[Abstract]

Despite the transfer of many typical functionalities to very small satellites, precision attitude and orbit control capabilities are still a domain of conventional large satellites. UWE-4 has now demonstrated orbit control capabilities on board of a pico-satellite for the first time. The orbit altitude of UWE-4 was raised and lowered using the electric propulsion system NanoFEEP. An early detected collision danger enabled the execution of an avoidance maneuver in July 2020 to increase the distance of closest approach. This contribution describes the UWE-4 orbit control system and the related evaluations during operations.

[Abstract]

The term Industry 4.0 – manufacturing with exploitation of digital technologies – comprises several challenging topics, among others intuitive machine programming, advanced maintenance-enabling technologies as well as flexible logistics. This paper gives an overview on recent research and development of our institute (Zentrum für Telematik, ZfT) in this field, the results of which are combined in an Industry 4.0 demonstration factory for the assembly of small satellites systems. We present a total of six tools to be used in such advanced manufacturing systems and their individual advantages. Based on our experience with industrial project partners, customers and visitors of our demonstration factory as well as on the evaluations of the jurors of several awards, we give a qualitative estimate of the effort required to port the individual tools to new production environments. Finally, utilizing our in-house expertise in the New-Space and Industry-4.0 sectors, we give an insight into the benefits achievable using digital manufacturing for small satellite assembly.

CloudCT 3D volumetric tomography: considerations for imager preference, comparing visible light, short-wave infrared, and polarized imagers

[Abstract]

The CloudCT project is a mission that aims to demonstrate 3D volumetric scattering tomography of clouds. A formation of ten nanosatellites will simultaneously image cloud fields from multiple directions, at ≈20m nadir ground resolution. Based on this data, scattering tomography will seek the 3D volumetric distribution of cloud properties. We quantitatively compare visible polarized imagers to other imagers considered for the mission. We investigated specifically visible light and short-wave infra-red imagers. Each possibility was considered using Large Eddy Simulation clouds. Major consideration criteria are tomographic quality in the face of sensor and photon noise, calibration errors and stray light. We check the sensitivity to unknown stray light and uncertainty in gain calibration.
