WINK Satellite

Context | Space Rider

WINK, is a payload funded with the PRIN 2022 call, born from the close collaboration between GSSI [Gran Sasso Science Institute], UNINA [Federico II, University of Naples] and INFN [National Institute of Nuclear Physics]. In particular, the electronic system is designed by the INFN-Section of Naples while the mechanical one by UNINA, in collaboration with Sòphia High Tech.

This scientific payload was created as a prototype of a larger detector and will be composed of 3 of the 112 pixels that will make up the complete detector, with the primary purpose of testing the detection strategy. WINK represents a technological forerunner for future gamma ray detection experiments, under the aegis of ASI [Italian Space Agency] and on board the inaugural flight of Space Rider by ESA [European Space Agency].

Space Rider Program

WINK will operate in orbit for two months, then return to Earth and will test a new technology in a space environment to observe the gamma ray sky by measuring Gamma Ray Burst (GRB), in the energy range of interest 10 keV ÷ 30 MeV. The WINK payload mission will be divided into two main phases:

  • Space observation mode: the detector points towards the deep sky. In this phase, the continuous characterization of cosmic rays in orbit and the search for GRBs will be carried out. The minimum duration required for this phase is at least 5 weeks.
  • Earth observation mode: The detector points towards the Earth. In this phase, Earth observation will be carried out (e.g. gamma ray flashes). The minimum duration required is 1 week.

Targets | Wink Satellite

WINK è utilizzato per applicazioni di Ricerca e Sviluppo nell’ambito delle Scienze Fisiche ed è classificato come Fixed Payload (rimanendo fissato all’MPCB di Space Rider MPCB durante la missione), e Direct Exposure Required (DER) Payload richiedendo, per la natura dell’esperimento da eseguire, un’esposizione diretta e continua all’ambiente spaziale.

WINK Satellite-concept design

The activities, carried out by SOPHIA, involve both the Design, Optimization, Manufacturing and Qualification phases of the entire mechanical architecture of WINK. In particular, the Company is responsible for the following phases:

  1. 3D CAD design and optimization of the structure and arrangement of the crystals, to guarantee coupling methods and stability within the honeycomb structure;
  2. FE model creation of the assembly in accordance with ECSS-ESA;
  3. Numerical Analysis for the load envelope of the VEGA-C space launcher, necessary for the sizing of the structures and the definition of the materials and heat and/or surface treatments most suitable for the application;
  4. Definition of the assembly/assembly sequence of the crystals and alveolar structures;
  5. Creation of productive Drawing Sets (2D CAD) (DWG and BOM, Bill of Material);
  6. Procurement of Materials and Standards;
  7. Manufacturing (Part Program and CAM Creation) and Assembly of both the Qualification Prototype [QM] and Flight Model [FM];
  8. Dimensional control and validation;
  9. Development of mechanical interfaces for ECSS-ESA Qualification Tests
