The U.S. Geological Survey awarded a purchase order to SBG Systems North America, Inc. for Qinertia Pro software on September 16, 2026, with a ceiling value of $10,000.00. Place of performance is La Crosse, Wisconsin. The order procures commercial navigation and post-processing software capable of integrating with Ping 3DSS sonar systems for hydroacoustic and hydrographic survey workflows. The software delivers tightly coupled GNSS/INS processing for GNSS-degraded riverine environments, direct interoperability with hydrographic platforms (HYPACK, Qinsy, CARIS), automated timestamp alignment across sensor streams, batch processing of multi-day survey datasets, and QA/QC reporting. The solution operates in secure computing environments without cloud-based processing and is compatible with existing inertial navigation units and GNSS receivers.
