Nathan Strout The Space Development Agency is seeking proposals for its first batch of satellites, which will make up its initial transport layer — an on-orbit mesh network that will connect space-based sensors with terrestrial shooters. According to the May 1 solicitation, SDA is looking to award two contracts to build a total of 20 small satellites, which will comprise Tranche 0 of the National Security Space Architecture, a proliferated, low-Earth orbit constellation that will fulfill a multitude of military needs, including tracking hypersonic weapons; providing alternative position, navigation and timing data; delivering beyond-line-of-sight targeting; and more. Ultimately, the agency envisions a constellation made up of hundreds of interconnected satellites. Ten of those Tranche 0 satellites will form the agency's initial transport layer. The spiral development approach The agency is taking a spiral development approach to its National Security Space Architecture. Tranche 0 will be a testing and training segment that will demonstrate the integration of the architecture with other war-fighting efforts and inform future SDA developments. Tranche 0 is anticipated to be on orbit in the fourth quarter of fiscal 2022, with the SDA adding new tranches of satellites every two years, increasing the constellation's size and capabilities. Launch services will be acquired through the Orbital Services Program 4 contract or follow-on contracts. The philosophy behind the spiral approach is that the two-year cycles allow the agency to rapidly put new capabilities on orbit in response to evolving threats. Instead of waiting years for the perfect satellite system, the agency wants to push technologies that are currently ready into orbit as soon as possible, giving war fighters increased capabilities in the near term. With Tranche 0, the SDA wants to achieve periodic, regional, low-latency data connectivity. With Tranche 1, which will add 150 satellites to the constellation, the agency plans to provide persistent regional connectivity. Building a mesh network The National Security Space Architecture will be made up of several layers serving different functions. Tranche 0 will establish the transport layer, a space-based mesh network that will be able to pass data from one satellite to the next. The mesh network will operate as part of the Integrated Broadcast System, the Defense Department's standard network for transmitting tactical and strategic intelligence and targeting data. The key technology that will enable the transport layer are optical inter-satellite cross links, providing approximately 1 Gbps connections between the satellites. Each Transport Layer satellite will have four such cross links — forward, behind, right and left — which will allow them to pass data on to the nearest or next-nearest transport layer satellite operating in the same orbital plane. The satellites will also be capable of cross-plane cross links, meaning they will be able to connect to non-transport layer satellites operating above or below them. Assuming that they also have optical inter-satellite cross links, these non-transport layer satellites would then be able to pass data through the transport layer's mesh network to another satellite or even to a terrestrial shooter. For example, it could work like this: A space-based sensor collects imagery that it wants to pass to a ground-based system, but it is not within range of any ground station. No problem. The sensor would pass on that imagery to a transport layer satellite via an cross-plane optical cross link. The data would then bounce from transport layer satellite to transport layer satellite until it arrives above its destination, where it would then be downlinked to an optical ground terminal or distributed to the appropriate weapons system via the Link 16 tactical data network. In theory, this would allow shooters to receive space-based sensor data in near-real time. Since the SDA plans to continue building on the transport layer in subsequent tranches across multiple vendors, the optical inter-satellite cross links will need to be designed with interoperability in mind. The SDA also wants radio frequency cross links as a backup to the optical cross links. Tranche 0 will include 10 transport layer satellites — three of which will include Link 16 payloads. During an April industry day, SDA Director Derek Tournear said this initial, space-based mesh network will form the space network component to the Defense Department's Joint All-Domain Command and Control enterprise, or JADC2. “The transport layer, which is what the draft [request for proposals] and the industry day was talking about today, is going to be the unifying effort across the department. That is going to be what we use for low-latency [communications] to be able to pull these networks together, and that, in essence, is going to be the main unifying truss for the JADC2 and that effort moving forward. That is going to be the space network that is utilized for that,” Tournear explained. The agency has six goals for its Tranche 0 transport layer: Demonstrate low-latency data transport to the war fighter over the optical cross link mesh network. Demonstrate the ability to deliver data from an external, space-based sensor to the war fighter via the transport layer. Demonstrate a limited battle management C3 functionality. Transfer Integrated Broadcast System data across the mesh network to the war fighter. Store, relay and transmit Link 16 data over the network in near real time. Operate a common timing reference independent of GPS. According to the request for proposals, the SDA plans to award a contract Aug 10, with delivery expected by July 31, 2022. Responses to the solicitation are due June 1. https://www.c4isrnet.com/battlefield-tech/space/2020/05/05/heres-what-the-space-development-agency-wants-from-its-first-10-satellites/

