ASTRONOMICAL TIME SIGNAL GENERATOR FOR STAND-ALONE DIGITAL SEISMOMETERS Russian patent published in 2023 - IPC G01V1/16 G01V1/24 

FIELD: seismology.

SUBSTANCE: seismic signal receivers used to create seismic data recording systems. The claimed device contains a GPS receiver and a logical level converter. Additionally, a clock generator is introduced into the device, a controller for maintaining the parameters of the second mark, which has a program contained in it, which ensures that the period of signals of the second marks, if any, is measured, it is stored in the internal memory of this controller and the signals of the second marks are reproduced at its output when the signals stop receiving second marks from the GPS receiver.
