No matter how much raw data has been collected from the survey site, it’s the results that your client values. When budgets get tighter, survey tasks become ever more time-critical and the process of interpreting acquired data must be as quick and easy as possible.

Coda GeoSurvey Productivity Suite integrates the tasks of analysing, tagging and mosaicing complex data sets – thereby ensuring faster and more precise results.

With Coda GeoSurvey running on multiple workstations with remote networked data storage, high volumes of geophysical data can be managed and processed quickly, maximising productivity.

Survey Engine Seismic+ is a ‘next generation’ 2D seismic data processing, interpretation and reporting application for the marine survey industry.

Built on the years of experience that have made CodaOctopus’ software solutions a market leader at the heart of geophysical operations worldwide, Seismic+ brings survey tools up-to-date with the latest database and GIS technology. Based around a flexible database, Survey Engine gives fast access to all survey information, even from the largest data sets. As a result, Seismic+ offers exceptional time-saving advantages when reviewing data and performing interpretation. Designed with thousands of line kilometres of survey data in mind, we believe that Survey Engine Seismic+ is the most productive and intuitive tool available for seismic data processing, interpretation and reporting.

Seismic+ integrates fully with Sidescan+ so that both sidescan and seismic data sets can be used in the same project yielding interpretation productivity benefits.

Based on the RTS PPS Distribution Panel, the RTS PPS Box is a highly compact and robust solution for distributing GPS timing signals to survey spreads.

The unit features low latency distribution of one timing telegram together with PPS pulse to seven separate outputs. The RTS PPS Box is typically used for time synchronisation of sensors and logging systems.

• Seven-channel RS232 + PPS splitter
• Supports baud rates up to 115kbps
• Full RS232 levels (+/-8V)
• PPS TTL Level
• Low Latency
• Data and PPS indicators

The RTS PPS distribution panel is the key solution for distributing GPS timing signals to survey spreads. It can be used to distribute one or two separate timing telegrams together with PPS pulse.

The system consist of two RS232 splitters combined with three PPS pulse splitters. Selectable PPS pulse width, 500us, 1ms or directly from the GPS. Selectable PPS trigging, positive or negative edge. Typically used for time synchronisation of logging systems and multiple sensor synchronization.

• Two eight-channel RS232 splitters
• PPS pulse width extender
• Supports baud rates up to 115kbps
• Full RS232 levels (+/-8V)
• PPS TTL Level
• Low Latency
• Data, PPS and power indicators
• ESD-protected inputs
• Selectable PPS trig

Multichannel distribution panel for RS232 data communication. Commonly used in the maritime, survey and ROV industry. Simplifies and makes a well-arranged interconnection between RS232 sensors and multiple computers.

The panel allows up to eight different sensors to be interfaced up to four different computers, each. Data traffic indicators and magnetic isolation on each input channel. Solves problems with differences in ground potentials and also acts as a signal amplifier and cable extender.

• Eight channels with four RS232 output splitters
• Supports baud rates up to 230kbps
• Data and power indicators
• 1000V magnetic isolation
• Duplex port
• ESD protected inputs

RS232 splitter for distribution of sensor signal to multiple computers. Simplifies setups and make a well arranged interconnection between computers and sensors. No more unpredictable RS232 signals caused by serial ports connected in parallel. A special duplex output connector, CH1/CH2, makes it easy to do sensor configurations without any bypasses or disconnections.

• RS422 to RS232/USB converter
• RS232 to USB converter
• Baudrate up to 230 kbps
• Duplex port
• ESD protected inputs
• 1000V magnetic isolation
• Small size
