Abstract

A seismic system, Seismic Mobile Information & Control System (Seis-MICS) comprising field resources, satellite resources, and office resources. The field resources include various personnel, equipment, and vehicles located in the general vicinity of the seismic project. The field resources include transceivers permitting various of the field resources to communicate directly, or indirectly, to the office resources via one or more satellites. The office resources include satellite earth hubs/stations, a server-side hardware, software, and data store, and user workstations. The seismic system advantageously facilitates real or near real time transmission of data between the field and office environment, thereby providing an efficient seismic operation.

Claims

1. A seismic system, comprising:

a plurality of field equipment usable in the vicinity of an area to be seismically surveyed, each of said plurality of field equipment including a satellite transceiver;

an earth station hub coupled to said plurality of field equipment through one or more communication satellites; and

a workstation coupled to said earth station hub;

said workstation and field equipment in communication with each other via said earth station hub;

further including portable personal data assistants and an antenna coupled to a satellite transceiver located in the field, said PDA communicates through the satellite transceiver to the earth station hub.

2. The seismic system of claim 1 further including a positioning subsystem comprising ground-based satellite receivers that receive signals from positioning satellites to determine receiver position data and transmit said receiver position data via said communication satellite to the earth station hub.

3. The seismic system of claim 1 further including connections to an on-line network to permit predetermined persons access to various seismic information.

4. The seismic system of claim 3 wherein said on-line network comprises the Internet.
