LT-1000 NRU
The LT-1000 Navigation Reference Unit (NRU) is a maritime heading sensor with built-in GNSS/GPS receiver from Lars Thrane A/S. The LT-1000 NRU is designed for the leisure as well as the professional maritime markets. The LT-1000 unit meets all standards and certification requirements needed for worldwide maritime navigation equipment.
PERFORMANCE
The LT-1000 NRU is a small, compact, and very advanced unit with 12 precision sensors (magnetometers, gyros, accelerometers, barometer, thermometer, and GNSS/GPS receiver). With the use of sensor-fusion and Kalman filtering, the LT-1000 NRU outputs: true heading, roll, pitch, position, ground speed, course over ground, air pressure, and temperature in real-time, with high precision and resolution. The LT-1000 NRU 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.
- Receive and track multiple satellite systems (GPS, GPS & GLONASS, or GPS & BeiDou).
- Support for Satellite-Based Augmentation System (SBAS): EGNOS, WAAS and MSAS.
The LT-1000 NRU makes use of the latest technology within GNSS/GPS receivers, with market leading acquisition and tracking performance.
The LT-1000 NRU is designed and built for the demanding and rough environment at sea and with an operational temperature range from -40?C to +55?C (-40?F to +131?F).
INSTALLATION & NAVIGATION
The LT-1000 Navigation Reference Unit is easy to mount on a 1” pole (optional installation: roof mount) with a single cable supporting NMEA 0183, NMEA 2000, and power. The built-in magnetometer calibration algorithm will quickly compensate for heading deviation, and the LT-1000 NRU will output reliable navigation data. An external PC installation and service software is available for optional configuration and maintenance of the LT-1000 NRU.
More than 40 years of experience have been put into the design and construction of the advanced LT-1000 NRU, with an exceptional performance and specification level.
