AIS Type 27 — Long Range Position Report.

ITU-R M.1371 bit layout (96 bits):

• bits 0–5: message type (= 27)
• bits 6–7: repeat indicator
• bits 8–37: MMSI (30 bits)
• bit 38: position accuracy
• bit 39: RAIM flag
• bits 40–43: navigational status (4 bits)
• bits 44–61: longitude in 1/10° (18 bits, signed)
• bits 62–78: latitude in 1/10° (17 bits, signed)
• bits 79–84: SOG in knots (6 bits, integer, 63 = not available)
• bits 85–93: COG in degrees (9 bits, integer, 511 = not available)
• bit 94: GNSS position status

Fields

mmsi: u32

position_accuracy: bool

High position accuracy (DGPS / differential fix).

raim: bool

RAIM (Receiver Autonomous Integrity Monitoring) flag.

nav_status: Option<NavigationStatus>

Navigational status. None if not defined.

longitude: Option<f64>

Longitude in decimal degrees WGS-84 (1/10° precision). None if sentinel (181°).

latitude: Option<f64>

Latitude in decimal degrees WGS-84 (1/10° precision). None if sentinel (91°).

sog: Option<u8>

Speed over ground in integer knots. None if not available (raw = 63).

cog: Option<u16>

Course over ground in integer degrees (0–359). None if not available (raw = 511).

gnss_position_status: bool

true = current GNSS position; false = not GNSS position (4 h old or more).

Trait Implementations

impl Clone for LongRangePosition

fn clone(&self) -> LongRangePosition

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LongRangePosition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LongRangePosition

fn eq(&self, other: &LongRangePosition) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
