“…The WSN prototype was tested on the Venus Express mock‐up at the European Space Research and Technology Centre premises in Noordwijk, Netherlands, on the Sentinel‐3 mock‐up at the CDS premises in Cluj‐Napoca, Romania, and in the anechoic chamber at the “Gheorghe Asachi” Technical University of Iasi, Romania. A packet success rate analysis shows that the proposed solution provides high performance for low power UWB transmissions in both low gigahertz band (channels 1 to 4) and the high gigahertz band (channels 5 and 7) …”

“…In this context, the scope of this paper is to present the prototyping of an intra‐spacecraft UWB wireless solution that meets the system requirements of the Euglena and Combined Regenerative Organic Food Production in Space (Eu:CROPIS) mission . Moreover, the solution is validated for real traffic generated by on‐board and payload instrumentation, raising the technical readiness level (TRL) from the proof‐of‐concept level (TRL3) reached in WiSAT‐1() and Wireless Compose() research projects, to the functional verification level in a laboratory environment (TRL4).…”

Summary This paper presents the design, testing, and validation of a ultra‐wideband (UWB) wireless solution to replace wired intra‐spacecraft communications with wireless communications. The system requirements are provided in the framework of the Eu:CROPIS mission and the wired intra‐spacecraft communication system is replaced with a two‐segment wireless network. As such, distinct sets of UWB gateways and nodes are prototyped to interface with the on‐board entities and properly handle the data transmission in the resulting spacecraft and payload wireless networks. To accomplish these tasks, a custom radio module integrated into the prototypes was designed to provide the appropriate UWB RF front‐end and run a custom‐built communication stack. The viability of the solution was tested in laboratory conditions. For the test scenarios, sensor data are acquired in the payload network and forwarded as SpaceWire packets over the spacecraft network. Experimental test results indicate the suitability of the proposed solution in terms of delay and data integrity for implementing intra‐spacecraft wireless communications.

“…[2][3][4] Multiple input multiple output (MIMO) technology and ultra-wide band (UWB) system are two possible solutions because of their advantages of large capacity. [5][6][7][8][9][10][11][12] In the MIMO systems, beamforming is a widely accepted technique that utilizes multiple antennas to form a fan beam. [13][14][15][16] However, the beamforming scheme may not work appropriately in the spacecraft cabins with richscattering environments because the line-of-sight (LOS) link may be blocked by impenetrable objects or distorted by the metal walls.…”

A wireless communication scheme named point focusing (PF) wireless communication is proposed for intra-spacecraft wireless transmission. In this scheme, a set of point focusing fields (PFFs) generated by the time reversal (TR) based field shaping method are employed to carry the binary bits. Based on the orthogonality of the non-overlapped focal points of the PFFs, the same spectrum can be spatially reused. The point-to-point spacing between PFFs is half a wavelength, that is, a distance at Rayleigh diffraction limit, which can maximize the spectrum reutilization efficiency in a bounded spatial region. A closed metal cavity is employed to numerically and experimentally demonstrate the performance of the PFFs based wireless communications.

SummaryThe scope of this paper is to present the proof‐of‐concept and functional verification of a Wireless‐SpaceWire bridge (High‐Throughput Wireless‐SpaceWire Bridge for Intra‐Satellite Transmissions [HiSAT] bridge) designed to replace the wired SpaceWire (SpW) connections for intraspacecraft communications. To provide proper data handling and conversion, the proposed solution implements two main components: (1) the SpW Converter, which provides the SpW interface, and (2) the Wireless Converter, which provides the multiantenna radio frequency (RF) front‐end. High‐end research infrastructure is used in the solution implementation. STAR‐Dundee SpW products emulate real spacecraft instrumentation and implement the SpW links and interfaces. Xilinx FPGA ZCU102 boards are used for the implementation of the hardware/software communication stack of the SpW Converter. A comprehensive National Instruments USRP Software Defined Radio platform is used to implement the Wireless Converter. End‐to‐end laboratory tests are run to evaluate the performance of the proposed solution in terms of average end‐to‐end delay, average data rate, and packet success rate and to assess the technology readiness. The results demonstrate that the HiSAT bridge is TRL4 and that the technological approach (i.e., using FPGAs and OFDM transmissions) can successfully replace an on‐board intraspacecraft SpW link.
