LT-1000 NRU

The LT-1000 Navigation Reference Unit (NRU) is a maritime navigation product 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). 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 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.

LT-500 AHRS

The LT-500 Attitude Heading Reference System (AHRS) unit is a maritime navigation product 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 -25⁰C to +55⁰C (-13⁰F to +131⁰F).

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.

LT-300 GNSS

The LT-300 Global Navigation Satellite System (GNSS) receiver is a maritime navigation product from Lars Thrane A/S. The LT-300 GNSS receiver is designed for the leisure as well as the professional maritime markets. The LT-300 GNSS receiver meets all standards and certification requirements needed for worldwide maritime navigation equipment.
PERFORMANCE
The LT-300 GNSS receiver is capable of providing positions with an accuracy better than 2 meters. The LT-300 GNSS receiver outputs navigation data (up to 10 Hz): UTC time and date, position, course over ground, ground speed, GNSS satellite information and magnetic variation, in order to give your vessel smooth navigation capabilities. The 72-channel GNSS receiver benefits from advanced technologies such as:
• Receive and track multiple satellite systems (GPS & GLONASS, GPS & BeiDou, or GPS)
• Support for Satellite-Based Augmentation System (SBAS): EGNOS, WAAS, and MSAS
The LT-300 GNSS receiver is designed and built for the extremely 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-300 GNSS receiver is easy to mount on a 1” pole (optional installation: roof-mount) with a single cable supporting NMEA 0183, NMEA 2000, and power. The LT-300 GNSS receiver can be configured to either 4800 or 38400 baud (NMEA 0183), and open or short termination (NMEA 2000). An external PC installation and service software is available for optional configuration and maintenance of the LT-300 GNSS receiver.
