LT-1000 NRU

Product catalog summary

Introduction
The LT-1000 Navigation Reference Unit (NRU) by Lars Thrane A/S is a sophisticated 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 12 precision sensors including magnetometers, gyros, accelerometers, barometer, and thermometer.
Provides real-time data on true heading, roll, pitch, position, ground speed, course over ground, air pressure, and temperature.
Supports multiple satellite systems (GPS, GLONASS, BeiDou) with SBAS correction.
Simultaneous NMEA 0183 and NMEA 2000 data output.
Factory calibrated and tested over temperature ranges before shipment.

Performance
The LT-1000 NRU utilizes advanced technologies such as Kalman filtering and sensor-fusion to deliver high precision navigation data. It compensates for magnetic deviations and supports satellite-based augmentation systems like EGNOS, WAAS, and MSAS. The unit operates effectively in temperatures ranging from -40°C to +55°C.

Installation & Navigation
The unit is easy to install on a 1” pole or roof mount, with a single cable for NMEA 0183, NMEA 2000, and power. It includes a built-in magnetometer calibration algorithm for accurate heading data. Optional PC software is available for configuration and maintenance.

Specifications

Data accuracy: Heading accuracy is <0.5° static and <1.5° dynamic.
Position accuracy: GNSS <2.5 m, SBAS <2 m.
Operational temperature: -40°C to +55°C.
Waterproof rating: IPX6.
Power consumption: <1 W.

Certifications & Standards
The LT-1000 NRU complies with CE, IEC 60945, IEC 60950, EN 300 440, FCC, IC, RoHS, and supports NMEA 0183 and NMEA 2000 standards.

Accessories
Includes pole mount, optional roof mount, cables, and installation software. The unit comes with a 2-year warranty and requires no maintenance.
