By harnessing data handling lessons learned from the International Space Station, Gateway has adopted a highly reliable, deterministic, and redundant three-plane Time-Triggered Ethernet network implementation that is capable of handling three distinct types of traffic: Time-Triggered (TT), Rate Constrained (RC) and Best Effort (BE). This paper will offer an overview of the operational capabilities of the Gateway Network defined in the Network Concept of Operations, focusing on the initial architecture of the Gateway Spacecraft Inter-Element Network. The initial Gateway modules include Habitation, Power & Propulsion, Logistics, Human Lunar Lander, and Orion Crew Capsule. The Gateway Inter-Element Network Concept of Operations is a source for the network functions, which in turn inform the design, development, implementation, testing, and verification of the spacecraft hardware. End system hardware on the network includes, but is not limited to, a mobile robotic arm, internal and external cameras, flight control hardware, environmental control systems, power and propulsion systems, critical alarms, telemetry, and payloads, in addition to any hardware present on a visiting vehicle or lunar exploration vehicle. This paper will also provide an overview of how the design and operations of the Gateway Avionics network are defined by the Gateway Program design and safety requirements. Implementation of avionics and command and data handling strategy will provide the Gateway program with reliable infrastructures that allow operational options for both human control while occupied, and highly autonomous control during periods of vacancy. The Gateway Avionics network architecture will be able to handle seamless in-flight reconfigurations and expansion as new modules and the capability to interface with additional visiting vehicles are added.
