Geobit Instruments will not be affected by the “week number rollover” issue on 29th May 2021

Geobit Instruments are not affected by the GPS week rollover issue.

We are pleased to inform you that all GEObit digitizers are using Garmin GPS receivers for time synchronization, and they will not be affected by the GPS rollover issue on 29th May 2021. As a result, all our digitizers will continue operating properly. No action needs to be taken by GEObit Instruments users.

At GEObit, we are always working to offer state-of-the-art technology and high-reliability products, requiring the minimum possible maintenance.

What is the GPS Week Number Rollover (WNRO)?

The GPS system is world renowned for its ability to provide accurate and reliable positioning and timing information worldwide. The GPS satellites transmit to users the date and time accurate to nanoseconds. However, back in 1980, when the GPS system first began to keep track of time, the date and time were represented by a counter that could only count forward to a maximum of 1024 weeks, or about 19.7 years. After 1024 weeks had elapsed, this counter “rolled over” to zero, and GPS time started counting forward again.  This first rollover occurred in August of 1999. The second rollover occurred on April 6, 2019. Several rollovers will happen in the future, depending on the manufacturer and the production date of the GPS receiver.

Is My Geobit Device Affected?

Our GPS supplier, Garmin, has anticipated and prepared for this event. Regardless, Garmin and Geobit have been performing exhaustive testing of current and legacy devices to determine if they will be affected by the GPS week number rollover.  Our testing shows the vast majority of Geobit devices will handle the WNRO without issues.

What is the Effect of a GPS Week Number Rollover Issue?

For GPS devices that are affected, after the rollover occurs, an incorrect date and time will be displayed. This incorrect time will also be used to timestamp track logs, compute sunrise and sunset, and other functions that rely upon the correct date and time. However, the positioning accuracy will not be affected. The device will continue to deliver the same positioning performance as before the rollover.

GEObit joins at the EUROVOLC 3rd Annual Meeting, 1 – 8 March 2021. 

We provide state-of-the-art seismic instruments, network design, installation techniques, data monitoring and processing services. Our group is able to deliver a cost-effective total solution to the energy exploration & production industry, especially to the oil, gas and geothermal sector. Our key benefits are that we produce in-house hardware and software while installing and maintaining the microseismic monitoring network to ensure a high level of data quality and availability. In other words, we make the technology – we apply the technology – we offer the technology.

We have worldwide experience having installed and operated seismic networks all over the world, from Indonesia/Papua jungle to the Middle East desert, from Alaska glaciers to Himalayan Mountains. In the USA, we are currently running many dedicated microseismic monitoring projects with over 200 stations installed in the past 10 years.

The Broadband Era

The Broadband Era

The arrival of the new year, 2021, marks the beginning of a new era in the history of Geobit. We are introducing the first Force Balance Accelerometer, the GEOfba200.

Currently, we are also working on the development of the Force Balance Accelerograph, which will be available in the market in the next couple of months.

Following our policy to provide low-cost quality instruments, the new FBA offered at a very competitive price. We implemented smart technologies, including AI techniques in order to produce a high technology instrument which will become a point of reference.

  • Low noise accelerometer for high precision and high dynamic range
  • Selectable full scale range +/-4g to +/-0.25g standard, higher gain set custom available
  • Wide passband DC to 215Hz, higher corner frequency custom available
  • Simple installation using a central fix bolt
  • Electronically adjustable DC offset
  • Power 9-18Vdc, 1.2W
  • Waterproof IP68 aluminum or stainless-steel casing

The GEOfba200 is a very low-noise triaxial force-balance accelerometer with a large dynamic range, suitable for seismology, hazard mitigation and civil engineering applications. The instrument has both a flat response to ground acceleration from DC to 215 Hz and a stable phase response within the passband. Output range is 40Vpp differentially and supports variety range of gain sets from +/-4g to +/-0.25g in the standard configuration and availability for higher gain set under request.

Due to it’s high dynamic range which exceeds 155dB the sensor provides from on-scale recording of earthquake motions to structural seismic noise monitoring and allows engineers to study motions at higher frequencies. The sensor allows easy field calibration through its calibration line.

GEOfba200 sensing element mechanism

Inside the GEOfba200 there are three similar accelerometers, orthogonally placed. The sensor is operating according to the force-balance principle as closed-loop sensor (servo accelerometer).

The motion of the seismic mass is monitored from a very sensitive capacitive transducer and a very low noise VHF preamplifier. The demodulator generates in-phase and low noise seismic signal which is fed back to the seismic mass through a phase compensator, a power amplifier and a fully symmetrical force actuator consisting of a double coil-magnet system. This design eliminates any non-linearity due to lack of symmetry. The output amplifier sets the selectable acceleration gain between +/-4g to +/-0.25g.

The virtual posters will be available to registered meeting attendees only.

Why is this named eLightning?
In 2016, AGU piloted a Lightning Poster Session format that allowed poster sessions to have a set time, outside of their designated time in the poster hall and in a separate room, for their presenters to give lightning presentations of their posters. This experiment was intended to encourage discussion, enable presenters in the same session to see each other present, and increase visibility of the posters. The current session format is built on the progress made and lessons learned from Lightning Poster Sessions, hence the Lightning in eLightning. We are adding additional value by providing more of an electronic ability, hence the e in eLightning. We also wanted to make sure that it wouldn’t be confused with our long-running ePoster program, where poster presenters are able to upload a static PDF copy of their poster to the online scientific program, so the word poster wasn’t included in the name.
