GSSI's Ground Penetrating Radar Systems

GSSI, Geophysical Survey Systems Inc., is the originating manufacturer of commercial ground-penetrating radar technology and continues to produce one of the most widely recognized and field-proven GPR system ranges available globally. GSSI’s GPR systems span applications from high-resolution concrete inspection to deep geological survey, with product lines including the SIR series control units, StructureScan Mini for concrete assessment, the Utility Scan for underground utility detection, and the SIR 4000 as a multi-channel capable field unit supporting a broad antenna frequency range. Each system is engineered around GSSI’s proprietary antenna designs and the SIR control platform, which manages pulse generation, signal digitization, real-time display, and data storage within a ruggedized field-deployable housing.

GSSI antenna options cover center frequencies from 16 MHz for deep geological and geotechnical surveys reaching depths of 30 meters or more in favorable conditions, through 200 MHz, 400 MHz, and 900 MHz for utility mapping and road assessment, up to 1.6 GHz and 2.6 GHz for near-surface concrete scanning at depths within 600mm. The RADAN software platform accompanying GSSI systems provides post-processing functions including signal gain adjustment, background removal, migration processing for hyperbola collapse, and depth slice generation for three-dimensional subsurface volume visualization.

In Pakistan, GSSI GPR systems are used by structural engineers, road condition survey teams, utility mapping contractors, forensic investigators, and military engineering units requiring a documented, globally supported GPR platform with established field performance records across diverse soil and structural conditions.

Tactical Supply Pakistan supplies GSSI ground penetrating radar systems, antennas, and accessories for professional subsurface survey operations across construction, infrastructure, security, and geophysical applications in Pakistan.
