About the company
GMW Associates Inc., a small business distributor and integrator of magnetics-based sensors and instrumentation based in San Carlos, California, supplies precision magnetic measurement equipment and calibration services to federal agencies as a prime contractor on 97% of its recent awards and does not compete under formal SBA set-asides, though it qualifies for total small business designations when solicitations carry them.
The company's capability portfolio centers on fluxgate magnetometers, three-axis magnetometer arrays, high-field electromagnet systems, current transducers, sensor calibration services, and specialized magnetic field measurement instruments for scientific research, metrology, and defense applications. Recent prime awards include a $53,370 high-field electromagnet system for MRAM device metrology delivered to NIST in New Zealand (awarded September 2026), a $231,160 Bartington magnetometer for NAVSEA (awarded September 2025), a $154,000 array of eight 3-axis magnetometers with 500 microtesla range for the Navy (awarded July 2023), and a $249,990 magnetometer array also for NAVSEA (awarded October 2022). Calibration services represent a recurring revenue stream — GMW has delivered LEM sensor calibrations, fluxgate magnetometer calibrations, and related sensor verification work to NAVSEA at values ranging from $4,272 to $50,739 per task.
Customer concentration is bifurcated between defense and civilian scientific agencies. The top five customer agencies by award count and potential value account for 64% to 74% of recent activity, led by NAVSEA (28 awards, $1.3 million combined potential value) and the National Institute of Standards and Technology (26 awards, $1 million combined potential value), with the Navy Office of Naval Research (18 awards, $293 thousand), NASA Shared Services Center (6 awards, $195 thousand), and Army Materiel Command (6 awards, $109 thousand) completing the active set. Award volume has remained modest but steady — six awards per year in 2023 and 2024, declining to two awards in 2026 year to date. Only two awards face completion in the next twenty-four months, representing $94 thousand in recompete exposure.
GMW operates at the equipment and materials supplier tier rather than as a systems integrator or services prime. The company's subcontract footprint is minimal — four sub-awards documented across Applied Physical Sciences Corp (DARPA flux probe supply), Fluor Marine Propulsion (Naval Nuclear Laboratory current transducer and probe supply), and NASA JSC (current sensor flux gate modules). Primary NAICS coding reflects analytical laboratory instrument manufacturing and electrical signal measurement instrument production; the company does not hold seats on government-wide acquisition contracts or indefinite delivery vehicles, instead winning task orders through direct solicitation to its San Carlos facility or to international performance locations (Switzerland, New Zealand).
