The results of in situ tests of fiber-optic seismometers designed for use in the mobile segment of the planetary laser interferometric seismoacoustic observatory are presented. The 3D measurement system includes fiber-optic horizontal and vertical accelerometers and a horizontal strainmeter. It is shown that the system records acoustic signals generated by a hydroacoustic emitter at a distance of up to 12 km.
