About the company
Geophysical Survey Systems Inc., doing business as GSSI, manufactures ground penetrating radar (GPR) and electromagnetic induction systems for federal agencies as a prime contractor (99% of recent awards), competing predominantly in full-and-open procurements rather than under set-aside categories. GSSI is a small business child entity of OYO Corporation U.S.A., a foreign-owned organization, and operates from Nashua, New Hampshire. The company specializes in portable, battery-operated GPR equipment for infrastructure assessment, archaeological investigations, concrete scanning, pavement analysis, and subsurface feature detection across 84 distinct federal customer agencies.
GSSI's customer concentration spans civilian infrastructure and defense agencies with no dominant customer by share. The Army Engineer Research and Development Center leads by award count (22 awards, $422 thousand combined potential value) followed by the Department of Agriculture Natural Resources Conservation Service Northeast Region (16 awards, $330 thousand) and the Department of Homeland Security Chief Procurement Officer (4 awards, $179 thousand). The top five customer agencies by either award count or potential value represent only 27% of total awards and 19% of combined potential value, indicating a highly distributed customer base where no single agency anchors the footprint. Representative prime work includes a $91 thousand definitive contract with ERDC in September 2025 for a RoadScan GPR system to determine asphalt pavement layer thickness at Vicksburg, Mississippi; a $137 thousand firm fixed-price purchase order from Army Intelligence and Security Command in July 2025 for an FGFLEX NX25-KIT GPRS system with completion by September 2027; and a $67 thousand delivery to the EPA Office of Land and Emergency Management in September 2023 for a portable GPR unit for land and emergency management functions.
GSSI operates substantially through the GSA Multiple Award Schedule, where 86 task orders carry $1.8 million in combined potential value, and the Federal Supply Schedule GS24F1008B, which holds 32 task orders valued at $354 thousand. The vendor competes on approximately two-thirds of recent awards under small business set-aside designations (Total Small Business or equivalent) and one-third as full-and-open, non-set-aside awards. Only three awards carrying $203 thousand combined potential value reach ultimate completion within the next twenty-four months, indicating minimal recompete cliff pressure in the immediate term. Activity has declined modestly — seven awards in 2022–2023, nine in 2024, four in 2025, and three through September 2026 — reflecting the seasonal and project-driven nature of geophysical equipment procurement. GSSI subcontracts minimally (1% of recent awards), with named prime engagement limited to Pantexas Deterrence LLC for Pantex Plant management and operations, Atlantic Diving Supply Inc. for single-channel GPR data acquisition systems, and Leidos Inc. for Antarctic program science and maintenance operations support.
