G Systems

What G Systems does

G Systems, Inc. is a privately held custom test and measurement systems integrator headquartered in Irving, Texas, founded in 1990 by Lynda Harrell as a Woman-Owned Small Business (WOSB). The company designs, assembles, and modernizes automated test equipment (ATE), data acquisition (DAQ) systems, RF test systems, and electromechanical assemblies for U.S. Department of Defense programs, defense prime contractors — including Lockheed Martin, Bell Helicopter, Leonardo DRS, Northrop Grumman, L3Harris, and BAE — and select commercial customers in aerospace seating, flight simulation, solar energy storage, and research applications. G Systems is registered for ITAR compliance, holds ISO-9001:2015 certification (valid through December 2026), adheres to NIST SP 800-171 cybersecurity standards, and maintains six NAICS codes plus CAGE Code 3HPP5 enabling direct federal contracting.

The company's technology platform is anchored on National Instruments tools — LabVIEW, LabVIEW FPGA, LabVIEW Real-Time, TestStand, DIAdem, SystemLink, and CompactRIO hardware — augmented by C/C++, custom FPGA firmware, SOLIDWORKS, and Altium Designer. Proprietary elements include a flexible test executive with mass interconnect / interchangeable test adapter (ITA) architecture for cross-program reuse, ruggedized field-portable instruments such as the Army MLRS automated Console and Simulation Unit (rated -40 to 70°C at 50g shock), high-channel-count DAQ architectures exceeding 3,000 channels deployed 24/7 for 15+ years on the F-35 Vehicle Systems Integration Facility, and a codified obsolescence management methodology published as a white paper. Integration partners include Keysight Technologies, Pickering, Virginia Panel Corporation, and United Electronic Industries.

Revenue is generated primarily through firm-fixed-price contracts awarded via direct U.S. government procurement and defense prime subcontracting, with supplementary commercial quote-based engagements and a small catalog of turnkey test products (signal splitters, valve leak measurement systems, MIL-STD-1553B interfaces, blackbody reference emitters). The company has been awarded 19+ U.S. Navy contracts over its history, including an $11.4 million Vertical Launching System Combined Missile Test Set contract. Distribution is exclusively direct, supported by content marketing (white papers, case studies), an active LinkedIn presence, and NI co-sponsored technical events. Mark Krause succeeded founder Lynda Harrell as CEO on January 1, 2024 in a planned multi-year transition; Harrell remains Chairman.

Revenue model

1. Defense & Government Contract Manufacturing: G Systems receives firm fixed price contracts from the U.S. Navy and other government agencies for the procurement, fabrication, assembly, test, and delivery of custom test systems and subsystems. Revenue is project-based, non-recurring, and tied to specific contract awards (e.g., $11.4M VLS CMTS contract). The company has been awarded 19+ Navy contracts related to VLS equipment.
2. Turnkey Custom Test System Design and Build: Design, development, and delivery of fully integrated custom automated test equipment (ATE), data acquisition systems, and electromechanical assemblies. Customers include defense primes (Lockheed Martin, Bell Helicopter, BAE) and commercial companies. Projects range from prototype/engineering builds to high volume complex systems. Revenue recognized upon delivery of completed systems.
3. Product Sales (Turnkey Test Equipment): G Systems manufactures and sells turnkey test and measurement products including signal splitters, valve leak measurement systems, configurable portable DAQ systems, analog/digital isolators, Ethernet isolation interfaces, MIL-STD-1553B interfaces, RS485 isolators, controlled rack fans, and Blackbody Reference Emitter instruments. These are standard or configurable products sold to customers needing immediate test capability.
4. Electromechanical Assembly Production Services: Build-to-print production services including subsystem assembly, electromechanical assembly, turnkey cabinet rack builds, and ruggedized case integration. Services range from low-volume prototype builds to high-volume serial production. Also includes supply chain management, rapid component sourcing, and qualification testing (MIL-STD-810, DO-160).
