Ant -1C
1C Seismic Node Introduction
Ant-1C is a small, smart seismic nodes with high reliability by EarthPulse Technology Co., Ltd. It is used to reduce the difficulty forseismic exploration production, greatly improve the efficiency andlower the cost for project. The Ant-1C has integrated GPS/BDS clocksynchronization algorithm, ultra-low power design method, mostadvanced wireless charging and wireless pulse communication technologies. It is highly integrated, no connectors with long battery life, which is potential used for automatic deploy and retrieve. The Ant-1C is high reliable to be used in any harsh environments. And the newanalog-digital conversion technology is used to greatly improve thedynamic range rather than other equipment.
