Spacecraft Command and Data Handling

Satellite missions use C&DH software for bus operation. SDL’s bus control software implements a Modular Open System Architecture (MOSA), which enables a high level of reuse and adaptability to meet a broad range of satellite mission requirements. Modularization of bus functionality enables developers to integrate mission specific hardware and payloads with few modifications, significantly reducing the development, integration, and testing of spacecraft systems.
