effectiveness of that exchanged information as required for mission accomplishment. Interoperability is more than just information exchange. It includes systems, processes, organizations, and missions over the life cycle and must be balanced with Information Assurance.”
The Project Management Office Aviation Systems (PMO AS) includes two product management organizations that support successful interoperability of Army Aviation systems: the Product Manager for Aviation Mission Equipment (PM AME) and the Product Directorate for Aviation Networks and Mission Planning (PD ANMP).
The PM AME was established as a cen- tralized management office to develop and field common avionics enablers, ensuring that shared solutions are used across the Army aviation fleet (see Figure 1). This commonality allows the Army aviation community to reduce risks and costs in researching and devel- oping minimal solutions and to realize substantial cost savings by leveraging purchase quantities.
PM AME, which is responsible for managing all communications, navi- gation, and surveillance capabilities required by Army aviation, currently procures, fields, and supports the following major systems:
• Doppler GPS Navigation System, a navigation capability with a 6-channel GPS receiver embedded in the signal data converter of the currently fielded Doppler navigation system.
• Embedded GPS Inertial Navigation, a tri-service, U.S. Air Force-led effort to provide extremely precise location information to the aircraft fire con- trol computer or integrated system processor responsible for targeting information and sensor pre-pointing.
• Joint Precision Approach and Landing System, a joint operational capabil- ity for U.S. forces to perform assigned missions from fixed-base, tactical, shipboard, and special operations environments under a wide range of meteorological conditions.
• Common Transponders, which incorporate all the advanced features required in today’s global military and civil air traffic control envi- ronments by using an open system architecture design and high-density circuit technology to ensure ongoing versatility and future utility through software-only upgrades.
• Single Channel Ground and Airborne Radio System, a tactical air- borne radio subsystem that provides secure, anti-jam voice and data com- munications with single-frequency and frequency-hopping modes.
• Aviation Tactical Communication System, an airborne VHF/UHF line- of-sight and tactical satellite system that supports DOD requirements
for airborne, multiband, multimis- sion, secure anti-jam voice, data, and imagery network-capable communi- cations in a compact radio set.
• HF Radio, an easy-to-operate, multi- functional, fully digital signal processing HF radio intended to provide reliable digital connectivity for airborne applications.
• Joint Tactical Radio System Airborne Maritime Fixed, the transformational 2-channel radio system and common ancillaries that support platform integra- tion and joint service interoperability.
Communications and Mission Planning
In 2009, PD ANMP stood up with the mission of providing the warfighting avi- ation community with materiel solutions necessary to maintain, integrate, and improve communications and mission planning. The primary products used to accomplish this mission are the Improved Data Modem (IDM) and AMPS.
The IDM, developed as a fully digital replacement for the Airborne Target Handover System (ATHS) of the 1980s, was designed by the U.S. Navy in 1991 for U.S. Air Force short-range, close-air support data communica- tion. It was subsequently adopted by the Army to satisfy the unique Army aviation requirements to connect the Tactical Internet for Command and Control (C2) with the Aviation Tactical Operations Center.
