Versatile Inertial Navigation and Fiber Optic Gyroscope Test System

Product Description

High-precision three-axis motion simulator - Inertial Measurement Unit (IMU) and gyroscope test platform

The HY-INS3-550C is a core testing device designed specifically for the research, calibration, and performance verification of high-end inertial sensors. By simulating complex multidimensional angular motions in the real world, it provides a reliable and controllable benchmark environment for evaluating the static and dynamic performance of inertial devices.

Deepening Core Advantages

1. Superior Test Confidence
Metrological Traceability and Reference Transfer Capability: This simulator is not only a motion generator but also a "reference source" for precise angular motion parameters. Every angular rate and angle value it outputs can be traced back to international/national basic physical quantity standards through rigorous internal and external metrology chains. This ensures that any test data obtained on this platform has recognized authority and comparability, a fundamental prerequisite for product performance certification and conformity determination.

Data Consistency and Repeatability: With ultra-low shaft rotation error and high stability of servo control, the equipment can produce almost identical motion outputs under the same commands. This exceptional repeatability allows R&D personnel to effectively separate "product performance variations" from "noise introduced by the test equipment," thereby accurately locating problems, verifying the effectiveness of design iterations, and greatly shortening the R&D cycle.

Full Lifecycle Performance Guarantee: From core bearings and encoders to the control system, long-life, low-drift designs and components are used. With periodic self-calibration and health diagnostics, the equipment ensures that its accuracy remains within the factory tolerance range even after several years of use, providing sustained and reliable support for customers' long-term R&D and production activities.

2. Wide Range of Application Adaptability
Multi-dimensional Environmental Stress Composite Simulation: Breaking through the limitations of single-motion testing, it constructs composite test scenarios that closely approximate real-world application environments by organically combining "dynamic motion" with "static/dynamic temperature fields." Users can programmatically execute complex profiles such as "high-temperature high-speed rotation" or "low-temperature slow oscillation," exposing potential defects and coupling errors of sensors under cross-stress in a single test.
Expanding Application Boundaries: Its wide temperature range and high precision extend its application scope from conventional commercial and industrial fields to cutting-edge fields such as testing of near-Earth orbit satellite components, verification of polar scientific research equipment, and ground simulation of deep space exploration instruments, where reliability requirements are extremely high.
Future Scalability Framework: The platform adopts a modular design concept; the currently integrated temperature control chamber is only one of the standard configurations. Its mechanical interfaces and electrical architecture are designed for future expansion, allowing for seamless integration with vibration tables, vacuum chambers, or humidity control systems to upgrade it into a more comprehensive "multiphysics simulation test center."

3. Strong Versatility and Reliability
Extensive Load Compatibility: The UOT frame structure provides an open and robust installation space. Combined with flexibly configurable fixture interfaces, it can safely and conveniently support test units of various sizes, shapes, and weights, ranging from micro-MEMS chips to large integrated navigation systems, achieving multi-purpose functionality and maximizing investment efficiency.
Industrial-Grade Robustness and Maintenance-Free Operation: Designed according to industrial durability standards, key transmission components feature sealed and long-lasting lubrication designs, maintaining their condition under high-intensity, continuous testing tasks. An intelligent monitoring system can warn of potential faults, minimizing unplanned downtime and ensuring the efficient operation of production lines or R&D projects.
Clean testing environment guarantee: Comprehensive electromagnetic shielding (EMI) and radio frequency interference (RFI) suppression design effectively isolates external power grid noise and electromagnetic pollution generated by the device's own driver, providing an "electrically quiet zone" for high-sensitivity, weak-signal inertial sensors (such as optical gyroscopes) and ensuring the accuracy of measurement signals.

Key Features Expanded

1. High-Precision Motion and Measurement System
Nanometer-Level Motion Control Art: The servo control system employs feedforward compensation and adaptive filtering algorithms to pre-compensate nonlinear friction and inertial disturbances in the mechanical system. This achieves smooth, creep-free, and overshoot-free precise motion from near-stationary extremely low speeds (<0.001°/s) to high-speed rotation, with extremely low dynamic tracking error.
End-to-End Precision Closed-Loop: Angle measurement does not rely on motor feedback but uses an independent photoelectric encoder or circular grating system that directly reads the shaft angle as the position reference, forming a fully closed-loop control. This "direct measurement" method avoids the influence of transmission chain errors, achieving true angular position "definition" rather than just "execution."
Multi-Dimensional Synchronization and Real-Time Performance: The three-axis motion control card is based on a high-performance real-time operating system, ensuring microsecond-level synchronization and deterministic response of three-axis trajectory commands. This is crucial for multi-axis linkage simulations requiring precise phase relationships (such as simulating aircraft roll maneuvers).

2. Three-Axis Integrated UOT Structure Design
Unlimited Continuous Rotation Capability: Carefully designed conductive slip rings and fluid rotary joints (if required) enable the inner frame (T-axis) to achieve unlimited continuous rotation, perfectly meeting the needs of applications requiring long-term unidirectional rotation, such as gyroscope scaling factor testing and north-finding instrument calibration, without the worry of cable entanglement.
Excellent Axis Orthogonality and Perpendicularity: Through ultra-precision machining and assembly processes, the three-axis rotation axes maintain extremely high orthogonality under both static and dynamic loads. Low axis errors mean purer single-axis motion excitation and more accurate multi-axis motion synthesis, providing the fundamental physical guarantee for generating reliable test data.
Low-Interference Mechanical Environment: The structure is optimized through finite element analysis and possesses extremely high natural frequencies, effectively suppressing minor jitter and resonance generated during motion start-up, shutdown, or reversal, providing a "quiet" mechanical base for the device under test.

3. Integrated Environmental Simulation Chamber
Fast and Uniform Temperature Field Control: Utilizing an efficient heat exchange design and a multi-zone fluid circulation system, the chamber minimizes temperature gradients and allows for rd heating and cooling at programmed rates. This not only tests the temperature characteristics of sensors but also evaluates their transient response performance under high temperature fluctuations.
Fully Transparent Environmental Parameter Monitoring: The chamber integrates multiple temperature and humidity sensors (if supported), with data recorded synchronously with the motion control platform. Users can clearly analyze the real-time correlation between inertial device output changes and temperature fluctuations, providing a complete data chain for building accurate temperature compensation models.
Safe and Convenient Access Design: The chamber is equipped with observation windows and electrical and signal access ports, ensuring environmental isolation while allowing users to easily observe the status of the device under test in real time and provide power and high-speed data communication.

4. User-Friendly Control System
Graphical Programming and Simulation: The software supports drag-and-drop generation of motion trajectories (sine, trigonometric, custom functions, etc.) and can perform 3D motion simulations in advance to avoid physical collisions. Complex multi-axis coupling test programs can be completed as easily as building a flowchart. Data Management and Intelligent Analysis: The system automatically stores motion command values, actual axis position/rate feedback, temperature control data, and output data of the test piece in a unified, time-synchronized manner. The built-in data analysis toolkit can calculate key indicators such as zero-bias stability, scaling factor nonlinearity, and Allen variance with a single click, and generate standardized test reports.
Remote Monitoring and Automation Integration: Supports network-based remote operation and status monitoring, and provides standardized communication interfaces (such as TCP/IP and ), easily integrating into factory automated testing lines or enterprise product data management (PDM) systems to achieve unattended automated batch testing.

Main Applications
