Magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. They are used in INS to improve the attitude estimation for platforms such as UAVs (unmanned aerial vehicles), and can also aid navigation in GNSS-denied environments.
The article covers:
- Early magnetometer technologies
- The use of magnetometers in INS
- Applications of magnetometers, including LiDAR for construction site mapping, indirect georeferencing and GNSS-denied navigation
- 3D calibration for platforms that can operate in full heading, pitch and roll ranges
- 2D-2T calibration for applications where systems need to operate in full azimuth range but with limited range of pitch and roll angles
- 2D calibration for systems that operate in full azimuth range but with very small pitch and roll angles
- VG3D/on-the-fly calibration for objects such as drone payloads that can operate in full heading, pitch and roll ranges
Magnetometers are an essential component of high-performance inertial navigation systems, and Inertial Labs provides a wide variety of calibration methods for a range of applications. To find out more, read the full article here.
