The invention discloses a vector magnetic field sensor orthogonal error calibration device, which is provided with two Helmholtz coils which are concentrically arranged, are mounted on a device base and are adjustable in the left-right direction, and is used for generating a quantitative magnetic field environment. A lifting platform is designed in the middle of the device base, and an angle calibrator is mounted on the lifting platform; a vector magnetic field sensor is mounted on the calibration angle device; the vertical position of the vector magnetic field sensor is adjusted by the lifting platform, and the orientation of the vector magnetic field sensor and the direction of a magnetic field generated between the two Helmholtz coils are controlled by the calibration angle device to present a specified deviation angle. The vector magnetic field sensor is used for acquiring three-axis magnetic measurement data in different magnetic field environments, and correcting non-orthogonal errors of vector magnetic
