According to foreign media reports, startup SBQuantum (SBQ) is trying to change navigation methods in areas where GPS is not available.
The company focuses on the development and sales of diamond-based quantum magnetometers for use in industrial and academic fields, especially autonomous vehicles.
The goal is to improve the accuracy and reliability of navigation systems, as well as revolutionize the detection of magnetic anomalies by more accurately identifying flaws in hidden environmental structures.
In complex and difficult conditions such as cities and other extreme areas that have not been surveyed, this technology will play its greatest role.
, Diamond-based quantum magnetometer (Photo source: Element Six), Target Applications,SBQ is building a total service solution that combines a sensor and client-specific dashboards for navigation and anomaly detection.
, Navigation, current GPS systems work by connecting to satellites.
When high-precision geolocation is needed, such equipment may use auxiliary signals such as real-time dynamic signals (RTK), which are highly susceptible to the surrounding environment.
, In addition, GPS systems can be supplemented by very accurate magnetometers that rely on the direction, strength and relative changes of a specific Earth’s magnetic field to provide precise position, altitude and heading information.
However, large metal structures such as skyscrapers may cause more serious interference with such magnetometers.
Due to the unique magnetic field line profiles of polar regions such as the North Pole, such systems will not be able to operate independently, often resulting in loss or damage to valuable equipment.
, In many cases, such as underground or underwater, GPS signals cannot reach them.
As a result, in such more challenging environments, where GPS is not available, autonomous vehicles such as drone distribution systems use high-precision magnetometers to navigate.
However, current solutions often have drift problems, which reduces navigation accuracy.
