An error correction device 34 installed on a work vehicle to correct errors in measurements made by a sensor device having a GNSS sensor and a gyro sensor comprises a first acquisition unit 341 that acquires a velocity vector of the work vehicle measured by the GNSS sensor represented in a local coordinate system, and an angular velocity measured by the gyro sensor represented in a sensor coordinate system having three axes with respect to the sensor device, a second acquisition unit 343 that acquires a steering amount of the work vehicle, a set position determination unit 344 that determines a set position located at a different position from the sensor device's position in the sensor coordinate system based on the acquired amount of steering, and a velocity vector correction unit 347 that corrects the velocity vector of the work vehicle measured by the GNSS sensor by calculating the velocity vector of the work vehicle at the determined set position based on the velocity vector of the work vehicle at the measurement position and the acquired angular velocity.
