LT-500 AHRS

Product catalog summary

Introduction
The LT-500 Attitude Heading Reference System (AHRS) by Lars Thrane A/S is a maritime navigation device designed for both leisure and professional maritime markets. It meets global maritime certification standards and is built to withstand harsh sea environments.

Key Features

Equipped with 11 precision sensors for true heading, magnetic heading, roll, pitch, air pressure, and temperature.
Supports simultaneous NMEA 0183 and NMEA 2000 data outputs.
Configurable NMEA 2000 termination resistor and NMEA 0183 data rate.
Factory calibrated and tested over temperature ranges.

Performance
The LT-500 uses sensor-fusion and Kalman filtering to provide real-time, high-precision navigation data. It includes technologies for magnetic variation calculation, deviation compensation, and magnetometer calibration. The operational temperature range is from -25°C to +55°C.

Installation and Navigation
The unit is easy to install in any position without performance loss. It features a user interface for installation and service, supports automatic leveling, and provides reliable navigation data. External software is available for configuration and maintenance.

Specifications

Data accuracy: Static heading accuracy < 0.5° (rms), dynamic < 1.5° (rms).
Communication: 8-pin connector for NMEA 0183, NMEA 2000, and power.
Power: Input voltage 9-40 VDC, power consumption < 1 W.
Environmental: Waterproof rating IPX3, operational vibration and shock resistance.

Certifications and Standards
The LT-500 complies with CE, IEC 60945, IEC 60950, FCC, IC, and RoHS standards. It is classified as protected equipment according to IEC 60945.
