The Jewell Instruments ECG Series eCompass provides remarkably accurate heading, pitch, and roll in dynamic conditions. The ECG features a precision 3-axis solid-state magnetometer; two angular rate gyros that independently stabilize pitch and roll; and a dual-axis, electrolytic tilt sensor that provides precise tilt measurements in static environments. Two sets of independent filters, one set for pitch and one for roll, combine gyro and electrolytic sensor measurements to provide the best available tilt measurements.

The performance of the ECG is achieved by first calibrating all sensors over a wide temperature range. Then the magnetic, tilt, and rate sensors are aligned to a common set of axes using precision calibration equipment capable of measuring angles as small as 0.001º. This alignment procedure minimizes axis coupling and corrects for gyro drift errors.

The ECG is compatible with Jewell's ECS and ECX series. The ECG board fits in the same enclosure and has the same mounting hole pattern and connectors. Identical NMEA sentences are available, and the ECG version includes additional binary data output for temperature and diagnostics.
