The DMS-EGP01 is used primarily in vehicle applications to integrate the features of a DMS-E604 and a velocity sensor into one unit. This sensor is equipped with a single GPS antenna that provides vehicle velocity data to the DMS. This data enhances the unit’s performance during highly dynamic maneuvers such as sharp turns and also makes this inertial gyro sensor a more complete system since it does not require velocity information to be supplied from an external sensor.

The DMS-EGP01 is typically used in automotive testing and vehicle dynamics applications. This sensor operates as an enhanced DMS-E604. The GPS antenna provides the DMS with a velocity signal, and also transmits heading data while in motion.
