1. Introduction QINSy (Quality Integrated Navigation System) is a modular, real-time, multi-purpose data acquisition and processing software suite. Developed by QPS, it is widely recognized as the gold standard for hydrographic surveying, offshore construction, and dredging operations. Unlike single-purpose software, QINSy is designed to handle any combination of sensors, vessels, and survey requirements within a single project environment. 2. Core Architecture & Workflow QINSy operates on a "Database-Centric" model. All survey data—raw sensor inputs, calibration parameters, processing settings, and final products—are stored in a centralized project database.
