On December 17, 2022, the Intelligent New Application Sub-forum of the 2022 Greater Bay Area Automobile Innovation Conference hosted by the Guangdong Dawan District New Energy Automobile Industry Technology Innovation Alliance and Shenzhen Baoan District Smart Automobile Industry Technology Innovation Alliance will be held online + online The following combined form is grandly held. With the theme of "New Development Achievements of New Energy Vehicles and Responsibilities in the New Era", this conference will discuss hot issues such as new applications of intelligence, new development of three electric vehicles, new areas of low altitude, and new detection systems. Hu xiaobo, founder  of I-NAV Technology Co.,Ltd.   (referred to as "I-NAV") was invited to attend this conference and delivered a speech entitled "Hybrid Optical Fiber Inertial Navigation Solution Based on Advanced Intelligent Driving" "The wonderful sharing has attracted wide attention from the guests.

Hu xiaobo said in the sharing that there are currently two major pain points in the positioning of autonomous driving. One is position drift. In urban canyons, elevated environments, etc., satellite signals are blocked or interfered, which will cause the drift of the positioning point; the other is the inability to locate. It means that in areas without satellite signals (underground parking lots, tunnels, etc.), the positioning accuracy of the satellite guide is very low or even forms a positioning blind area, resulting in large errors. Due to the advantages and disadvantages of a single positioning scheme, in order to maximize the security of the system, satellite-habitual combined positioning (GNSS+RTK+IMU) is a widely used high-precision positioning scheme at this stage.

   At present, the MEMS inertial navigation commonly used in L3 smart driving cars has a gyro bias stability of about 10°/h. Less than 0.1°/h), MEMS gyroscopes cannot achieve such accuracy in the short term. Although the three-axis optical fiber IMU solution can meet the requirements of L4 for high-precision positioning, the cost is too high to meet the cost requirements of mass production and on-board vehicles. How to solve the pain point that the cost and accuracy of the vehicle-level integrated navigation and positioning system cannot be balanced has become a difficult problem facing the industry.

Hu xiaobo introduced that I-NAV will create the world's first car-grade hybrid fiber optic inertial navigation positioning system in 2022. This product uses a fiber optic gyroscope (zero bias stability less than 0.1°/h) in the Z-axis (car heading) to ensure high precision. The accuracy of the Z axis has been improved by nearly 100 times, and MEMS gyroscopes are used on the X and Y axes to ensure that the car is always driving on the predetermined track no matter what extreme road conditions it encounters during automatic driving, ensuring driving safety and filling the domestic car regulations. The blank area of cost and accuracy of fiber-optic hybrid inertial navigation system. This is a brand-new solution brought by I-NAV to the intelligent driving industry. At present, this product has entered the stage of on-board testing in many car companies and autonomous driving solution providers, and has been recognized by customers.

     At the end of the sharing, Hu xiaobo  introduced the basic situation of I-NAV to the guests. I-NAV was established on February 25, 2022. It is a high-tech company specializing in the research and development, production, sales and service of high-precision integrated navigation and positioning systems. Its products are widely used in autonomous driving, aerospace, robotics, agricultural wireless Humanization, construction machinery, rail transit, shipping and other fields, providing customers with flexible high-precision positioning and navigation services.

Hu xiaobo  pointed out that I-NAV has maintained a rapid development momentum since its establishment, and was successfully selected as "Shenzhen Innovation and Technology Committee Science and Technology Small and Medium-sized Enterprises". It has an industry-leading R&D team with high-level technical research and product design capabilities. With high-quality core device process technology and complete testing and verification capabilities, we have mastered all core technologies from key devices, inertial measurement units to integrated navigation systems, and can flexibly and fully meet customer customization needs. At the beginning of November, the company moved to a new location. The usable area has increased from 600 square meters to more than 3300 square meters now. The company has more complete functions and facilities. Center's high-precision positioning integrated solution.

Adhering to the mission of "deeply cultivating the field of space-time perception and leading the intelligent world with extreme high-precision positioning", all employees of I-NAV actively practice the core values of "hard work, simplicity and efficiency, ultimate innovation, and customer satisfaction", and continue to provide groundbreaking Products and solutions, and strive to realize the corporate vision of "serving every corner of the world with excellent high-precision positioning and making life better".
