GEOLOG Standard System

Single sensor dual axis GNSS speed log system

The GEOLOG is a satellite based replacement for a traditional ship’s Dual Axis log, calculating fore and aft and athwart ships ground speed in the direction of the ships heading.
The speed information is displayed on the X991 displays and may be distributed for use by RADAR and ECDIS, etc.

In addition to displaying and distributing the dual axis ground speed, the GEOLOG gives position, COG and SOG with accuracy better than standard GPS along with gyro heading and if available NMEA from the vessels EM/Speed LOG also speed through water.

The combination of GPS and GLONASS satellites achieves high accuracy measurement of speed. GEOLOG has the added advantage of being relatively unaffected by pitch and roll and suffers no issues from turbulence in the water such that found during use of thrusters or when being pushed/pulled by tugs.

In addition GEOLOG provides accurate position fixes from the sensor and distance run record for ground track.

Mean Velocity is better than +/- 0.01 knots 95% 0.03 knots
Position accuracy 95% better than +/-16 metre.
