Enabling Exponential Combat Capabilities
Our office in Aberdeen, Maryland was established when our Aberdeen site lead retired from over 20 years in the Army. After serving as an infantryman with two combat tours and working in communications systems and PNT, his goal was to build the solutions he knew could provide exponential combat capability in the field and, most importantly, save American warfighter lives.
Our team has a clear and unwavering focus on building and delivering the capabilities our soldiers need, with emphases on improved communications systems, navigation, electromagnetic warfare, artificial intelligence, and disruptive technologies.
We are creative, curious, disciplined, and diligent as we know we are making a real impact on the safety and efficacy of our troops.

Our Work

Electromagnetic Warfare
We develop systems across the spectrum of electromagnetic warfare (EW) in the domains of electronic support and electronic attack capabilities. We specialize in the development of decentralized and cognitive EW systems that can be deployed in novel ways to deliver non-kinetic effects as part of a combined multi-domain maneuver concept. With decentralized EW, we place capability at the forward edge while considering technology insertion within more complex systems.

Force Electronic Attack Radio (FEAR)
FEAR presents a new and novel approach to conducting electronic attack through low-SWaP (size, weight, and power) devices which can deliver a variety of non-kinetic effects on the battlefield.
FEAR decentralizes electronic attack capability by providing modular and scalable capability to deliver complex attacks on adversary systems.

Resilient Satcom
We support the Army and the DoD with subject matter expertise in the field of tactical communications. Our team of experts understands the complexities of resilient waveforms as well as how to test and assess their performance in a relevant operational environment using hardware-in-the-loop (HWIL), modeling and simulation, and demonstrations to assess the correct combination of resilient capabilities to meet user needs.

RAIDER
Our team in Aberdeen is a pioneering system integrator in the field of radio frequency machine learning (RFML). Radio Frequency-Based Artificial Intelligence to Detect, Engage, & React (RAIDER) is under development to identify novel approaches to identify known and unknown signals of interest. We accomplish this through a complex approach to signal processing and RFML techniques which can support friendly freedom of maneuverability and survivability.

Lightweight Satnav
Lightweight Satnav (LWS) is a new PNT signal that will be transmitted from the Space Development Agency (SDA) Low Earth Orbit (LEO) satellites.
LWS leverages commercial cryptography and the DoD network to provide military encryption with no critical program information (CPI). We have developed a transmitter and receiver that have been successfully demonstrated in the field.

Assured PNT
Our team has both a deep understanding of the current state of assured position navigation and timing (A-PNT) development and a keen eye on future needs as they evolve.
We are always looking for new, cost-effective A-PNT solutions that can be leveraged to provide reliable A-PNT information to our warfighters.

Software Development
We specialize in software development across the product lifecycle, including research and development through procurement and sustainment activities. We employ a disciplined, requirements-driven approach to software development which captures the system design and manages progress through the use of multiple industry tools such as GitHub and Jira to create the background algorithms, embedded software, and the graphical user interface (GUI) tools.

Nuclear Safety / AFMAN-119 Software Systems Engineering
Our experience in reverse-engineering large OEM software, completing development of that software, testing, and integrating is a rare combination as the United States looks to modernize the strategic arsenal. Our expertise has been applied to develop software in support of AFMAN 119 requirements, which represent some of the most critical functions for ensuring human intent is executed in a safe and effective manner.

Open Systems Architectures
Our office is located directly outside of Aberdeen Proving Ground (APG), which is the headquarters of the Army Command, Control, Communications, Computers, & Cyber Intelligence, Surveillance, & Reconnaissance (C5ISR) Center. The C5ISR Center is home to the Army’s C5ISR Modular Open Suite of Standards (CMOSS), and our team supports both CMOSS and sensor open systems architecture (SOSA) developmental efforts through systems engineering, integrating, and testing.

Certified DevOps Environments
We believe in the strength of agile project management. Our programs hold daily standups, and we manage work through a disciplined approach utilizing tracking mechanisms such as Jira.
We use these standups and sprints to focus on building incremental capability that meets our customer’s needs.
Aberdeen Leadership
Chris Bieber
Vice President

Chris Bieber is a defense technology innovator with expertise in tactical communications, electromagnetic warfare, and PNT. Chris founded the IS4S Aberdeen site in 2020 after retiring from 20+ years in the US Army.
As a soldier, Chris served as an enlisted infantryman (11B), infantry officer, signal officer and acquisition officer. Chris completed year-long deployments in a combat infantry role to both Iraq and Afghanistan. Upon leaving the Infantry, Chris was cross trained as a signal officer in tactical communications and led a company of small SATCOM and network teams tasked with mission support at various locations in the Pacific. As an acquisition officer, Chris managed modernization for a large portion of the Army’s tactical network, served as a chief network integrator for experimentation in Fort Bliss, TX, and led technical (modeling and simulation) assessments in the Army’s DEVCOM PNT lab to inform Army decisions.
At IS4S, Chris continues to build expertise in the areas of resilient SATCOM, artificial intelligence/machine learning, small form factor electromagnetic warfare techniques, software development, and positioning, navigation and timing (PNT). Chris is often called upon by trusted government partners as an expert who can inform decision makers on the tactical employment of complex networks and systems.
Chris oversees the IS4S Aberdeen site operations.
