The operations of a number of additional DoD systems rely on spectrum between 1755 and 1850 MHz in addition to those of the four major DoD functional capabilities described above. Long-range point-to-point microwave system operations represent a majority of these additional systems. These systems primarily operate at fixed locations and employ directional antennas. A number of other mobile operations are also authorized in this band. Two mobile systems, the Combat Identification for the Dismounted Soldier (CIDDS) and the Land Warrior Local Area Network (LAN), are developmental systems whose operations also are dependent on spectrum in this band segment. Land Warrior is a first-generation integrated fighting system for dismounted soldiers. A number of Unmanned Aerial Systems (UAS) are authorized to operate in this band. These systems transmit video and status data from the UAS to the ground control system (GCS) using analog FM video and data on subcarriers. Fixed point-to-point microwave, CIDDS, the Land Warrior LAN, and UASs represent significant other uses of the 1755 to 1850 MHz band.
The Army Corps of Engineers (ACE) operates a nation-wide system of fixed point-topoint microwave links providing connectivity for monitoring water levels, remote alarms, and communications for remote locks, dams, and other water systems. These systems provide microwave links where no commercial communications connectivity exists. The systems are essential to the ACE operations because they allow for remote monitoring of critical waterway operations negating the need for full time, on-site personnel. The systems provide key maintenance parameters, alarm indications, and provide personnel at the facility with communications capability. These systems help ensure the safety and integrity of the nation’s waterways and help prevent catastrophic events that could cost lives and economic damage as well as environmental damage.
The Land Warrior system is a close combat communications system for infantrymen, combat medics, combat engineers, forward observers, and scouts. With Land Warrior, the soldier can both send and receive voice, video images, map overlay information, operational plan diagrams, etc. The system provides situational awareness information among team members, improves survivability and increases mission effectiveness while reducing the soldier’s equipment load.
The Combat Identification of the Dismounted Solder (CIDDS) program’s purpose is to help prevent US forces from firing on friendly forces, otherwise known as fratricide. CIDDS employs a laser interrogator with a RF response to provide identification of friendly forces by individual and automatic weapons users. The laser interrogation signal message identifies a set of random frequency channels, spaced throughout the 1755-1850 MHz band for the transponder to use in its response. Current program documentation indicates approximately 100,000 CIDDS units will be procured to outfit dismounted soldiers in all three military services.
The Pointer UAS is a production-ready, electric, hand-launched UAS designed for remote monitoring and surveillance. The UAS transmits real-time images taken by a black and white, color, or thermal camera. A variety of alternative payloads such as air pollution sensing, 40 chemical weapons detection, and unexploded land mine detections are currently being developed. The video link operates in the 1755-1850 MHz frequency band.
The Aberdeen Test Center (ATC) Range telemetry System provides a multi-link radio telemetry communication capability throughout the many test ranges and facilities of the ATC. It consists of several fixed receiving stations located at the high usage ranges/test areas and many transportable (vehicle housed) receiving stations that are emplaced at any of the multitude of ATC test areas or remote test sites when required to support testing projects. The test mission
and workload of the ATC requires daily support by the telemetry system. It is vital to the accomplishment of the test and evaluation of military equipment, primarily combat and tactical vehicles, and many items of support equipment. Testing under dynamic conditions is a requirement, and the telemetry system provides the capability to transfer engineering measurements from the moving vehicle to a data collection center.
The Air Force Television Ordnance Scoring System (TOSS) provides a television ordinance scoring capability to range users in support of exercise and test missions. TOSS is a field proven accurate weapons scoring system with a night scoring capability using infrared cameras.
