Abstract: Provided herein are various enhanced systems, apparatuses, and techniques for optical communication among a constellation of satellites. One example includes establishing an initial cross-connect configuration comprising optical communication links among a constellation of satellites. In the initial cross-connect configuration, the satellites can optically communicate with both adjacently positioned and non-adjacently positioned satellites in the constellation. The satellites obtain angular states of the optical communication links resultant from orbital motion of the satellites. When angular states of a portion of the optical communication links reach an exclusion range, the satellites establish a subsequent cross-connect configuration to avoid optically communicating within the exclusion range.

Abstract: A modular spacecraft is provided. The modular spacecraft includes a bus module and a payload module. The bus module provides additional thermal radiative capacity for the payload module by including a bus-panel payload thermal zone that couples operational components of the payload module to a radiator panel in the bus module. The bus module also includes its own operational components that are thermally coupled to the radiator panel but that are thermally isolated from the payload module and the bus-panel payload thermal zone.

Abstract: Systems and methods of the present disclosure can be utilized to provide an improved propulsion system that uses multiple high efficiency engines to provide fault-tolerant and scalable high thrust for orbit transfer and maneuvering over life. An exemplary spacecraft includes a base panel, a cylindrical core member mounted to the base panel, multiple DV thrusters mounted within the cylindrical core member, and multiple reaction engine assemblies mounted to the base panel outside the cylindrical core member. Each of the DV thrusters has a thrust level that is greater than a thrust level of each of the reaction engine assemblies. The multiple DV thrusters are operated for velocity control, with attitude control being performed by off-pulsing at least one of the multiple DV thrusters.
