The DLR developed the open source software framework RCE to support collaborative and distributed work in shipyard industry. From a technology side of view from shipbuilding field has many requirements common with aerospace projects. Accordingly, become basis for further projects within DLR. Over last years usage subset frequently used components could be derived are provided by framework. In particular, workflow engine, allowing integration different domain-specific tools local remote...
Today, phase A studies of future space systems are often conducted in special design facilities such as the Concurrent Engineering Facility at German Aerospace Center (DLR). Within these facilities, performed following a defined process making use data model for information exchange. Quite it remains unclear what exactly is and how implemented applied. Nowadays, usually software using formal specification describing its capabilities within so-called meta-model. This meta-model, referred...
Recently, promising progress has been made by open-source vision-language models (VLMs) in bringing their capabilities closer to those of proprietary frontier models. However, most only publish final model weights, leaving the critical details data strategies and implementation largely opaque. In this work, we address VLM post-training from a data-centric perspective, showing key role strategy developing VLMs. By studying building our scratch, share detailed insights into development...
Optical Character Recognition (OCR) technology is widely used to extract text from images of documents, facilitating efficient digitization and data retrieval. However, merely extracting insufficient when dealing with complex documents. Fully comprehending such documents requires an understanding their structure -- including formatting, formulas, tables, the reading order multiple blocks columns across pages as well semantic information for detecting elements like footnotes image captions....
The continuous monitoring of radioactivity in a cabled subsea network the North Sea Observatory was performed to test performance medium-resolution underwater spectrometer, as well identify and assess potential anthropogenic and/or natural hazards. effectiveness tested together with operability sensor, quantification methods were optimized type activity concentration radionuclides seawater. In frame RADCONNECT project, system named GeoMAREA integrated into an existing ocean observatory...
Despite popular belief, space missions are not always one-of-a-kind, but frequently benefiting from explicit or implicit reuse of different types. The Venus Express mission is one example cost savings by reusing existing hardware in a new context. Other examples based on the platform approach, popular, for example, geostationary telecommunication satellites, which benefits pre-planned and its application to family with commonality. While latter handled more strategically, promising gain...
This paper presents how a continuous mission verification process similar than in software engineering can be applied early spacecraft design and Concurrent Engineering.Following the Model-based Systems Engineering paradigm, all engineers contribute to one single centralized data model of system.The is enriched with some extra information create an executable representation its mission.That scenario allows for verifications against requirements that have been formalized using appropriate...
Planning a spacecraft requires the expert knowledge from diverse disciplines, such as propulsion or structure. Reliable communication between experts is crucial, individual requirements of satellite's various subsystems heavily depend on each other. Today, early mission design sessions are often held in specially designed rooms, so-called concurrent engineering facilities. Here, come together and directly discuss with other shared place, enabling them to find common ground much quicker....
In the early design phase of a spacecraft, various aspects system under development are described and modeled using parameters such as masses, power consumption or data rates. particular special since their values can change depending on spacecrafts operational mode. These mode-dependent be easily verified to static requirements like maximumdata rate. Such quick verifications allow engineers check after every they apply. contrast, concerning mission lifetime amount downlinked during whole...
In this paper we propose an integrated immersive augmented reality solution for a software tool supporting spacecraft design and verification. The process relies on expertise in many domains, such as thermal structural engineering. various subsystems of are highly interdependent have differing requirements constraints. context, interactive visualizations play important role making expert knowledge accessible. Recent display technologies offer new ways presenting interacting with...
Guaranteeing safety and correctness is one of the main objectives during development space systems. This a challenging task, since many different engineering disciplines are involved in constituent parts spacecraft highly interconnected interdependent. Increasingly, formal methods such as model checking applied to verify safety-critical designs also implementation, they may prove absence design errors. Generally, major challenge for adopting into process its scalability. Usually, whole state...
Designing a spacecraft involves many experts from different domains. In the early design phases they are brought together to discuss in short period of time. The elements and building blocks individual engineers want use stored described shared system model provided by software framework. A lot features like masses or dimensions using parameters. Due various domains preference, units used, leading mistakes, distraction misunderstandings caused unit conversions. Our paper describes pragmatic...
