Understanding Warfighter Performance from the Inside Out
Measuring Biological Aptitude (MBA) aims to identify, understand, and monitor in real time the biology that underlies success in specialized roles
A new program out of DARPA's Biological Technologies Office could help the Department of Defense enhance and sustain military readiness both by revolutionizing how troops train, perform, and recover, and by mitigating shortages of highly qualified candidates for extremely specialized roles. The anticipated outputs of the Measuring Biological Aptitude (MBA) program are a set of biomarkers — measurable indicators of biological processes — that correspond to traits of highly effective performance in a given role, along with new tools to measure and report on those biomarkers in real time. This information will enable individual warfighters to understand and affect the underlying biological processes that govern their success. MBA technologies could improve training, team formation, mission performance, and post-mission recovery, yielding a better prepared, more effective, more resilient force.
At its core, MBA seeks to shed light on the biological factors and processes that support peak performance in each of a set of military specializations. The research will work backwards from phenotypes — that is, how an individual's fixed genetic code expresses as externally observable cognitive, behavioral, or physical traits — and attempt to establish the biological mechanisms that translate underlying genetic makeup into phenotypic traits. At present, those mechanisms of translation — also known as expression circuits — are largely a mystery. MBA researchers will develop new assays and technologies to monitor and report on the biomarkers that reveal the activity of key expression circuits.
“With existing technology scientists are able to read out genotype and measure and observe certain aspects of phenotype. Most of what happens in between is a black box,” said Eric Van Gieson, the MBA program manager. “DARPA believes that the information inside the box — these expression circuits — can be predictive of how an individual will respond to a given stimulus or scenario, and more importantly, we believe it will help inform the individual on how to improve their performance throughout their career.”
Researchers supporting MBA will initially analyze samples and other data collected from high-performing troops across select military specializations to identify biological signatures of successful performance in each of those roles and determine how they can be measured. For instance, maintaining a lowered heart rate during combat is a valuable trait and easily measured with existing wearable technology. Adaptable problem solving, resilience, and cognitive flexibility are extremely valuable, but less easily measured. MBA analyses should reveal an array of such traits and the expression circuits responsible for them.
If DARPA succeeds, the resulting MBA system could support military readiness in various ways.
The first improvement relates to how the military initially evaluates recruits and subsequently develops candidates for specialized roles. Many of these roles currently suffer from shortages of qualified candidates, even as more pervasive use of complex technologies and an expanding set of mission profiles are increasing demand for uniquely skilled personnel.
For at least the past 50 years, initial assessment of military service members has remained essentially unchanged, comprising a basic medical screening, a standardized physical readiness test, and a written test known as the Armed Services Vocational Aptitude Battery (ASVAB) for enlisted personnel. Scores on the ASVAB feed into the preliminary determination of an individual's qualification for certain military occupational specialties. As a service member's career advances, future placement into other roles does not follow a prescribed protocol and can be based in large part on subjective measures.
Against this backdrop, MBA technology could increase the objectivity of the criteria used by military selection committees, remove biases, and raise the baseline of performance for incoming recruits. Additionally, by taking biology into account, the results from MBA measurements could reveal to individuals career options that might not be apparent based on commonly accepted, externally observable traits alone.
The second improvement ties to training, both before and after an individual pursues a military career. MBA technology could allow a user to assess his or her personal potential for specialized roles and proactively nurture the traits that are characteristic of successful performers.
“Genotypes are fixed, but phenotypes are not. Biology is fundamentally adaptable, and that is the key to enabling performance improvements,” Van Gieson said. “What we're planning to deliver with MBA is a set of continuously updated information that empowers individuals to track their progress throughout their careers and quickly identify what aspects of training and preparation are the most productive.”
Third, during missions commanders could employ real-time reporting of changes in service members' biomarkers to inform how a military operation unfolds, adding a layer of biological awareness to provide a more complete assessment of the mission space. Commanders could shift resources or adjust strategies and tactics based on how squad members are performing. Following a mission, biomarker reporting could likewise guide recovery practices and indicate potential health issues.
The overall MBA program will be informed by consultations with independent expert advisors in the ethical, legal, social, and regulatory aspects of the work, with particular emphases on privacy, data protection, and responsible utilization of data by individuals. MBA performer teams will be required to provide medical guidance as part of any human study through an embedded genetic counselor, sports therapist, or similar specialist.
