Inertial Navigation Systems (INS) are fully autonomous navigation solutions that do not rely on external information and emit no detectable signals, widely applied in military and civilian aircraft, armored vehicles, guided weapons, fire control systems, and underwater equipment. Their key advantages include excellent stealth and immunity to electromagnetic interference, high continuity and low noise of navigation data, global and all-weather operational capability, rapid data update, and superior short-term accuracy and stability. These characteristics make INS a core technology component for precision navigation in complex environments.

During design verification, production assembly, factory acceptance, and maintenance phases, comprehensive performance testing of INS and its components is essential. Traditional testing methods, relying on manual operation or semi-automation, are inefficient, prone to human error, and difficult to standardize across testing environments. In mass production scenarios, these limitations further constrain productivity. Therefore, there is an urgent need for a fully automated test system capable of rapidly, efficiently, and reliably validating INS and component performance.

The HWA-SIVB-INS Inertial Navigation & Component Automated Test Solution provided by Walli supports comprehensive testing of inertial, fiber-optic, laser, and MEMS navigation systems and their components. The system can perform performance assessments in ambient, high/low temperature, and vibration screening scenarios, simulate different component configurations, and conduct batch testing of multiple devices and performance metrics. Automated display and report generation minimize human-induced errors, while manual testing functions allow validation under non-standard conditions and precise fault localization.

The HWA-SIVB-INS software platform consists of dedicated test cases and a general-purpose test environment, offering strong scalability. By selecting the corresponding product model, users can achieve one-click automated testing. A single test unit can support multiple product types, improving flexibility and efficiency for both laboratory and production line environments.

Hardware-wise, two form factors have been developed: rack-mounted and portable. The rack-mounted system is feature-rich, highly versatile, and easily expandable, suitable for comprehensive laboratory testing. The portable system is streamlined for field testing or mobile support scenarios, ideal for single product types or specific test missions. For instance, the HWA-FT-INS portable device supports automated testing of fiber-optic INS, strapdown INS, MEMS INS, accelerometer components, and rate gyro components.

In practical applications, Walli’s INS and component test systems have been validated in multiple scenarios. The fiber-optic strapdown INS ground test system evaluates functionality and performance and provides data for onboard fault analysis. MEMS INS test equipment enables product calibration, full-temperature static performance tests, and magnetic heading assessment. Flexible INS/attitude system two-line test devices assess performance and calibration for strapdown and combined navigation systems. Rate gyroscope testing ensures pre-installation performance validation and fault localization. Component automated test systems provide full-temperature performance assessment and standardized reports for INS and attitude system components.

The HWA-SIVB-INS Inertial Navigation & Component Automated Test Solution delivers a high degree of automation, extensive test coverage, and strong scalability. It offers a complete, reliable, and efficient technical support framework for the R&D, production, factory acceptance, and maintenance of inertial navigation systems and components, significantly improving testing efficiency, consistency, and quality assurance in complex navigation technology applications.
