Current military communication systems have limited ability to support mobile, distributed operations in remote geographic areas due to the small size of networks and relatively short range of military radios. Today, military mobile ad hoc networks (MANETs) are used to relay communications services beyond the range of a single radio.
For decades, U.S. military air operations have relied on increasingly capable multi-function manned aircraft to execute critical combat and non-combat missions. Adversaries’ abilities to detect and engage those aircraft from longer ranges have improved over time as well, however, driving up the costs for vehicle design, operation and replacement. An ability to send large numbers of small unmanned air systems (UASs) with coordinated, distributed capabilities could provide U.S. forces with improved operational flexibility at much lower cost than is possible with today’s expensive, all-in-one platforms—especially if those unmanned systems could be retrieved for reuse while airborne.
The Mobile Hotspots program envisions air, mobile and fixed assets that provide a gigabit-per-second tactical millimeter-wave backbone network extending to the lowest-echelon warfighters.
The Network Universal Persistence (Network UP) program seeks to develop and demonstrate radio technology that maintains network reliability through periods of frequent signal degradation that may occur during operations in multiple environments. From time to time, network outages may occur and data transmission may be challenged.
PCAS seeks to fundamentally increase Close Air Support effectiveness by enabling dismounted ground agents and combat aircrews to share real-time situational awareness and weapons systems data.
