on any aspect of rotational ground motion including the recording of rotations, instrumentation, earthquake sources, non-standard rheologies, inverse problems, geodesy, earthquake engineering, long-period seismology, array-derived rotation, noise-correlation studies, ring laser technology, Earth’s rotation, problems of fundamental physics and others.
Our team has prepared one oral presentation and two-day demonstration of mobile Fosrem System in action. The presentation given by Prof. Leszek R. Jaroszewicz is avaiable here. Also Fosrem System data sheet is avaiable for download.
Our team announces that new mobile FOG sensor FOS2/3 is ready for operation. We have done several tests, simulating different types of earthquakes and standard waves.
It’s a mobile, fiber-optic system, based on Sagnac interferometer for monitoring rotational events and phenomena. The sensor device is optimized for measurement of the rotational rate with sensitivity equal to 2*10E-8 rad/s/Hz in pass band from DC to 327,68 Hz. The above mentioned sensitivity as well as rotation rate dynamic range up to 10 rad/s covers weak as well as strong rotational motions connected with irregular object movements, occurring during strong winds, tectonic moves and earthquakes. In this way, the developed system is dedicated to monitoring the rotational vibration in such objects as wind power plants, tall irregular buildings, bridges, and unstable grounds as well as rotational events connected with earthquakes.
