Ku Band Generic Flexible Converter for Flexible Innovative Payloads
27 January 2015
Enhancing capacity and flexibility is one of the major challenges for new-generation Ku-band payloads. One of the main axis is the introduction of flexibility within conventional payload with the qualification of Ku-band flexible frequency converters.
REGYS 20
12 January 2015
The objective of this activity was to increase the robustness and speed of the EEE parts procurement and testing of the Regys20 gyrometer for space applications. This comprised of 2 main work packages: i) EEE parts procurement transfer from Syderal to Sagem, through a CPPA (centralized parts procurement agent), and ii) the robustification of the testing process. This latter WP consists of 4 main points of improvement: - 2 additional two-axes rate tables were qualified to avoid a bottleneck in the AIT process - The EEPROM management process was enhanced with multiple checks to avoid human operator error and detect read/write errors - The calibration process was robustified to automatically detect out-of-family-behaviour - The test sequence was automated to allow weekend and night-time automated testing and save considerable time. The combination of the above 2 WPs has considerably increased the competitiveness of the Regys20 and increased the robustness of the AIT process.
MEMS-based satellite propellant gauging system
12 January 2015
NanoSpace has under this contract continued to develop a gauging system to predict the residual propellant on-board satellites in orbit. The target market is medium and large satellites in Geo-synchronous orbits. The main value lies in capability to predict end-of-life with high accuracy – for a typical satellite down to a few weeks. A first engineering model has been designed, built, and tested together with propellant tanks up to 368 litres within this contract. Test results have demonstrated accuracies between 0.07% to 0.35%, depending of amount of gas injected. Test results compared with EcosimPro-simulations shows excellent agreement.
Digital test bench for fast testing of complex Payloads
18 December 2014
The objective of the study is to develop and validate a digital test bench for use during AIT and IOT for all C-band to Ku-band payloads, exploiting innovative and rapid RF test techniques to significantly reduce the overall test schedule. Furthermore extension to Ka-band payloads and RF interface using optical fiber are designed.
Ku-Band High-Power Reconfigurable Broadcast Antenna
17 December 2014
In the frame of this activity an innovative Ku-band high power reconfigurable multibeam broadcast antenna has been designed, with the development and test of a demonstrator model. The most promising payload solutions suitable to support the present application in terms of both antenna configuration and front-end architecture have been identified and investigated in detail. This extended trade-off activity led to an innovative antenna solution consisting of a Confocal antenna configuration fed by an aperiodic feed array. The designed Confocal antenna architecture, associated with sparse/aperiodic array feeding system, creates an innovative approach capable to fulfill the reconfigurable regional coverage mission in Ku-band, with full array operation and then full reconfiguration capability, full power allocation flexibility and graceful degradation, minimizing the number of controls.
