Evaluating Capabilities of the GigaSpaceWire Interface Implemented on the Modern Domestic Element Base

Abstract

Currently, space industry uses a variety of the specialized data transmission interfaces designed to solve specific problems taking into account the element base capabilities. This situation leads to the need to use various interface converters in pairing the dissimilar data transmission lines. As a result, separate characteristics of the systems being created are reduced, and their structural complexity and processing time increase. Thus, there appears a need to apply a unified high-speed network interface as part of the onboard equipment and in the ground product processing. Taking into account the above, network interfaces of the SpaceWire family look the most promising. In connection with the domestic standard coming in force, the paper considers the high-speed GigaSpaceWire interface, i.e., an extension of the SpaceWire interface with the improved characteristics, implemented in the latest domestic element base. In order to assess a possibility of using the GigaSpaceWire as a reliable data transmission interface, a workstation was created, software was developed, and a series of experiments were conducted. It was established that actual characteristics of the GigaSpaceWire controller were not fully corresponding to those declared in the standard, and practical application of the corresponding element base was associated with a number of features
