Product Description

The GCM-360 is a unique product for defining the magnetic field of the earth. This unit provides heading, GPS coordinates and sensor information. It includes a high accuracy triaxial fluxgate magnetometer and a triaxial accelerometer. This sensor is equipped with a dual antenna GPS system that provides heading data even when not in motion. This unit will output several data items including GPS true north heading, latitude, longitude, magnetic heading, X, Y, and Z axis magnetic field. An antenna spacing of 0.500 meters ±5mm is required. The “fore” antenna is placed 0.5 meter ahead of the “aft” antenna on a line parallel to the x axis of the sensor package.
