The potential of high-rate GPS for strong ground motion assessment (2017)
Journal Article
Michel, C., Kelevitz, K., Houlié, N., Edwards, B., Psimoulis, P., Su, Z., …Giardini, D. (in press). The potential of high-rate GPS for strong ground motion assessment. Bulletin of the Seismological Society of America, 107(3), https://doi.org/10.1785/0120160296

We show that high-rate GPS can have a vital role to play in near real-time monitoring of potentially destructive earthquakes. We do this by investigating the potential of GPS in recording strong ground motions from earthquakes in Switzerland and Japa...

Investigating multi-GNSS performance in the UK and China based on a zero-baseline measurement approach (2017)
Journal Article
Msaewe, H. A., Hancock, C. M., Psimoulis, P., Roberts, G. W., Bonenberg, L., & de Ligt, H. (2017). Investigating multi-GNSS performance in the UK and China based on a zero-baseline measurement approach. Measurement, 102, https://doi.org/10.1016/j.measurement.2017.02.004

GPS is the positioning tool of choice for a wide variety of applications where accurate (cm level or less) positions are required. However GPS is susceptible to a variety of errors that degrade both the quality of the position solution and the availa...

Consistency of PPP GPS and strong-motion records: case study of Mw9.0 Tohoku-Oki 2011 earthquake (2015)
Journal Article
Psimoulis, P., Houlié, N., Meindl, M., & Rothacher, M. (2015). Consistency of PPP GPS and strong-motion records: case study of Mw9.0 Tohoku-Oki 2011 earthquake. Smart structures and systems, 16(2), https://doi.org/10.12989/sss.2015.16.2.347

GPS and strong-motion sensors are broadly used for the monitoring of structural health and Earth surface motions, focusing on response of structures, earthquake characterization and rupture modeling. Several studies have shown the consistency of the... Read More about Consistency of PPP GPS and strong-motion records: case study of Mw9.0 Tohoku-Oki 2011 earthquake.

Measuring sub-mm structural displacements using QDaedalus: a digital clip-on measuring system developed for total stations (2014)
Journal Article
Charalampous, E., Psimoulis, P., Guillaume, S., Spiridonakos, M., Klis, R., Burki, B., …Feltrin, G. (2015). Measuring sub-mm structural displacements using QDaedalus: a digital clip-on measuring system developed for total stations. Applied Geomatics, 7(2), https://doi.org/10.1007/s12518-014-0150-z

The monitoring of rigid structures of modal frequencies greater than 5 Hz and sub-mm displacement is mainly based so far on relative quantities from accelerometers, strain gauges etc. Additionally geodetic techniques such as GPS and Robotic Total Sta...

Long-period surface motion of the multi-patch Mw9.0 Tohoku-Oki earthquake (2014)
Journal Article
Psimoulis, P., Houlie, N., Michel, C., Meindl, M., & Rothacher, M. (2014). Long-period surface motion of the multi-patch Mw9.0 Tohoku-Oki earthquake. Geophysical Journal International, 199(2), https://doi.org/10.1093/gji/ggu302

We show that it is possible to capture the oscillatory ground motion induced by the Tohoku-Oki event for periods ranging from 3 to 100s using Precise Point Positioning (PPP). We find that the ground motions of the sedimentary basins of Japan were lar... Read More about Long-period surface motion of the multi-patch Mw9.0 Tohoku-Oki earthquake.
