Integrated navigation system on unmanned ships
The integrated navigation products we know are generally used in the fields of drones and surveying and mapping, but today I will introduce to you its application on unmanned ships. The application of integrated navigation products on unmanned ships is mainly reflected in the following aspects:
1. High-precision positioning: Through the information provided by the high-precision integrated navigation system, combined with information from various devices such as Doppler logger (DVL), high-precision positioning of unmanned ships can be achieved. This high-precision positioning is essential for unmanned ships to perform tasks such as maritime rescue, cruising, maritime supervision, pollution prevention monitoring, and marine waterway mapping.
2. Path planning and navigation: According to the preset navigation mission and terminal position, the combined navigation system can update the position and speed information of the ship in real time to ensure that the unmanned ship can navigate safely and accurately according to the predetermined path.
3. Autonomous obstacle avoidance: During the navigation of the unmanned ship, environmental perception equipment (such as radar, sonar, lidar, camera, etc.) can detect surrounding obstacles in real time through the information provided by the combined navigation system, and take corresponding obstacle avoidance measures to ensure the navigation safety of the unmanned ship.
4. Docking and recovery: For unmanned ships that need to be carried by mother ships and delivered to specific sea areas to perform tasks, the combined navigation system can assist in the autonomous recovery of unmanned ships. Through precise navigation and positioning, unmanned ships can accurately find the position of the mother ship and dock and recover with the mother ship.
For the above usage scenarios, I will introduce a combined navigation product to you.
Mapping-level & Ultra-precision GNSS/MEMS INS——ER-GNSS/MINS-01
The combined navigation information provided by this product can reach 0.01° attitude, 0.004° post-processing, 0.05° heading, and 0.01° 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). In addition, if the product occasionally loses lock during operation, it can still maintain normal operation for a short time.
If you want to achieve high-precision positioning when unmanned ships perform tasks such as maritime rescue, cruising, maritime supervision, pollution prevention monitoring, and marine channel mapping, and want unmanned ships to travel more safely and accurately according to preset navigation paths, and want unmanned ships to be able to take corresponding obstacle avoidance measures in a timely manner for obstacles on the navigation path, then you may wish to consider this surveying-grade ultra-high-precision combined navigation product - ER-GNSS/MINS-01.
