ABSTRACT:
A test system and method for a marine vessel dynamic positioning system comprising a control system (2) arranged for receiving real measurement signals (7) from sensors (8) and for output of control signals (13) to actuators (16, 17, 18). The test system comprises a signal modifying computer (80) arranged for receiving real measurement signals (7), modifying the real measurement signals (7) into modified measurement signals (70) that depend on real values of the real measurement signals (7), and sending the modified measurement signals (70) to the control system (2), wherein the modified measurement signals (70) replaces the real measurement signals (7), so as for enabling testing of the control system (2) on errors represented by the modified measurement signals (70).
