The presented machinery concept CESA3R (Concept for Engineering free, Scalable, Advanced Automated Assembly system for Rapid ramp up) addresses today's challenges in production such as product variety and quantity variation by enhancing versatility. Central elements are function oriented standardized automation devices, which are technically featured with independent structure recognition and self-descriptive...
Magen- und Darmspiegelungen gehören nach Meinung der meisten Menschen nicht zu den wirklich angenehmen Erfahrungen, die man bei einem Arzt machen kann. Viele Patienten sehen sich großen psychischen und körperlichen Belastungen ausgesetzt. In der alltäglichen Praxis ist die psychologische Patientenvorbereitung aus Zeit- und Kostengründen überwiegend auf die intravenöse Gabe von pharmakologischen Mitteln...
The European Galileo system offers one dedicated signal that is superior to all other signals currently available in space, namely the broadband signal E5. This signal has a bandwidth of at least 51 MHz using an AltBOC modulation. It features a code range noise at centimeter level. Additionally, the impact of multipath effects on this signal is significantly lower compared to all other available GNSS...
Atmospheric sounding is an important scientific GNSS application: knowledge of the water vapor distribution is fundamental for weather and climate prediction and can be improved by ground GNSS networks and occultation measurements. All present global and regional navigation satellite systems use frequencies in L-band, which is getting more and more crowded. To generate a larger variety of frequency...
Atmospheric delays are contributors to the GNSS error budget in precise GNSS positioning that can reduce positioning accuracy considerably if not compensated appropriately. Both ionospheric and tropospheric delay corrections can be determined with help of reference stations in active GNSS networks. One approach to interpolate these error terms to the user’s location that is employed in Germany’s SAPOS...
This paper presents the design of a dichroic mirror, operating in the S-, X-, and Kaband, intended for a 35 m beam-waveguide antenna for deep space observation. The design of this structure is particularly challenging, due to the large dimensions and the tight electrical constraints. Three structures have been investigated, both from the electrical and the mechanical point of view, and the simulation...
