LT-500 AHRS
The LT-500 Attitude Heading Reference System (AHRS) unit is a maritime navigation electronic compass / heading sensor from Lars Thrane A/S. The LT-500 AHRS unit is designed for the leisure as well as the professional maritime markets. The LT-500 unit meets all standards and certification requirements needed for worldwide maritime navigation equipment.
PERFORMANCE
The LT-500 AHRS unit is a small, compact, and very advanced unit with 11 precision sensors. With the use of sensor-fusion and Kalman filtering, the LT-500 AHRS unit outputs: true heading1, roll, pitch, air pressure, and temperature real-time, with high precision and resolution. The LT-500 AHRS unit includes advanced technologies such as :
- Kalman filtering.
- Calculation of magnetic variation based on the World Magnetic Model (WMM).
- Compensation of soft and hard iron (deviation).
- Built-in magnetometer calibration algorithm.
The LT-500 AHRS unit is designed and built for the demanding and rough environment at sea and with an operational temperature range from -25?C to +55?C (-13?F to +131?F).
INSTALLATION & NAVIGATION
The LT-500 AHRS unit is easy to mount and supports NMEA 0183, NMEA 2000, and power on a single cable. Without compromising the high performance, the LT-500 AHRS unit may be installed in any position. The LT-500 AHRS units has a built-in user interface (display and control buttons) for installation and service. Navigation output from the LT-500 AHRS unit is available in the user interface. The LT-500 AHRS unit supports automatic levelling (pitch and roll), which can be used during the installation. The built-in magnetometer calibration algorithm will compensate for deviation, and the LT-500 AHRS unit will output reliable navigation data. The external PC installation and service software is available for optional configuration and maintenance of the LT-500 AHRS unit.
More than 40 years of experience have been put into the design and construction of the advanced LT-500 AHRS unit, with an exceptional performance and specification level.
