Features:

• Outputs stable heading data accurate up to 0.75 degrees (RMS) or better at a fast rate even while the vessel stays stationary, in addition to submeter–accurate position information with differential corrections applied.
• Combination of a built–in gyro and tilt–sensor provides short start–up times and continual backup heading updates in the event of losing a GPS heading.
• COASTTM*1 technology allows old DGPS correction data to be utilized during a temporary loss (in excess of 40 minutes) of GPS signals without significantly degrading the data quality.
• SBAS–enabled, compatible with free, public satellite–based differential correction systems, including WAAS*2, EGNOS*3 and MSAS*4. IALA*5 beacon receiver optionally available.
• Requires only a single cable (power and data) connection and operates reliably over a varying power source voltage likely encountered in small vessels.
