SIAP (Single Integrated Air Picture) A shared, single graphical representation of the battlespace

Under development by the Joint SIAP System Engineering Organization (JSSEO), Arlington, Va., the ambitious SIAP (Single Integrated Air Picture) will allow U.S. military service personnel and allies to share a single graphical representation of the battlespace. This will be accomplished using data generated by multiple surface and air sensors and broadcast via a sophisticated logistical information distribution system. Now, JSSEO and NAVSEA (Naval Sea Systems Command) are designing SIAP to integrate with naval weapons. At build-out, the SIAP and will help users make better, more informed decisions by linking military forces and their tactical situations.

The critical nature of the SIAP necessitated the Navy to select an operating system featuring hard-real-time deterministic performance. It required an environment that would provide reliability, maintainability and availability, along with the interoperability of truly open systems code. POSIX® conformance was crucial; in fact, to support system interoperability and software reuse, all Navy OA systems are mandated to employ a POSIX-conformant operating system or a Linux®-based, open-systems approach. The only certified POSIX-conformant RTOS, LynxOS® was the natural choice and the Navy hasn't looked back since.
