The Applied Physics Systems Model 545C heading sensor is a high performance, fully calibrated, narrow diameter heading sensor ideally suited for defense sonar array and marine seismic streamer applications.Read More
The Model 545C features a 3-axis fluxgate magnetometer, a 3-axis micro-machined accelerometer, and digital signal processing electronics. These are fully integrated in a small diameter pressure rated housing. The solid state strapdown configuration avoids the performance limitations of typical gimbaled systems and offers improved reliability.
The Model 545C digital signal processor samples and converts the internal sensor signals to 16-bit digital data and automatically compensates for any temperature and misalignment effects. Factory calibration of scale factor, bias, and misalignment angles is achieved by placing the instrument in high precision fixtures that apply rotational and magnetic fields. Scale factor and bias coefficients are measured over the operating temperature range of the sensor.
The Model 545C calculates roll, pitch, and azimuth angles and provides them on a bi-directional RS422 serial data link for data transfer rates of up to 9600 baud.
