The Jewell Instruments ECL Series eCompass is designed specifically for commercial, industrial, and military users. In standby mode, it draws only 50 microamps, and run mode requires only 15 milliamps. It provides accurate heading data in less than a tenth of a second from wake-up. An extended range tilt sensor is available that allows for ±60° of pitch and roll.

Other aspects of the ECL remain unchanged from the original ECS including its quick-connect, external serial interface. While the compass is in place, and without disconnecting system wiring, a serial cable or available USB cable can be temporarily connected via the RJ12-style modular jack. This allows easy access during installation for calibration and tuning. It also provides a valuable diagnostic port and can be used for an auxiliary read-out when needed. In situations where a fixed installation is not desirable, the RJ12 connection can be used exclusively.

User-definable parameters include the selection of NMEA output data and update rate; operating mode as continuous or query-only; and angle data in degrees, mils, radians, or 16-bit integer. Compensation for both hard and soft iron influences is built in.

Applications for the ECL Series eCompass include:

  • Unmanned vehicles
  • Robotics
  • Weather buoys
  • Antenna positioning
  • Marine navigation
