METHOD FOR TIME DRIFT MEASUREMENT, SEISMIC NODE AND SEISMIC NODE HANDLING SYSTEM

Method for time drift measurement of at least one slave clock in at least one seismic node, wherein the time drift measurement is performed in the at least one seismic node. The seismic node is configured for receiving a master clock signal and obtaining a time drift between the slave clock and the...

Zusammenfassung:Method for time drift measurement of at least one slave clock in at least one seismic node, wherein the time drift measurement is performed in the at least one seismic node. The seismic node is configured for receiving a master clock signal and obtaining a time drift between the slave clock and the master clock signal. La présente invention concerne un procédé de mesure de dérive temporelle d'au moins une horloge esclave dans au moins un nud sismique, la mesure de dérive temporelle étant effectuée dans le ou les nuds sismiques. Le nud sismique est conçu pour recevoir un signal d'horloge maîtresse et obtenir une dérive temporelle entre l'horloge esclave et le signal d'horloge maîtresse.
