The CHS series of high performance fully calibrated, small diameter heading sensors are ideally suited for towed sonar array and seismic streamer applications. The CHS heading sensor is a solid-state "strapdown" configuration that avoids the performance limitations of typical gimbaled systems and offers improved reliability. A 3-axis fluxgate magnetometer and 3-axis micro-machined accelerometer are combined with digital signal processing electronics and fully integrated within a small diameter pressure rated housing. The calculated roll, pitch, and azimuth angles are provided on a bidirectional serial data link that can be factory configured for RS232 or RS422 and is user programmable for data transfer rates of up to 9600 baud.
