public class AtoNReport

extends AISMessage

This message is used by stations mounted on an aid-to-navigation. The message is transmitted autonomously at a Rf of once every 3 min. This rate may be changed by an assigned mode command via the VHF link or by an external command.

Field Summary

int	dimension_ref_pos Reference point for reported position; Also indicates the dimension of ship in meters (See ITU-R M.1371-1 Figure 17 and 3.3.8.2.3.3)
int	latitude Latitude in 1/10000 min (±90 degress, North = postive, South = negative; 91 = (0x3412140) = not available = default
int	longitude Longitude in 1/10000 min (±180 degress, East = postive, West = negative; 181 = (0x6791AC0) = not available = default
int	mmsi_nb MMSI number
java.lang.String	name_of_aton Maximum 20 characters 6-bit ASCII @@@@@@@@@@@@@@@@@@@= not available = default
int	off_pos_ind For floating aids-to-navigation, only: 0 = on position; 1 = off position; NOTE - This flag should be considered valid by receiving station, if the aid-to-navigation is a floating aid, and if time stamp is equal to or below 59.
int	pos_accuracy 1 = High (<10 m; differential mode of e.g.
int	RAIM_flag RAIM flag of electronic position fixing device; 0 = RAIM not in use = default; 1 = RAIM in use)
int	res_for_regional_appls Reserved for definition by competent regional or local authority.
int	sensor_type 0 = Undefined (default); 1 = GPS, 2 = GLONASS, 3 = Combined GPS/GLONASS, 4 = Loran-C, 5 = Chayka, 6 = Integrated Navigation System, 7 = surveyed (base station) 8 - 15 = not used;
int	spare Not used.
int	timestamp UTC second when the report was generated (0-59, or 60 if time stamp is not available, which shall also be the default value, or 61 if positioning system is in manual input mode or 62 if positioning system operates in estimated (dead reckoning) mode, or 63 if positioning system is inoperative,).
int	type_of_aton 0 = not available = default; 1-15 = fixed aid-to-navigation; 16-13 = floting aid-to-navigation; refer to appropriate definition set up by IALA
