Real-time Software

Triggerfish

Triggerfish is a scalable, distributed, navigation, synchronization and management suite designed for marine geophysical survey operations. The system runs on robust industrial Microsoft Windows platforms (LTSC) and despite comprehensive functionality is simple and intuitive to configure and operate. The system interfaces with an extensive range of positioning sensors, recording and source control systems. The system supports the EPSG geodetic database and fully compliant IOGP Px11 formats. Common sensor fomrats are supported and new interfaces will be added on request. For multi-vessel operations, Triggerfish links remote vessels/stations via radio networks. GNSS disciplined, bus level timing components provide source and recorder event triggers and timestamps to microsecond accuracy. The core software components allow support for all types of marine seismic operations, thus making Triggerfish an ideal choice for single, multi-function vessels and flexible crew operations. The software is built on proprietary client/server architecture and can be distributed across a wide-area network - components are available to transfer data via internet to cloud storage or shore facilities.

Processing and QC Software

GeoMetis Shotpoint

Geometis Shotpoint - a software tool for quality control analysis and data processing of positioning data on Towed Streamer and OBS or TZ seismic surveys. Using an interactive control system the user can define and step through a host of data analysis and reprocessing modules depending on the client requirements. Geometis Shotpoint, provides a series of tools to assess data quality prior to reprocessing so the actual recorded data is analysed.

  • Providing a lightweight and portable system with a small physical footprint.
  • Software is intuitive, easy to learn and use and provides rapid data analysis.
  • Convenient Web based access and email support.
  • Interactive multi-screen processing for flexibility and user control.
  • Data format checking and verification (SPS and UKOOA/OGP P2/P1format).
  • Receiver Positioning (First Breaks and acoustics).
  • Statistical, graphical and textual displays.
  • User defined process/QC reporting.
  • Easily check SPS files for compliance.
  • Analysis of SPS data.
  • Graphical and text displays.
  • Software is installed and configured by the user and runs on notebook or desktop computers.
  • Runs on all Microsoft Windows platforms.

    • Shotpoint is owned and distributed by NorthStar Geo Limited. InProspect have an agreement to act as a sale and rental agent on their behalf.

    Binning and coverage analysis

    Coverpoint

    CoverPoint is an advanced system for analysing marine survey coverage. Data Entry is designed to be simple and efficient. Entered Data is shown on a map to aid the setup process, and the system also allows for the mapping of navigation data to aid data analysis. The CoverPoint software can bin data using full offset and azimuth-based fold generation, or by a simpler hits-per-bin coverage computation. Coverage can be generated from two distinct sets of data and compared against each other. Data can be colour coded and presented in a number of ways to aid viewing. The resulting coverage data can be exported as a geo-referenced image file for use in GIS systems. Coverpoint is fully integrated with Triggerfish software.

  • Coverage and binning of marine surveys.
  • Easy to setup, configure and use.
  • Graphical displays to aid configuration and setup.
  • Generation of reports and GIS outputs.
  • Powerful information displays.

    • CoverPoint is owned and distributed by Mid Point Geo Limited. InProspect have an agreement to act as a sale and rental agent on their behalf.

    Hardware Systems

    Timing Systems

    The Timing Interface Unit (TIU) and TSYNC PCIe card were introduced in 2018 and replace the legacy GTU (Gravel Trigger Unit). The system consists of a PCIe interface board that is installed in the Triggerfish server PC and the TIU, 1U enclosure, which contains opto-isolator circuits, voltage selection and switching for high-low impedance outputs - high impedance outputs are designed for direct connection to seismic recorder auxilliary channels. Multiple units can be installed to increase the number of triggers available. All timing functions are retained within the TSYNC system and events are requested via the timing card API. This ensures that timestamping and events are controlled not within software loops in the Triggerfish code but at the hardware level within the timing card itself, this removes ambiguity associated with systems which use 1PPS epoch within application software.

  • 1U rack-mount enclosure + PCIe card.
  • GNSS disciplined OCXO or TCXO options available.
  • 4 Output triggers, microsecond accuracy, high/low impedance, 1.2V/5V/12V.
  • 4 Input triggers, 3V-12V, timestamping to microsecond precision.
  • 1PPS & IRIG outputs.
  • UTC, IAT or GPS time references supported.
  • Multi-vessel synchronisation radio TDM (time division multiplex) control.


    • Computer Systems

    InProspect can supply custom computer and networking hardware and serial and network server devices to run Triggerfish systems. All form-factors - rackmount (1U and upwards), desktop and laptop computers can be delivered. InProspect Limited is a Microsoft Partner and re-seller licensed to supply MS Windows operating system software. MS Windows Enterprise LTSC versions, which are suited for continuous “always on” applications, are provided with Triggerfish hardware systems.


    Radio Systems

    InProspect can supply and advise on a range of radio products to suit specific operational needs and comply with local regulations. Where necessary, signal boosters, antenna towers/masts and specialist antennae can be provided. InProspect are able to provide radio transmission path analysis to assist in system design.
