Signal-to-Noise Ratio, the measurement of the received signal's strength related to the background noise comming into the loran receiver. Speed-Over-Ground, this is the calculated rate of movement of the vessel over the ground. Time Difference, refers to the elapsed time in microseconds between the arrival of the master and a secondary signal in a loran receiver. In loran, refers to the difference in degrees between "True North" and "Magnetic North. " Geographical destination defined in the loran memories as a Latitude/Longitude position. Cross-Track-Error, this is the calculated deviation from a track line drawn from the origination point to the destination waypoint retained in the loran's memory. MASTER MICROSECOND SECONDARY SNR SOG TD VARIATION WAYPOINT XTE SECTION II -INSTALLATION Although your Raynav 780 is designed to the highest levels of quality and performance, it can best attain those standards when a proper installation of the equipment has been achieved. This section provides the user with practical guidelines to assist in the planning and installation of the Raynav 780 aboard your vessel. 2. 1 UNPACKING AND INSPECTION Do use care when unpacking the unit from shipping carton to prevent damage to the contents. It is also good practice to save the carton and the interior packing material until the unit has been statisfactorily installed on the vessel. The original packing material should be used in the unlikely event that it is necessary to return the unit to the factory. [. . . ] should be fixed to both ends of coaxial cable.
