Action to be taken in case of GPS Failure :-

-
Inform Master. Switch over to GPS 2 (If fitted & working). Note down the last position obtained from GPS. Obtain the position of the vessel from Celestial or Terrestrial means . Increase the frequency of position fixing. Plot the position of the vessel in ECDIS. Inform VTS / Port Authority & Company Agent. Monitor the position of vessels in vicinity. Navigate the ship clear from any proximity to navigational hazard. Try to rectify the GPS by referring the GPS Manufacturers Manual. Keep a record of all events. Effect of GPS Failure:  ECDIS gives mandatory alarm & automatically switches over to DR mode.  Radar and ARPA switches to Relative motion. There are chances that Gyro may give an alarm, Since Gyro has latitude error and which needs GPS Sensor to correct the same. AIS will not transmit position of the vessel.

Both RADAR Failure (X Band & S Band) :  Inform Master. Reduce Speed of the vessel. Post extra lookouts. Do manual plotting by obtaining Bearing and Range of the target vessels from AIS. Monitor the position of the vessels in vicinity. Monitor the proximity to any danger to Navigation. Inform VTS / Port Authority & Company agent. DO NOT SWITCH ON NUC LIGHTS / SHAPES Pass at a safe distance from all Navigational Hazards by using PI (Parallel Indexing) in ECDIS. Broadcast SAFETY Message in VHF CH70(Alert) & CH 16.