“Human beings are extremely complex, and although we expect to gain valuable new insights by measuring biology, we also understand that people are not locked into predetermined fates,” Van Gieson explained. “Any breakthroughs we achieve in the MBA program will necessarily be used to address shortages in critical roles by expanding opportunities, not limiting them. If we can provide people with information on their unique biology, and empower them to affect and measure gains in key traits, we'll have opened career pathways that they may not have previously considered.”
DARPA will hold a Proposers Day on February 12, 2019, in Arlington, Virginia, to provide more information about MBA and answer questions from potential proposers. For details of the event, visit https://go.usa.gov/xEZeT.
A forthcoming Broad Agency Announcement will include complete program objectives, schedules, and metrics. Team should have experience in human performance, phenotyping, multi-scale biology, physiology, biomarker detection and tracking, device development, and various other aspects that will be specified in the announcement.

Are software-defined ground stations the next big leap? Kratos is betting on it.
Nathan Strout WASHINGTON — Software-defined payloads have revolutionized how industry and the government approach satellites. So why not software-defined ground stations? That's the question Kratos is asking. On Oct. 20, the longtime Pentagon contractor with experience building satellite support systems unveiled its new OpenSpace platform — a family of virtual products that applies the software-defined approach to the ground station. OpenSpace uses an open standards, cloud-based system that can be continuously adjusted to mission needs without having to install new hardware. Pentagon officials often complain that the nation's current satellite ground architecture is stymied by stovepiped, custom-built proprietary ground systems. The department has said it plans to move to an enterprise ground system, but it's not there yet. Kratos hopes that OpenSpace can at least be part of the solution. Because the platform is software-based, satellite operators no longer need to use custom-built hardware to connect to and control their on-orbit systems. Instead, OpenSpace virtualizes the ground system in software, effectively allowing it to be linked up to any antenna with a digital converter. “It's a big announcement from our perspective in that it's going to address a lot of the key issues that are challenging the space industry across the board, and especially some of the issues that the defense and government world is going through,” Neil Oatley, Kratos' vice president for marketing, told C4ISRNET. Software-defined payloads have opened up new possibilities in the space industry. Previously, satellites were designed to be rather static tools — once placed in orbit, it becomes all but impossible to physically replace the payload hardware or refigure the software. That means that the system you launch is the system you've got, regardless of whether your mission needs change or you want to do something new with your orbital tech. The Defense Department is investing in capabilities that could eventually allow physical access to operational satellites via robotic space vehicles, but that's still in development. All that is just to say, when the military builds a satellite, it builds it with the expectation that the space-bound payload will be largely static over the lifetime of the spacecraft. In other words, it will do the mission it was meant to do, and not much else. “When you look at the ground today, it's the one area where we're really stuck back in 2G-type technology,” said Phil Carrai, president of Kratos' Space, Training and Cyber division. “Systems are stovepiped. They're static. They're built with custom hardware. They have software-specific technologies that are dedicated to specific satellites. And that's really making them unable to play in the coming new world.” Building a new, custom ground system for each new satellite or constellation is not only costly, but it limits flexibility. The satellite-specific nature of existing ground systems makes it difficult to build third-party applications that can easily be installed across systems. Moreover, it limits the ability of operators to simultaneously connect to multiple constellations using the same ground system. However, industry has created a workaround. Satellites may not be physically inaccessible, but they frequently communicate with operators over radio frequency signals. If a given payload's functions are largely virtualized — meaning they are software-defined and not hardware-defined — then operators can alter a given satellite's capabilities and mission by simply installing new software. Hence, the growing interest in building software-defined payloads. In fact, the next GPS payload will feature an entirely digital payload. With OpenSpace, Kratos is applying the basic principles of software-defined payloads to satellite ground systems — the technology used to command and control the spacecraft once it's on orbit. The ground system is what operators use to cue, download data from, and monitor their satellites. According to Kratos, its OpenSpace platform is the first dynamic, software-defined ground system that will apply those lessons learned from the space layer to the ground layer. “What we did with OpenSpace is we actually started from scratch with an entirely new platform that is based on the fundamentals of network function virtualization (NFV) and software-defined networking (SDN),” said Greg Quiggle, vice president of product management at Kratos, comparing the platform to the architecture underlying new 5G networks. “We took that same basic premise and we applied it to the way a ground system should be built to interconnect software-defined satellites, multi-constellation networks and a terrestrial network.” A key feature that enables OpenSpace is the digitization of the