    ST Engineering, Sumitomo Corp. and Skyports have formed a consortium to provide unmanned aircraft system (UAS) services for heavy-lift shore-to-ship parcel delivery in Singapore, home to one of the biggest ports in the world

    Each consortium member will use its respective operational and technological capabilities to expand the use of UAS for deliveries of maritime essentials to anchored vessels. During a nine-month pilot program, the consortium will engage key customers for maritime UAS deliveries, with the goal of establishing a delivery network capable of carrying parcel payloads of 10 kg.

    ST Engineering will provide the UAS technology using its end-to-end solution DroNet. Skyports will jointly conduct the beyond-visual-line-of-sight (BVLOS) flight operations with ST Engineering. Sumitomo Corporation will provide go-to-market support, including its own fleet of vessels.

    As an unmanned systems participant in Singapore, ST Engineering has been testing and developing autonomous solutions to enable BVLOS UAS operations for shore-to-ship delivery in close collaboration with regulators and industry partners.

    Through funding support from the Civil Aviation Authority of Singapore (CAAS), the group completed the initial development of a UAS for shore-to-ship parcel delivery based on the DroNet solution.

    Compared to the traditional form of delivery by boats, UAS operations can significantly slash response time and speed up turnaround for shore-to-ship delivery, in addition to reducing logistics costs. Replacing launch-boat delivery with a UAS service also helps reduce carbon emissions and contribute to the maritime industry’s overall efforts to operate sustainably.

  • AgilLOC antenna element combats GNSS jamming at sea

    With the proliferation of jamming devices readily available, maritime vessels need to be situationally aware of GNSS interference and disruption. The threat of GNSS jamming is made even more critical in situations that require navigation through narrow straits under poor visibility, with no sea lane markers in sight.

    Case in point being the British-flagged oil tanker Stena Impero, which was seized by Iran’s Revolutionary Guards while sailing through the Strait of Hormuz. Iranian Islamic Revolutionary Guard Corps stated that Stena Impero had taken a wrong route when entering the Strait of Hormuz.

    This happened during a time when an advisory warning by the U.S Maritime Administration had already been released, stating that vessels operating in the Persian Gulf, Strait of Hormuz and Gulf of Oman may encounter GPS interference, bridge-to-bridge communications spoofing or other communications jamming with little to no warning.

    This episode could have been avoided if better awareness of the navigation system was employed.

    Jamming protection at sea. ST Engineering has developed AgilLOC Antenna Element Compact (AEC), which provides GNSS protection against three simultaneous jamming/interference sources with its adaptive nulling algorithm for the maritime sector, ensuring continuous GNSS protection to connected systems.

    AgilLOC AEC was designed for easy integration with new or existing legacy systems that required uninterrupted GNSS reception. Despite its lightweight and compact design, AgilLOC AEC provides a robust response to narrow and wideband interference, the company said.

    When disruption happens. In a disruption, the crew onboard can only rely on radar or cross bearings using compass, terrestrial radio navigation or even sextants.

    The loss of GNSS input to the ship’s surface search radar, gyro units and electronic chart display and information system (ECDIS) will result in a lack of GNSS data for position fixing, radar over ground speed inputs, gyro speed input as well as the loss of collision avoidance capabilities on the ECDIS radar display. It is imperative that all ship’s crew are aware of the status of their GNSS reception.

    Many GNSS receivers currently installed onboard vessels do not provide for jamming monitoring or mitigation. Deliberate or unintentional GNSS inference are becoming more prevalent, increasing the risk of receivers being overwhelmed by elevated levels of interferences.

    Satellite navigation is essential for all maritime applications under all weather conditions. The AgilLOC AEC protects the GNSS signals for a smooth navigation and precision landing alongside with other navigational systems.
