Azimuthtrue
Azimuthtrue is a term used in navigation and geospatial data processing to describe the process of converting an azimuth measured from a reference frame to the true azimuth relative to geographic north. In practical terms, Azimuthtrue refers both to the concept of producing true azimuth values and to a family of software tools and hardware modules designed to perform this conversion in real time. The approach combines data from GNSS receivers, inertial measurement units, and magnetometers with models of magnetic declination and grid convergence to produce azimuth outputs that are aligned with true north.
Core components include a declination model (to offset magnetic north), a regional convergence model (to account
Historically, the concept emerged in the early 2000s as navigation systems sought to improve accuracy in changing
