When we choose the combined navigation products with different accuracies, we often need to consider multiple factors at the same time, including application scenarios, positioning accuracy requirements, cost budget, system stability and technical support. So far, ERICCO has the following three combined navigation products:
Mapping-level & Ultra-precision GNSS/MEMS INS——ER-GNSS/MINS-01（attitude up to 0.01°, post-processing 0.004°，heading 0.05°, post-processing 0.01°）
High-precision MEMS Integrated Navigation System——ER-GNSS/MINS-03（attitude up to 0.02°, post-processing 0.01°，heading 0.05°, post-processing 0.01°）
Cost-efficient GNSS aided MEMS INS——ER-GNSS/MINS-05（attitude up to 0.1°, post-processing 0.03°, heading 0.1°, post-processing 0.05°）
Next, I will use these three products to provide you with some suggestions on choosing integrated navigation products.
For some high-precision demand scenarios, such as surveying, drones, robots, etc., which require extremely high positioning accuracy, you should choose 01 or 03 series products. These products usually combine satellite navigation systems (such as GPS, Beidou, etc.) and inertial navigation systems (INS), and may be supplemented by other sensors (such as lidar) to achieve centimeter-level or even millimeter-level positioning accuracy.
For general precision demand scenarios, for general navigation and positioning requirements (such as ordinary car navigation), you can choose standard precision combined navigation products, such as the 05 series. These products can usually meet basic navigation and positioning requirements, and the price is relatively low.
Users can also choose suitable combined navigation products according to the positioning accuracy requirements of actual applications. For example, for self-driving cars that require sub-meter positioning accuracy, a high-precision positioning module that supports RTK (real-time dynamic carrier phase differential technology) should be selected. Users can choose between the 03 and 05 series according to their needs.
In addition, the cost budget should also be considered comprehensively when choosing. Under the premise of ensuring that the positioning accuracy requirements are met, try to choose products with high cost performance. In this case, the 03 series is generally chosen when considering the performance and price of the product.
In addition, our combined navigation products also provide multi-mode and multi-frequency support, support multiple satellite navigation systems (such as GPS, Beidou, Galileo, etc.) and multi-band, which improves the reliability and accuracy of positioning. Considering the subsequent use and maintenance, ERICCO also provides good technical support and after-sales service, so that users can get timely solutions when problems arise during use.
