    Your advantages with S.E.A. Datentechnik


    In addition to its own concepts and products, S.E.A. also offers customer-specific software and hardware solutions that are precisely agreed with the customer and adapted to the requirements.


    The continuous, systematic identification and analysis of the customer’s wishes, needs and expectations and their implementation in products, services and processes is our priority. We understand your requirements, advise and support you in every phase of the project.


    The maintenance of your software and hardware is important to us. But even more complex tasks are in good hands with us. We support you in all phases of your project. This also includes maintenance, service and repair, retrofit, obsolescence management. This is how we contribute to your success.

    Technical competence

    The capital of S.E.A. is an effective team with diverse engineering and scientific qualifications. The existing project experience and team quality is documented in an average company tenure of about 10 years.

    What our customers say

    The AWI research vessels have been equipped with a uniform DShip data acquisition and management system for several years. Our goal was to transfer this to the polar aircraft. To adapt to the much higher speed of an aircraft compared to a ship, the system had to become faster by a factor of 1000. Consequently, a pure software solution was no longer an option. The data acquisition part with the high-precision time synchronisation had to be transferred to newly developed hardware.

    The company S.E.A. understood how to take over this part and manage the necessary adaptation. It is in the nature of things that prototypes of this kind require additional modifications outside the specifications made at the beginning of the manufacturing process. S.E.A. accepted and implemented these in an extremely competent and uncomplicated manner. The entire manufacturing phase was cooperative and friendly. This also applies to the company’s ongoing service. In the meantime, the system has been expanded to include additional sensor technology for the two polar aircraft and a helicopter of the research icebreaker Polarstern has been equipped with the system.

  • The close cooperation with our partners S.E.A. and NI enables us to validate and verify our V2X devices corresponding to the expected high-quality level of Continental.
    The implementation of the V2X communication, RF-measurement and channel emulation for the 802.11p/DSRC and C-V2X on their software and hardware provide us access to the V2X technology and unique test features very early in the technology development.
    The SDR based communication implementation and cooperation with S.E.A. ensures that we are able to react to new requirements in short time.
    Overall the availability of V2X on the open NI platform enable us to be a leader in the V2X technology.

    Accelerating Vehicle Safety:
    Unleashing the Potential of V2X Automotive Connectivity

    Register here to view the webinar

    As the number of fatalities involving vehicles and vulnerable road users (VRUs) like pedestrians continues to rise, V2X plays a crucial role in improving vehicle safety; however, the implementation and testing of V2X technology pose significant challenges.

    During the webinar, you will gain invaluable insights into the ongoing efforts to go from standardization to validation of V2X technology:

    • Standardization initiatives involve key players such as automotive OEMs, Tier 1 suppliers, network operators, semiconductor companies, and device testers. These collaborative efforts aim to establish uniform protocols and guidelines for V2X implementation.
    • Validation is another critical aspect we will explore, focusing on 3GPP tests conducted at various levels. These tests encompass the physical level, V2X protocol level, and application level, including Day 1 Use Cases.

    Furthermore, we will discuss the additional benefits that 5G technology brings to V2X. The integration of 5G networks expands the capabilities and potential of V2X, enabling advanced applications and unlocking new opportunities for improved road safety. Join us to explore the cutting-edge advancements at S.E.A. in collaboration with NI, paving the path towards safer and more connected vehicles.
