Accurate time tagging for improved survey results

Synchronised interface unit – 1U rack-mounted PC with 24-port RS-232 interface.

When time accuracy is of pivotal importance to your survey operation, the ATTU offers you a simple way of taking the time-tagging feature of EIVA's NaviSuite software to the highest level.

Maintaining timestamps in distributed data flows

On ships with a distributed data flow, use EIVA’s ATTU interfaced together with a regular LAN – and it will ensure you never lose time-tagging information during distribution. The ATTU can be applied in any survey set-up that includes EIVA’s navigation and data acquisition software solutions, such as NaviSuite Kuda Core or NaviPac and NaviScan

Note: This ATTU is used on surface vessels, however it can be adapted for subsea units upon request.

    When time accuracy is of pivotal importance to your survey operation, the EIVA ATTU time-tagging unit offers you a simple way of taking the time-tagging feature of EIVA's software to the highest level.

    ATTU can be applied in any survey set-up that includes EIVA NaviPac and NaviScan navigation and data acquisition software solutions.

    Accuracy better than 50 µSec

    Knowing the when and where of your sensor data is an essential element when you want optimum accuracy and high-quality data of your survey operations. ATTU ensures a time-tagging accuracy that is better than 50 µSec. This is far superior to what can be obtained through use of the standard clock of an ordinary PC.

    Setting survey sail quickly through easy configuration

    The rack-mounted ATTU unit enables plug’n’play installation into existing solutions – you simply connect the sensors and configure the unit in the intuitive web interface.

    The ATTU has a multiplexer which converts the serial sensor feeds into a single UDP/IP feed wrapped in the same time format. This, together with the fact that ATTU allows for distributed interfacing through optional location of the ATTU rack unit on the vessel, eliminates complex cabling.

    Configurable with non-EIVA software applications

    Should you want to use the ATTU with your own software applications, we also licence out the ATTU protocols and formats on request.

    Possible to fit as OEM equipment

    The ATTU can be fitted as an OEM product. This is done by integrating the ATTU in a subsea housing, which comprises of electronics, firmware, a number of serial ports and a multiplexer, into your own subsea unit. This is for example an ideal solution for ROVs with multiple sensors, as the multiplexer converts data from serial to IP.
