ArkEdge Space successfully launched its micro-satellite AE1a on March 30, marking a significant milestone in maritime digitalization. Following the establishment of communication via test radio signals, the satellite has entered its initial checkout phase. AE1a is designed to enhance vessel tracking and communication capabilities, utilizing ArkEdge Space’s standardized 6U satellite bus with a large-antenna configuration.
This technology demonstration satellite features a deployable antenna for VDES (VHF Data Exchange System) applications, aiming to validate and improve core technologies for VDES receivers. AE1a will work in conjunction with two other satellites, AE1d and AE3Va, which began operations in January and June 2025, respectively. Together, they form a three-satellite constellation aimed at demonstrating capabilities across extensive maritime areas.
AE3Va is currently collecting AIS signals from various sea regions, including the waters surrounding Japan and busy shipping lanes. The data gathered is being systematically verified and analyzed to ensure accuracy. Looking ahead, the project plans to transition from reception-focused demonstrations to two-way communications, allowing satellites to transmit operational information directly to vessels. This advancement will broaden the scope of VDES applications and facilitate concrete use-case validation within the maritime industry.
