Important Hardware/Software Notes for Researchers Using PASSCAL Equipment

This page includes important Hardware/Software Notes for Researchers Using PASSCAL Equipment. January 17, 2019: GPS Rollover

Late 2018 PASSCAL learned of a GPS week rollover event that can affect data logger performance and timing. PASSCAL has acquired a GNSS signal generator that can emulate GPS satellite signals. This satellite emulator allows us to test PASSCAL equipment that relies on GPS timing and to determine how equipment will handle the GPS rollover event. To date, we have determined that some models of GPS engines are affected by the rollover. How the rollover errors manifest is dependent on the data logger’s model and firmware version of the GPS engine.

Magnetotelluric Systems at PASSCAL

Magnetotelluric (MT) methods are used to produce conductivity models of the crust and upper mantle through the recording of geoelectric and geomagnetic field variations at the Earth's surface. Depending on the period of the recordings, these methods can provide results from a few hundred meters depth (short period) to 30 km or deeper (long period). Conductivity is a physical property, which is complementary to seismic velocity, and which is very sensitive to the presence of fluids. When seismic and MT data sets are measured together, the additional data can dramatically improve determinations of the structure of the crust and mantle.
