Space Wire (SpW) technology is a data-handling spacecraft network for that connects on-board sub-systems. The European Space Agency (ESA) is encouraging research in the area of wireless intra-spacecraft communications in order to develop a solution complementary to the wired infrastructure. The HiSAT project aims to provide a high-throughput end-to-end intra-spacecraft wireless solution. This paper presents a TCP/IP-to-SpW converter employing a ZCU102 development board on which the Lightweight IP networking stack and SpW IP core were integrated. The validation of the proposed solution consists in investigating the SpW data link initialization, data integrity and data rate of the implemented design.
