FIELDING THE FUTURE
EMERGING CAPABILITIES
In January, the PEO C3T, Network CFT and the CCDC C5ISR team concluded the initial phases of medium Earth orbit satellite testing with prototype ground satellite terminals, at the C5ISR Center’s Joint Satellite Communications Engineering Center. The Army, in collaboration with industry, is developing a road map for testing emerging satellite communications capability in training and exercises, to inform Army decisions on integrating innovative technologies into the greater network.

may require different solutions. Instead, the Army will capital- ize on the strengths of all of these evolving capabilities to provide commanders and signal officers with multiple network commu- nication capabilities and signal path options to optimally support their missions.
MORE BANDWIDTH, LESS LATENCY LEO and MEO satellite communication capabilities are expected to provide huge increases in network bandwidth while signifi- cantly reducing latency, the time it takes for data to travel from the source to the destination. Both are must-haves for many of the Army’s network modernization efforts. When compared with current GEO solutions, the anticipated deployment of mega- constellations operating in LEO could provide a 100 times increase in bandwidth and a 10 times reduction in latency, while providing network communication services to a greater density of users supporting a mission. MEO bandwidth increases will be slightly less, but significantly more than current GEO capabil- ity provides. Bottom line: Tese improvements will enable more data to be sent faster to a larger number of users.
Te anticipated proliferation of LEO and MEO satellite capabili- ties by commercial industry provides the potential to significantly increase the communications capacity across the Army. It would deliver expeditionary, mobile, beyond-line-of-sight communica- tions with increased bandwidth and low latency to better enable the Army’s mission command systems.
High-throughput systems in GEO, LEO and MEO solutions are also expected to reduce stress on overburdened military GEO satellite capability and provide more connection options for increased network resiliency. LEO satellite constellations will contain numerous small satellites at a much lower altitude, with the natural physical resiliency that comes with having so many satellites. Te signals don’t have to travel as far to get to the satel- lite, so the latency is significantly reduced, which will improve the performance of the network, especially for real-time applications.
Among many potential applications, LEO and MEO capabil- ities are expected to enhance the Army’s ability to aggregate data supporting artificial intelligence and to leverage edge cloud services. Edge cloud services enable Soldiers to gain quick access to data and software through multiple small data centers located close to the user, which reduces bandwidth usage and latency compared with accessing large, distant data centers. With success- ful inter-satellite links, these solutions could also enable the Army to put more complex network functions and mission support capabilities in safe sanctuaries, pulling complexity out of tacti- cal echelons and putting it where it can be maintained effectively with more resources in a less contested environment.
Of significant importance, the Army plans to use future LEO and MEO solutions to support Joint All Domain Command and Control (JADC2)—a major effort that will leverage capabilities across all domains and mission partners to achieve battlefield
