<u>Purpose</u>. This instruction provides high-level operational policy, guidance, and procedures for narrowband¹ satellite communications (SATCOM) user requirements and for Joint Interoperability Test Command (JITC) system standards conformance test certification. <br><u>Applicability</u>.

Included in this definition are the space, control, and terminal segments, as well as accesses used to integrate UHF SATCOM into the Global Information Grid (GIG). Unless stated specifically, the term "narrowband" used throughout the remainder of this instruction is a reference to narrowband SATCOM.