Mark Pomerleau WASHINGTON — The Army has created a new entity within is operations and plans directorate, G-3/5/7, to focus on non-physical capabilities and better ready the service for multidomain operations. The new directorate, Department of the Army's Management Office-Strategic Operations (DAMO-SO), was created about six months ago and replaces DAMO-CY, which focused primarily on cyberspace operations. The organization now encompasses cyber, electronic warfare, information operations, space, enterprise IT networks, tactical communications networks, data architectures and artificial intelligence. “We're an organization that pulls together a lot of the multidomain operating capabilities. Things like cyber, electronic warfare, information operations, space,” Brig. Gen. Martin Klein, director of DAMO-SO, told C4ISRNET in a July 20 interview. “We're also bringing into the directorate the capabilities of really underwriting the Army's ability to digitally transform into this new era ... Part of what we've been asked to do is underwrite multidomain operations and then to digitally enable our warfighting systems.” The office will serve as the Army point of contact for joint initiatives with the other services, namely Joint All-Domain Command and Control (JADC2). Klein said his organization is the Army's lead entity for the JADC2 cross functional team. The team will also work with the Air Force in experimenting with its Advanced Battle Management System, which is considered an early possibility for the JADC2 program. “One of the tenets of multidomain operations is the recognition that we fight and win as a joint force,” he said. “A lot of what I do, frankly, is develop capabilities with the Army but coordinate those capabilities throughout our sister services to make sure that we can fight and win certainly in the competition space ... in conflict if it should arise.” Additionally, the team will work to standardize data and data architectures within the Army and joint force to ensure interoperability. But a key distinction between the predecessor organization and the newly formed office was the importance of space, Klein said. “As the Army looked at the Multidomain Task Force and, in particular, how to win in multidomain contested operations, we came to the realization of how interdependent our space-based capabilities are,” he explained. One of the key premises to the office was the notion of better posturing the Army in the competition phase against near peer adversaries that are seeking to exploit the so-called gray zone below the threshold of armed conflict. The new office works as an integrator across the Army – especially within the G-3/5/7 – of how offices can better organize, restructure or resource these non-kinetic capabilities. Along with Army Futures Command, it also looks at emerging capabilities and, with the various program executive offices, examines what capabilities are needed now. “What we primarily do is we address this capability through a policy lens, but we also go forward and do resourcing ... we work with a strategy team here in the Army G-3/5/7 to make sure that competition and conflict strategies are deconflicted and we certainly work without operational folks ... to make sure when we go through a plan and when we mobilize ... that we have the right organizations within our cyber, electronic warfare and our information operations space,” Klein said. Klein said he was tasked to keep his finger on the pulse of the emerging multidomain concept as others across the Army look at how the Army will fight in 2028 and beyond. In doing so, his outfit will make recommendations regarding force structure changes or capabilities that could be endorsed by the Army. “End to end, we're developing a desired capability that our chief and that our secretary of defense need in order to fight and win against a near peer adversary,” he said. DAMO-SO will participate in upcoming exercises and advise on combat training center rotations to ensure units are defending against these non-kinetic tools that can cripple communications. One exercise includes the forthcoming Project Convergence, a data sharing test and experiment to take place in the fall. “It's really bringing long range precision fires, weapon systems and some of our modernization efforts together under the rubric of a data enabled cloud orchestrated system to be able to do the experimentation necessary,” he said. Ultimately, Klein said he hopes the office will provide a great benefit. “As that lead integrator, we can bring multiple perspectives from multiple different vantage points all the way form strategic down to the tactical to make sure that 0 as we're developing these capabilities, as we're exercising and as we're coming up with new things of use in the existing systems - we get back best practices,” he said. https://www.c4isrnet.com/smr/information-warfare/2020/07/21/the-armys-new-directorate-eyes-multidomain-integration/
