HMR3601 uPOINT miniature precision compass module

ETLG Inertial Aerosystemsvisit website

 

The HMR3601 uPOINT miniature precision compass module is a 3-axis digital compass system with gyro stabilisation to reduce effects of magnetic disturbances. Three magneto-resistive sensors, three MEMs accelerometers and a MEMS yaw rate gyro are combined to provide fully compensated compass heading as well as pitch and roll angles.

Honeywell Aerospace’s HMR3601 has provisions for hard and soft-iron correction algorithms to handle magnetic distortion effects. A World Magnetic Model feature is provided to automatically add declination angle corrections for reference to true north (geographic north). The yaw rate sensor provides temporary heading backup when the magnetic sensors are disturbed by the local presence of distorted magnetic fields.

Product features include:

  • 0.5 degree typical heading accuracy, 0.15 degree resolution
  • Power 3.75 to 5.5V DC, 300mW
  • 25Hz update rate
  • NMEA0183 HDG and HDT sentences, plus binary bi-directional packet data
  • Asynchronous RS-232 interface, 4800 to 38400bps
  • Compact in a 1” × 1.04” × 0.54” module
  • Designed for high mechanical shock tolerance

This product is also available as a demonstrator complete with display software and PC interface. Export Control Classification number 7A994 (non ITAR). For further information about the HMR3601 uPOINT miniature precision compass module please go to www.inertial.co.uk.
