Description
The DMS-SGP01 is a miniaturized version of the DMS-EGP01. To allow for a smaller package, this Dynamic Measurement System uses our S series MEMS rate gyro.
The DMS may be used in almost any application where triaxial angular rate and acceleration data is required. The sensor provides both angular rate and acceleration outputs in analog and digital formats. The DMS features six accelerometer outputs. The X, Y, and Z axis outputs represent the accelerations in the plane of the vehicle body, while the second set of three outputs measure the acceleration aligned with an earth-level coordinate system. This allows forward and lateral acceleration measurements that are essentially free of gravity influences. The triaxial sensor set allows software alignment of sensors, greatly reducing any alignment errors. The serial interface is highly configurable and provides access to almost all operational parameters.
The DMS-SGP01 is used primarily in vehicle applications to integrate the features of a DMS 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-SGP01 is useful in automotive testing, vehicle dynamics, and marine applications. This sensor operates as an enhanced DMS-S605. The GPS antenna provides the DMS with a velocity signal and also transmits heading data while the vehicle is in motion.
