Field Detail

mmsi_nb

public int mmsi_nb

MMSI number of reporting unit.

nav_status

public int nav_status

0 = Under Way, 1= At Anchor, 2 = Not Under Command, 3 = Restricted Manoeuvrability, 4 = constrained by her draught, 5 = moored, 6 = aground, 7 = engaged in fishing, 8 = under way sailing, 9 = reserved for future use, 10 = reserved for future use, 11-14 = reserved for future use; default = 0

rot

public int rot

+/-127. (-128 (80 hex) indicates not available, which shall be the default). Coded by ROT[AIS]=4.733 SQRT(ROT[IND]) degrees/min ROT[IND] is the Rate of Turn (+/- 720 degrees per minute), as indicated by an external sensor. + 127 = turning right at 720 degrees per minute or higher; - 127 = turning left at 720 degrees per minute or higher.

SOG

public int SOG

Speed Over Ground in 1/10 knot steps (0-102.2 knots) . 1023 = not available, 1022 = 102.2 knots or higher.

pos_accuracy

public int pos_accuracy

1 = High (< 10m; e.g. Differential Mode of DGNSS receiver, or use of EUROFIX corrections); 0 = low (> 10m; Autonomous Mode of GNSS receiver or of other Electronic Position Fixing Device); Default = 0

longitude

public int longitude

Longitude in 1/10 000 minute ( 180 degrees, East = positive, West = negative. 181 degrees (6791AC0 hex) = not available = default)

latitude

public int latitude

Latitude in 1/10 000 minute ( 90 degrees, North = positive, South = negative. 91 degrees (3412140 hex) = not available = default)

COG

public int COG

Course Over Ground in 1/10 degree (0-3599). 3600 (E10 hex)= not available = default; 3601 - 4095 shall not be used

true_heading

public int true_heading

degrees (0-359) (511 indicates not available = default).

timestamp

public 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,).

public int res_for_regional_appls

[taken from spare] Reserved for definition by a competent regional authority. Shall be set to zero, if not used for any regional application. Regional applications shall not use zero.

spare

public int spare

Not used. Shall be set to zero.

RAIM_flag

public int RAIM_flag

RAIM flag of GPS device. 0= RAIM not in use = default; 1 = RAIM in use.

comm_state

public int comm_state

Communication state. Range 1-3
