Method for compensating for accuracy errors of a hexapod, said hexapod comprising at least: - a fixed base; - an actuation assembly equipped with six independent, controllable linear translation actuators; - a control unit for the actuation assembly; and - a moveable carriage comprising a platform connected to the base by means of the actuation assembly, each of said actuators of the actuation assembly being linked by a first longitudinal extremity to the base by means of a first hinge and by a second longitudinal extremity to the carriage by means of a second hinge, said six actuators defining six pivot centres on the base and six pivot centres on the carriage, said method including: - a measurement step consisting in determining geometry and positioning errors on the hexapod, the measuring step including: • a first measurement sub-step consisting in measuring the positions of each of the pivot centres on the carriage and each of the pivot centres on the base, to determine positioning errors of the pivot centres, and of measuring the length of each of the actuators, to determine length errors of said actuators; and • a second measurement sub-step consisting in measuring positioning errors of each of the actuators along their path; and - a calculation step consisting in calculating, from the measurements made during the measurement step, error compensation values. characterised in that the first measurement sub-step includes: - a first individual sub-step consisting in measuring the positions of each of the pivot centres on the base, said first individual sub-step consisting in, to measure the positions of the pivot centres on the base: - fastening the balls onto the base at the position of the pivot centres; - fastening the base to a rectifier plate; and - measuring the position of the balls with the help of a 3D measurement device; and - a second individual sub-step consisting in measuring the positions of each of the pivot centres on the carriage, said second sub-step consisting in, to measure the positions of the pivot centres on the carriage: - fastening the balls to the carriage in the position of the pivot centres; - fastening the carriage to a rectifier plate; and - measuring the position of the balls with the aid of a 3D measurement device, and in that said method comprises an application step consisting in applying the error compensation values to the control unit of the hexapod, during use of the latter. - a fixed base;
