Designers will claim by default that their designs are modular. But experience shows they tend to create largely integral architectures, often under the pretense of vertical integration and in-house know-how protection, incurring in troubling non-recurring costs, creating high-switch barriers, and more importantly, delaying time to orbit (and to market). Reality is that both vertical integration and IP protection can be achieved using modular open architectures. The important bit is to identify which blocks of the architecture are worth reinventing from scratch. In NewSpace, core differentiating technologies tend to be on the payloads and sensors. Hence, the spacecraft bus architecture can be commoditized by choosing standard backplane-based form factors, high-speed serial communication, and configurable interconnect fabrics.
