The LT-300 Global Navigation Satellite System (GNSS) receiver is a maritime navigation product from Lars Thrane A/S. The LT-300 GNSS/GPS 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.

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 -40⁰C to +55⁰C (-40⁰F to +131⁰F).

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.

More than 40 years of experience have been put into the design and construction of the advanced LT-300 GNSS receiver, with an exceptional performance and specification level.
