Summary:The invention discloses a geomagnetic vector measurement system compensation method based on a three-dimensional Helmholtz coil. The method comprises the following steps: S01, constructing a geomagnetic vector measurement system interference magnetic field compensation model; s02, placing a geomagnetic vector measurement system in a central area of the three-dimensional Helmholtz coil, generating magnetic field data in different directions and with different sizes through the three-dimensional Helmholtz coil, and obtaining multiple groups of measurement data, the measurement data comprises an output value of the three-axis magnetic field sensor, a truth value generated by the three-dimensional Helmholtz coil and a change rate of the truth value generated by the three-dimensional Helmholtz coil along with time; s03, obtaining an error model equation set according to the data obtained in the step S02 and the interference magnetic field compensation model of the geomagnetic vector measurement system; and S04, so
