Specification goals for a Mars seismic network [PDF]
A seismic network on Mars should have enough stations (e.g., 24) to characterize the seismicity of the planet for comparison with a diversity of structural features; be comprised of low noise stations, preferably underground, 3 to 4 orders of magnitude ...

Comparison on seismometer sensitivity following ISO 16063-11 standard
Computer Integrated Manufacturing, 2019 Accelerometer calibration by primary and secondary means is now very well covered both in low and medium frequency range. This is obviously not the case for seismometers which are widely used in the world.

Simulation of underground gravity gradients from stochastic seismic fields
, 2009 We present results obtained from a finite-element simulation of seismic displacement fields and of gravity gradients generated by those fields. The displacement field is constructed by a plane wave model with a 3D isotropic stochastic field and a 2D ...

Seismometer Calibration Using a Multi-Component Acceleration Exciter
Journal of Physics: Conference Series, 2018 Seismometers are widely used all over the world, but rarely calibrated traceably. PTB analysed its capabilities for seismometer calibration and identified its multi-component acceleration exciter as suitable for carrying the comparably heavy seismometers.

Viking‐2 Seismometer Measurements on Mars: PDS Data Archive and Meteorological Applications
, 2017 A data product has been generated and archived on the NASA Planetary Data System (Geosciences Node), which presents the seismometer readings of Viking Lander 2 in an easy‐to‐access form, for both the raw (“high rate”) waveform records and the compressed (

Self-attraction effect and correction on three absolute gravimeters
, 2012 The perturbations of the gravitational field due to the mass distribution of an absolute gravimeter have been studied. The so called Self Attraction Effect (SAE) is crucial for the measurement accuracy, especially for the International Comparisons, and ...
