The Integrated Test and Operations System (ITOS) is a generic system of software for controlling spacecraft and components of spacecraft during development, testing, and operation in orbit. The ITOS software is an inexpensive, portable, highly configurable system that runs under a variety of UNIX operating systems — including Solaris, FreeBSD, and Linux — on workstations or personal computers. The ITOS evolved from the ground support equipment built in 1990 to support integration and testing of SAMPEX, the first Small Explorer (SMEX) mission, and now is supporting SAMPEX and eleven other missions.
