    On May 25, 2025, the three-day 9th World UAV Conference successfully concluded at the Shenzhen Convention & Exhibition Center . The event brought together industry experts, enterprises, and scholars from over 100 countries and regions, featuring hundreds of discussions on topics such as UAVs and the low-altitude economy, as well as low-altitude infrastructure. CSSC Star&Inertia Technology emerged as a highlight of the exhibition with its self-developed navigation and perception products, offering innovative solutions for low-altitude flight safety and detection.     At the conference, CSSI made a strong appearance with a full-spectrum product portfolio, focusing on three core sectors: Inertial Navigation: Showcasing its proprietary achievements, including fiber-optic gyros, laser gyros, and high-precision inertial navigation systems. Intelligent Perception: Featuring breakthroughs in environmental sensing technologies, such as high-speed, fully domestically produced cameras and vision-based navigation systems. Emerging Navigation Technologies: Publicly debuting strategic products like celestial autonomous navigators, gravimeters, and Doppler wind radars. This comprehensive display not only demonstrated CSSI nearly two decades of expertise in precision instrument manufacturing but also highlighted its leadership in multi-source information fusion navigation algorithms.            Moving forward, CSSI will continue to focus on three core technological areas—high-precision inertial navigation, intelligent visual perception, and autonomous navigation for unmanned systems—accelerating technological iteration and product upgrades. By deepening collaborative innovation within the industry, the company will partner with leading domestic players to build an ecosystem for unmanned navigation technologies. It aims to overcome key technical challenges such as intelligent decision-making and environmental perception, providing systematic solutions for the global expansion of the UAV industry.

    At 17:00 on November 17, 2024, the 15th China Aerospace Expo ended successfully in Zhuhai. China Shipbuilding Star Inertia Technology is affiliated to the 717th Institute of China Shipbuilding Group Co., Ltd., a series of autonomous navigation products developed around unmanned platforms have attracted wide attention. 1,Series optical gyro products     As the core sensor of inertial autonomous navigation equipment, the optical gyroscope has been included in the core technology by CSSIT, and the technology has been passed down for 16 years. At present,CSSIT has launched a series of optical fiber gyroscope components, with common light source technology as the core, forming two types of gyroscope components, with spherical coverage of 20 to 120 types; and launched a series of laser gyroscope components, with embedded optical cavity design as the core, with spherical coverage of 40 to 120 types. 2,Series fully autonomous camera products     Fully autonomous cameras can not only serve as the core sensor for astronomical navigation and visual navigation, but can also be used in areas such as image tracking, video surveillance, and visual measurement. With more than 20 years of experience in research and development of astronomical navigation equipment, CSSIT focuses on the unique technical needs of visual navigation and astronomical navigation, and has developed in-depth camera algorithms, size, power consumption, environmental adaptability, etc., forming four fully autonomous camera product spectrums of ultra-high definition, ultra-high speed, high dynamics and high sensitivity. 3,Series of inertial autonomous navigation products     With the independent research and development advantages of optical gyroscope sensors, CSSIT starts in-depth design from the sensor level to ensure that the developed inertial autonomous navigation products have the best matching in terms of power consumption, heat dissipation, size, performance, etc., and meet the user experience of unmanned platform users in all aspects. The weight of the serialized inertial autonomous navigation product ranges from 500g to 10kg, and the autonomous navigation maintains capacity from 5 minutes to 48 hours, adapted to various satellite navigation denial environments. 4,Other autonomous navigation products     With years of experience in the field of autonomous navigation, CSSIT has continuously explored new autonomous navigation solutions. For the drone platform, the integrated astronomical autonomous navigation device and visual navigation developed by China Shipbuilding Star Inertia provides a more comprehensive autonomous navigation solution for drone navigation and control.     CSSIT will continue to deepen its efforts in the field of independent navigation, constantly explore new technologies, break through itself, and continue to launch more competitive products and solutions to provide users with safer and more reliable navigation products and services.

The INS is initially provided with its position and velocity from another source (a human operator, a GPS satellite receiver, etc.) accompanied with the initial orientation and thereafter computes its own updated position and velocity by integrating information received from the motion sensors.   INS is self-contained and does not rely on external signals. This independence makes it highly reliable in environments where GPS signals might be weak or unavailable, such as underwater, underground, or in space.

TYLXXC is an autonomous positioning highest accuracy inertial guide equipment equipped with unmanned submarines. It overcomes the problem of laser gyroscope jitter noise. The underwater radiation noise is extremely low, close to the underwater background noise. This model has been applied to multiple platforms of Chinese ships.   What is INS in GNSS? An Inertial Navigation System (INS) is a system that is used to compute relative position over time from rotation and acceleration information provided by an Inertial Measurement Unit (IMU). An INS uses the measurements from the IMU to provide position, velocity and attitude (roll, pitch and azimuth) calculations. Inertial Navigation System (INS) provides reliable position and orientation data even in the absence of GPS signals. Maritime Navigation: Ships and submarines use INS for navigation and control, particularly when operating underwater or in environments where GPS signals are unavailable.   An INS often receives data from a global navigation satellite system (GNSS) receiver and fuses it with data from the IMU to provide information to the host computer about the platform's absolute position (latitude, longitude, and altitude) and attitude (roll, pitch, and heading).

    Since 2022, the main inertial guide of the fixed wing platform has been developed in conjunction with the Zongheng UAV, and the TYF71A embedded fiber gyro inertial guide has been selected. It has passed the identification and has obtained small batch orders. The platform mainly aims at the international foreign trade market and is benchmarked against Turkey's "TB-2" type. The aircraft pursues the ultimate lift-drag ratio and high cost-effectiveness.     The TYF41A, TYF61A, and TYF71A series fiber inertial guides have been adapted to multiple models, with nearly 300 sets delivered in total, and the cumulative safe flight time has exceeded 10,000h.   What is the difference between IMU and INS? The IMU is a device for measuring angular velocity and acceleration, and the INS is to determine the movement of the moving carrier in the inertial reference coordinates through the measured angular velocity and acceleration values.

    The optical aerial attitude reference can provide artillery with high-precision azimuth and pitch angle information in real time in the field or in environments where external auxiliary sources are limited, ensuring that the artillery can accurately aim under various combat conditions, and synchronously output high-frequency and high-precision angular velocity information, supporting the rapid and stable artillery rotation response. Our series of optical inertial guides are adapted to various types of artillery systems, among which TYL50A and TYF71A are successfully used.   This Attitude and Heading Reference System is comprised of a three-axis Inertial Measurement Unit that is connected to a virtual three-axis sensor and a 3-axis magnetic sensor for measuring the pitch, heading (yaw), and the roll angle while the object is moving in a 3D space.   ADC, or Air Data Computer, relates to atmospheric data for flight performance, while AHRS, or Attitude and Heading Reference System, monitors the aircraft's orientation and direction.
