GSSI, or Geophysical Survey Systems, Inc., is a mid-sized U.S. manufacturer focused on ground penetrating radar and related subsurface imaging equipment. The company has a long history, dating back to 1974 when it introduced the first commercial GPR system, and it has since accumulated a record of industry firsts that emphasize accuracy, quality, and reliability. Its portfolio covers a broad range of subsurface imaging and electromagnetic induction tools used in archaeology, forensics, geology and environmental work, utility detection, concrete inspection, and transportation infrastructure condition assessment. GSSI is based in Nashua, New Hampshire, operating within the appliances, electrical, and electronics manufacturing sector. In March 2026, Topcon Positioning Systems announced a collaboration with GSSI to integrate GSSI's ground penetrating radar systems with Topcon's GNSS solutions and mass data workflow software. The partnership signals an ongoing alignment with broader data and positioning ecosystems to support complex field-imaging tasks across utilities, infrastructure, and related industries.
