This activity shall develop a Payload Interface Data Handling Unit (PIDHU) for SWE hosted payloads which shall provide power supplies at various voltages required by space weather/environment instruments limiting the mass required for individual instrument voltage transformers. The PIDHU shall receive data streams from instruments through various protocols including UART (RS-422/485), SpaceWire, MIL-STD-1553 and CAN Bus and provide data though a single data interface adaptable to hosting spacecraft requirements.

The previous GSTP de-risk activity has demonstrated the manufacturing feasibility of an inner nozzle shell. A full size inner part has been produced in 253MA Stainless Steel and a subscale part in Carpenter 21-6-9 Stainless Steel.

The main benefits of this manufacturing process are a potential recurring cost and lead time reduction for the nozzle extension (since the number of parts, welds and other manufacturing steps required for the nozzle manufacturing would significantly decrease).

The advent of Optical Frequency Combs (OFC) has provided an enabling system for high-resolution spectroscopy, timing, ranging, metrology, clocks and the generation of ultra-pure frequencies in both the visible and rf spectral regions while being simultaneously phase coherent in both domains, enabling a direct rf-optical link.

This activity will focus on the development of a photonic integrated circuit (PIC) based version of the de-risked novel light source. As with the bench-top version, the chip consists of three stages and operates as follows. Stage one produces an optical comb centred on 795nm and with a wavelength spacing of 6.835 GHz. In stage two, the demultiplexer stage, this comb is split into two equal paths each of which lead to an injection locked laser. The two injection locked lasers are tuned to select a pair of adjacent wavelengths from the comb.

In the frame of past research activity focused on reviewing numerical time integration schemes for solving complex deployable space system such as Large Deployable Reflector and P-band FLATS antenna, two main limitations were clearly identified:
 
  • The first limitation is on the modelling of discontinuities (such latches, brakes,...). The current representation of these elements is not optimized with severe consequences on solution convergence and robustness.

    The continuously increasing amount of long-term and of historic data in EO facilities in the form of online datasets and archives makes it necessary to address technologies for the long-term management of these data sets, including their consolidation, preservation, and continuation across multiple missions. The management of long EO data time series of continuing or historic missions, with more than 20 years of data available already today, requires technical solutions and technologies which differ considerably from the ones exploited by existing systems.
