  1. The levels are reported for the short-period instrument on the InSight Mission (SP), a typical strong-motion accelerometer commonly used in seismology (the EpiSensor ES-T from Kinemetrics, USA), and two navigation-grade accelerometers as parts of 6DoF freedom North-seeking gyros (PHINS and IMU50 from iXblue, France). The Quartz Vibrating Beam accelerometer iXal A5 from iXblue, France is the basis for PIONEERS compact sensor
