Ten years of experience in recording seismic signals using autonomous ROSA-A stations (Novosibirsk, Russia) in deep seismic studies on geological and geophysical reference profiles (2-DV, 2-DV-A, 3-DV, 1-SB, 8- DV) at distances of up to 300 km indicates the effectiveness of cable-free spatially distributed seismic systems. The ROSA-A autonomous station is designed to perform high-precision seismic measurements, including long-term (seismic monitoring), without preliminary time adjustment at any given mode of operation with various sources of elastic vibrations (explosive, pulse and vibratory).

Keywords: autonomous seismic recorder, time synchronization system, cable-free seismic recording system, deep seismic studies, basic geological and geophysical profile.
