deuieii^^^nstrument^ Making Sense out of Motion... If your compass application involves vibration, acceleration, uneven terrain, or rough seas, you will find the Jewell Instruments ECG Series to be an uncompromising solution that will outperform rival units costing considerably more. The ECG provides remarkably accurate heading, pitch, and roll in dynamic conditions. It all starts with a precision 3-axis solid-state magnetometer. Two angular rate gyros independently stabilize pitch and roll. They augment 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 recommended applications for the ECG are manned and unmanned vehicles, robotics, weather buoys, antenna positioning, platform stabilization, marine navigation, excavation machinery, and irrigation equipment. The exceptional performance of the ECG is achieved by first calibrating all sensors over a wide temperature range. Then Jewell Instruments aligns the magnetic, tilt, and rate sensors to a common set of axes using precision calibration equipment capable of measuring angles as small as 0.001°. This alignment procedure, driven by our proprietary calibration routines, Features ♦ Exceptional Dynamic Performance ^ Heading within 3° typical for rates < 250 °/sec ^ Pitch and roll within 0.3° for rates < 250 °/sec ♦ High Static Accuracy ^ Heading within 0.5° or better ^ Tilt within 0.2° or better ♦ Wide Operating Range ^ ±42° Pitch and Roll ^ Local Hard Iron to ±1.5 Gauss ♦ Precise Calibration ^ Gyros calibrated for offset and gain from -40° to 85°C ^ Rate sensors calibrated and aligned to magnetometer and tilt sensor ^ Cross-axis error nearly eliminated on gyros and magnetometer ♦ Single Supply Operation ^ 6 to 45V unregulated DC or ^ Thermal overload and reverse polarity protection 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. The ECG comes with an enhanced version of Jewell's demonstration software that is backward compatible with the ECS and ECX. The magnetic calibration procedure required upon installation is identical, as are cabling and power requirements.
