The vision of hardware interoperability at the tactical edge, from air platforms to ground vehicles to base stations, is now being realized. Because MOSA [modular open systems approach] is an approach and not itself a standard, solutions that support this vision can be achieved through many different means as long as interfaces and communications protocols are based on open standards. There remains a key area to address, though, to achieve seamless interoperability between heterogeneous systems. Consider, for example, the Sensor Open Systems Architecture (SOSA) Technical Standard: While most aspects of sensor processing system architectures are well-defined within SOSA, one area that has not been rigidly defined is the network configuration and operational environment of individual cards and modules.
