The E-M controlled gyrocompass (Type DH-IIG) is a small type of gyrocompass adopting the technology of electromagnetic control and compensation. It can continuously and precisely indicate the ship's heading and determine the azimuth of measured objects. It is suitable for oceangoing vessels, naval service vessels and other types of vessels.
