Lakkolit X-M2 Digital Multi-Channel Seismic Station

The station is used for seismic surveying during geophysical research by means of refracted and reflected waves. The station includes one or several LAKKOLIT 24-M2 units and a laptop computer or a specialized control unit. Each unit is responsible for receiving data from 24 seismic channels and their preliminary processing.

The number of channels depends on the number of units. The LAKKOLIT X-M2 ships with a 12V battery and a charger. The computer is responsible for control of the units, further processing of the acquired data, and visualization of results. It is connected to the network via Ethernet adapter. Data transfer rate is 10 Mbps.

Acquired data might be transferred across local area network via radio-Ethernet. This option enables remote control of equi pment within 500 m thus allowing for operator control from weather protected premises.

The seismic station needs one operator. Unit design ensures reliable performance in harsh conditions within wide temperature range.

Optional Equipment

Channel Switchboard

Digitally controlled channel switchboard (supplied as an option) allows doubling the number of seismic receivers (up to 48 sensors) simultaneously connected to the recorder. The switchboard makes it possible to realize any kind of common midpoint including central control system. The switchboard allows for registering from one setup a section profile equal to two seismic cables length with 24 sensors each, which cuts down the operation time. The switchboard features user friendly interface.

Specialized Control Unit

Specialized Control Unit controls LAKKOLIT X-M2 and does preliminary processing of the acquired data at a wide temperature, luminosity, and humidity range.
The Control Unit features digital signal processors.
Boasts the following characteristics:

Low power consumption;
Compact size and small weight;
Works within a wide temperature range;
Has LCD display with 640x480 resolution capable of working in temperatures ranging from -20° to +50°С;
Has a built-in GPS receiver; the data is automatically transferred to the SEG Y format.

Time Break System

The Time Break System consists of a receiving unit, transmitting unit, receiving antenna, and transmitting antenna. The Time Break System allows for remote LAKKOLIT X-M2 seismic station launch synchronized with the source of seismic vibrations via radio channel from a distance up to 500 m. This option significantly reduces data acquiring time and makes the station management more convenient by eliminating noise vulnerable synchronization cables.

Field Seismic Cables and Seismic Picups

The Field Seismic Cable is optional. Cable type (including the one intended for work in harsh environment), its length, and span between seismic pickups can vary. As per customer requirement the required number of seismic pickups are also supplied.

Software

LAKKOLIT X-M2 software is compatible with Windows 9x, 2k, XP. Convenient interface ensures quick and easy control of the station. Graphic capacities allow for immediate analysis of the acquired data. The software allows for use of PC or a specialized Control Unit as a central data collection unit of the local area seismic network.
