Claim 13:
14. A data acquisition unit for acquiring seismic data for ambient noise tomography (ANT) processing at a server system, including:
a housing;
a ground movement data acquisition mechanism configured to measure ground movement;
a processing unit communicatively coupled to the ground movement data acquisition mechanism, the processing unit contained in the housing;
a modem communication port positioned on a top portion of the housing, the modem communication port for allowing communication between a satellite modem and the processing unit to transmit data payloads to a satellite;
a power source;
power source holding structure in a central portion within the housing, the power source holding structure securely holding the power source in the central portion; and
a power supply in the housing configured to supply power from the power source to the processing unit and the satellite modem;
wherein the processing un it is configured to receive ground movement data sent from the ground movement data acquisition mechanism, the processing unit further configured to pre-process the ground movement data including performing one-bit normalisation, and process the one-bit normalised ground movement data to generate data payloads before transmitting the data payloads, via the satellite modem, to a communicatively coupled satellite; and
wherein the processing un it is configured to store the pre-processed ground movement data, before forwarding, at a scheduled time period, the data payloads containing the pre-processed ground movement data to the satellite modem for transmission, or wherein the processing un it is configured to generate and forward the data payloads containing the pre-processed ground movement data to the satellite modem for transmission.
