The charm of combined navigation application: autonomous driving

With the development of science and technology, the application of combined navigation products has become more extensive. So what role does it generally play in the field of autonomous driving? Let's take a look!

1. Accurate positioning and map matching:

The combined navigation system provides positioning orientation and attitude information to the autonomous driving system, and then the autonomous driving system achieves high-precision vehicle positioning by integrating multiple sensor data (such as GPS, lidar, etc.) and map data.

2. Path planning and decision-making:

Combined navigation provides information to the autonomous driving system, and the autonomous driving system, combined with high-precision maps, can generate the best path to adapt to real-time road conditions and make corresponding planning decisions, such as lane keeping, lane changing, overtaking, etc.

3. Control and driving assistance:

The combined navigation system provides the autonomous driving system with real-time speed and attitude information of the vehicle, helping the autonomous driving system to make timely decisions to avoid possible collisions when obstacles are detected. At the same time, it can also provide real-time vehicle position, speed, attitude, and heading information when the autonomous driving system performs assisted driving, helping to achieve lane keeping, adaptive cruise and other functions.

For the above usage scenarios, please allow me to introduce ERICCO's combined navigation products to you.

Mapping-level & Ultra-precision GNSS/MEMS INS——ER-GNSS/MINS-01

The integrated navigation information provided by this product can reach 0.01° in attitude, 0.004° in post-processing, 0.05° in heading, and 0.01° in post-processing. The operating temperature of the product is -40℃ to +80℃, and it uses a highly reliable and high-precision MEMS gyroscope (bias instability <0.02°/h) and a large-range high-precision MEMS accelerometer (±60g, bias instability <2ug). High-precision MEMS Integrated Navigation System——ER-GNSS/MINS-03

The operating temperature of this product is consistent with the 01 series, the difference is that the gyroscope (bias instability <0.3°/h) and accelerometer (bias instability <5ug) used, as well as the output integrated navigation information (attitude up to 0.02°, post-processing 0.01°, heading 0.05°, post-processing 0.01°) are different.

Cost-efficient GNSS aided MEMS INS——ER-GNSS/MINS-05

This product focuses on cost-effectiveness. The attitude of the output combined navigation information can reach 0.1°, post-processing 0.03°, heading 0.1°, post-processing 0.05°, and the operating temperature remains the same as the above two products. High-reliability MEMS gyroscopes (bias instability <2°/h) and MEMS accelerometers (bias instability <24ug) are used.

In general, the main differences in the application of high-precision combined navigation products and ordinary combined navigation products are reflected in positioning accuracy, application scenarios, and the degree of integration of related technologies.
