Observator offers the widest range of display instruments, for local read out of meteorological parameters. The OMC-131 is a true and relative wind display which is suitable for 19"rack mounting and is used on many sea going vessels, ferries and FPSO's. The unit is capable of reading in two wind sensors, which is more a less a naval requirement having a port side and star board sensor. The sensor might be manual or automatically be selected. While reading in a (D)GPS signal the unit is capable of calculating and indicating true wind information at normal ship speeds. In case the gps signal is getting inaccurate the OMC-131 automatically switches over to Gyro and log.
