LORAN TD Setup If the active GRI Chain, secondary stations, or offsets were changed since the waypoint was created, the waypoint now references the active GRI chain and secondary stations and adjust the TD coordinates accordingly. Remember that the GPS is not relying on the LORAN signal for navigation and actually converts the TD coordinate to a useful latitude and longitude coordinate before storing the waypoint to memory or using it for navigation. Because of this, the unit can navigate to a TD coordinate anywhere in the world. You must know your GRI chain number and/or secondary stations to create a LORAN TD location.
