Lars Thrane LT-1000 and LT-500 Whitepaper Installation Report

We have made a short presentation illustrating an installation of a LT-1000 NRU and LT-500 AHRS on a Grand Banks 64 Aleutian, replacing an old Sperry Marine Satellite Compass.


The LT-1000 NRU and LT-500 AHRS are connected together on a NMEA 2000 backbone (to provide position and time to the LT-500 AHRS) and connected with NMEA 0183 to the external navigation equipment. The LT-1000 NRU is configured to 4800 baud, while the LT-500 AHRS is configured to 38400 baud.

The LT-1000 NRU and LT-500 AHRS are connected to the following navigation and communication equipment:

1)      Sperry Marine auto pilot – NAVIPILOT 4000
2)      Sperry Marine ECDIS (chart plotter & radar)
3)      SAILOR 6222 VHF
4)      Icom MF/HF