radio frequency signal as close to the antenna as possible, transforming that flow of data into what is effectively a large ethernet network. “Once you've done that — you move from [radio frequency] to digital — you now can process those subchannels, that bandwidth, in software through something called virtualized network functions,” Quiggle explained. The platform takes typical purpose-built ground station hardware — splitters, channelizers, matrix switches, modulators, demodulators and much more — and recreates them in a virtual environment. Once the radio frequency data is digitized, it can be processed through all of these virtual tools. One consequence of that is the software can be run anywhere — it does not have to be located at the antenna. Operators can run this solution in the cloud or in a classified data center, said Quiggle. That also means any ground station using OpenSpace can be quickly adjusted for different uses. For instance, take an operator who needs to interact with satellites. By using an OpenSource-enabled ground station, that individual can load his or her own software-defined solution into the system, connect with the satellite, download any data and cue the spacecraft for its next tasks. Once that satellite passes out of view, a second operator can take over the ground station, load an entirely different software-defined solution and interact with the satellite as it passes over. In this scenario, both users were able to use a single ground station to communicate with their own unique satellites. In another example, the first user is ready to use one ground station to interact with a satellite as it passes overhead, but inclement weather disrupts the process. Instead of waiting for the satellite to pass overhead again, the user simply needs to find the next available ground station on the satellite's course, virtually load software and then access the satellite from there. Military applications OpenSpace is clearly set to have commercial implications. In fact, Microsoft announced Oct. 20 that it will use OpenSpace as part of its Azure Orbital ground-station-as-a-service. Azure Orbital is Microsoft's answer to Amazon Web Services' Ground Station model, which allows customers to access their satellites by renting time on Amazon's ground stations and the AWS platform. It's a business model that could be attractive to small companies looking to field small satellites without building massive, cost-prohibitive ground systems to support them. But a product like OpenSpace could make an even bigger splash in the military space community, especially when it comes to satellite communications. In a statement released earlier this year, the Space Force laid out its concept of “fighting SATCOM.” The service envisions enabling war fighters to roam among satellite communications providers to ensure forces remain connected even if one provider is jammed or unavailable. That level of fluidity requires some major changes to how the military has traditionally approached satellite communications. “One of the things that the government is looking for very specifically is the ability to create an open enterprise-wide architecture for their protected communications systems,” said Frank Backes, senior vice president for federal space-related business at Kratos. “And as they move forward with proliferated LEO [low-Earth orbit] and MEO [medium-Earth orbit] constellations to add communication options, resiliency and capability to their current geosynchronous space communications environment ... this ground architecture is very critical to the defense goals and what they're trying to achieve,” he added. Currently, the ability to roam between constellations to avoid jamming is hampered by stovepiped systems, which are designed to work with a single satellite or a set of satellites. Because OpenSpace can leverage any radio frequency antenna, digitizes that signal and process that data in software, the operator can use the same ground station for multiple constellations. Kratos certainly hopes that its system could be the ground solution for the “fight SATCOM” concept. “Today, the U.S. government on the defense side is very dependent on their own antennas and their own hardware that is deployed for their communications infrastructure and their satellite command-and-control environment. And one of the reasons for that is the hardware that is out in the field today is protected hardware: It may have specialized waveforms, it may have specialized components, it may even have specialized encryption infrastructure,” Backes said. “That limits the military to only using certain apertures for communications. As soon as you move to this dynamic environment — this OpenSpace environment that Kratos is talking about — now you have the ability to use any commercial or military antenna infrastructure for your system and dynamically configure that as needed. “Combined with the ability to move protected hardware out of the field and putting that into a controlled cloud environment, now all of a sudden I have the ability to create the resilient environment that the Department of Defense is looking for.” Kratos told C4ISRNET in a statement that the company “is providing satellite ground system engineering support on several DoD pLEO space segment teams.” In addition, the company noted it “will be bidding our OpenSpace and [Eterprise Ground Services] capabilities on pLEO systems as those opportunities mature.” “When you look at ... the new LEO and MEO constellations — just from a pure imaging/sensing perspective — we don't see how you make those happen without an element of a dynamic software-defined ground,” Carrai said. “The timing has to be second or milliseconds. That we think is going to be essential for us to really get what we're paying for and we need from a U.S. constellation perspective.” https://www.c4isrnet.com/battlefield-tech/space/2020/10/20/are-software-defined-ground-stations-the-next-big-leap-kratos-is-betting-on-it/
