Key parameters
Measuring range
Heading full sphere; tilt ±90° pitch / ±180° roll; dip angle ±80°
Accuracy
Heading 0.1° rms static level (datasheet default filtering) / ±0.5° static tilt<35° dip<60° (product page); dynamic ±3.0° (rate limits apply); pitch/roll ±0.3° factory calibrated
Output
RS-232 or RS-485; NMEA 0183 and binary; continuous or sample modes
Supply
6–45 VDC unregulated (datasheet); product page also lists 7–45 VDC
Housing
ABS flame-retardant plastic UL94 V0 or die-cast aluminum Alloy 360.1
Ambient temperature
Operating −50 to +110 °C (datasheet) / −40 to +105 °C (product page; −20 °C with electrolytic tilt)
Fits full-attitude heading where you need a Jewell Instruments ECV Series eCompass—full-sphere heading with ±90° pitch / ±180° roll, 3-axis magnetometer plus gyro and accelerometer, heading 0.1° rms static/level (default filtering), and RS-232/RS-485 NMEA/binary output.
Key advantages
- Attitude — Full-sphere heading; ±90°/±180° tilt
- Heading — 0.1° rms static/level (default filtering)
- Sensors — Mag + gyro + accel (+ optional electrolytic tilt)
- Update — 27.5 measurements/s; 36 ms min
- Supply — 6–45 VDC class; ~40 mA run
Typical applications
- UAV / ROV heading modules.
- Full-attitude platforms.
- Industrial orientation.
