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.

“…Communication technologies for onboard communication networks are rapidly developing. New standards and protocols, new principles and mechanisms of data transmission, new equipment that implement these mechanisms and protocols appear [1,2]. The MIL-STD 1553 [3] bus has been used for data exchange in onboard systems since the 1970s, but the rapidly growing requirements for the functionality of spacecraft make its further use impossible.…”

Introduction: New technologies are replacing the onboard space networks based on bus topologies. One of these technologies is SpaceWire. New communication protocols are being developed, expanding SpaceWire functionality. The protocol developers should provide all the required technical characteristics for data transmission and processing. Purpose: Analysis of the existing requirements for communication protocols, and development of consolidated set of requirements that will take into account the modern requests of the space industry. Results: The analysis of the existing demands on communication protocols resulted in a set of consolidated requirements for the physical-network layers’ protocols and the transport layer protocols. The requirements cover the speed, latencies, transmission distance, transmitted information amount, fault detection functionality, time synchronization between the devices, quality of service, main user data types, and data transfer modes at the transport level. The existing SpaceWire protocols are defined as a special class of protocols, possessing unique characteristics. Practical relevance: The performed analysis can simplify the implementation of new onboard communication protocols and provide a required level of technique for new generation spacecraft.

The advent of powerful edge devices and AI algorithms has already revolutionized many terrestrial applications; however, for both technical and historical reasons, the space industry is still striving to adopt these key enabling technologies in new mission concepts. In this context, the current work evaluates an heterogeneous multi-core system-on-chip processor for use on-board future spacecraft to support novel, computationally demanding digital signal processors and AI functionalities. Given the importance of low power consumption in satellites, we consider the Intel Movidius Myriad2 system-on-chip and focus on SW development and performance aspects. We design a methodology and framework to accommodate efficient partitioning, mapping, parallelization, code optimization, and tuning of complex algorithms. Furthermore, we propose an avionics architecture combining this commercial off-the-shelf chip with a field programmable gate array device to facilitate, among others, interfacing with traditional space instruments via SpaceWire transcoding. We prototype our architecture in the lab targeting vision-based navigation tasks. We implement a representative computer vision pipeline to track the 6D pose of ENVISAT using megapixel images during hypothetical spacecraft proximity operations. Overall, we achieve 2.6 to 4.9 FPS with only 0.8 to 1.1 W on Myriad2 , i.e., 10-fold acceleration versus modern rad-hard processors. Based on the results, we assess various benefits of utilizing Myriad2 instead of conventional field programmable gate arrays and CPUs.
