    This paper presents a modular, ARINC 664 P5- and ARINC 853-compliant platform implemented via unified cabin hubs to facilitate the development of interoperable digital aircraft cabin solutions. To overcome the challenges of proprietary interfaces and system heterogeneity, the platform leverages the Cabin Secure Media-Independent Messaging (CSMIM) protocol, employing a data-driven publisher-subscriber architecture to enable secure and scalable communication in non-safety-critical aircraft cabin applications. Through the use of standardized data models and serialization, the platform integrates diverse supplier components, such as lighting, sensors, and galley equipment. Adopting a "Platform for X" approach, these hubs serve as versatile CSMIM network nodes capable of assuming various predefined functional roles via software reconfiguration. To support this agility, the platform leverages the Yocto Project build system to optimize lifecycle management and certification efforts while maintaining strict ARINC 853 compliance. The platform supports deployment within the Airline Information and Services Domain (AISD) and Passenger Information and Entertainment Services Domain (PIESD), utilizing a unidirectional interface from the Aircraft Control Domain (ACD) to enable extended In-Flight Entertainment (IFE) functions as motivated by ARINC 664 P5 Appendix H. Experimental validation involving physical hardware verification and GNS3 network emulation confirmed that Node identity is a configurable software property rather than a hardware constraint. The results demonstrate that secure, controlled cross-domain communication can be achieved via RabbitMQ federation without compromising the domain segregation required by ARINC 664 P5.

    Obtaining data from real-time location systems (RTLS) is critical in aviation for enhancing operational workflows, reliability, and passenger services. For example, applications such as wheelchair tracking, baggage management, seat-specific service delivery, and equipment monitoring require accurate and continuous positioning information within both aircraft cabins and airport terminals. Ultra-Wideband (UWB) technology, characterized by high accuracy for indoor localization, low latency and robustness against interference, can be employed to address these needs. This paper presents a platform architecture utilizing UWB localization that can be integrated into the cabin and can be certified in accordance with aviation regulations to support various applications on ground and in-flight. The architecture comprises modular edge cloud systems deployed across aircraft and ground environment, interconnected to enable efficient data exchange and hosting of location-based services. The onboard system integrates the ARINC 853 Cabin Secure Media-Independent Messaging (CSMIM) standard to ensure secure and standardized communication of localization data across the cabin network. The overall UWB RTLS is based on Kubernetes edge cloud platforms enabling the deployment and management of various location-based applications. Secure communication between aircraft and ground edge clouds is maintained through a virtual private network (VPN). Exemplary use cases include wheelchair tracking across airport and cabin environment and passenger-tailored onboard services such as meal ordering and serving tied to seat localization. The presented system and architecture support improvements in process efficiency and the delivery of personalized services, contributing to a unified, data-driven and smart aviation ecosystem.
