NMEA Parser for Rust

NMEA Parser on crates.io NMEA Parser on docs.rs

This Rust crate aims to cover the most important AIS and GNSS NMEA 0183 sentences. It supports both class A and B types of AIS.

Usage

Include the following fragment in your Cargo.toml file:

[dependencies]
nmea-parser = "0.4.1"

The following sample program uses the crate to parse the given NMEA sentence and to print some fields of the resulting data object:

use nmea_parser::*;

let mut p = NmeaParser::new();
let sentences = vec![
  "!AIVDM,1,1,,A,H42O55i18tMET00000000000000,2*6D",
  "!AIVDM,1,1,,A,H42O55lti4hhhilD3nink000?050,0*40",
  "$GAGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*56",
];

for sentence in sentences {    
    match p.parse_sentence(sentence)? {
        ParsedSentence::VesselDynamicData(vdd) => {
            println!("MMSI:    {}",        vdd.mmsi);
            println!("Speed:   {:.1} kts", vdd.sog_knots.unwrap());
            println!("Heading: {}°",       vdd.heading_true.unwrap());
            println!("");
        },
        ParsedSentence::VesselStaticData(vds) => {
            println!("MMSI:  {}", vds.mmsi);
            println!("Flag:  {}", vds.country().unwrap());
            println!("Name:  {}", vds.name.unwrap());
            println!("Type:  {}", vds.ship_type);
            println!("");
        },
        ParsedSentence::Gga(gga) => {
            println!("Source:    {}",     gga.source);
            println!("Latitude:  {:.3}°", gga.latitude.unwrap());
            println!("Longitude: {:.3}°", gga.longitude.unwrap());
            println!("");
        },
        ParsedSentence::Rmc(rmc) => {
            println!("Source:  {}",        rmc.source);
            println!("Speed:   {:.1} kts", rmc.sog_knots.unwrap());
            println!("Bearing: {}°",       rmc.bearing.unwrap());
            println!("Time:    {}",        rmc.timestamp.unwrap());
            println!("");
        },
        _ => {
        }
    }
}

The program outputs the following lines:

MMSI:  271041815
Flag:  TR
Name:  PROGUY
Type:  passenger

Source:    Galileo
Latitude:  48.117°
Longitude: 11.517°

Features

The following features are included in the published version of the crate. Details about version history can be found from the changelog.

Feature Description
AIS sentences VDM/VDO types 1-3, 5, 18-19, 21, 24 and 27
GNSS sentences GGA, RMC, GSA, GSV, VTG, GLL
Satellite systems GPS, GLONASS, Galileo, BeiDou, NavIC and QZSS

Roadmap

Until version 1.0 refactoring and renaming of crate's code elements is likely to happen. The following table shows the plan to include different sentences in the crate. Prioritisation is based on estimated significance and implementation effort of each of them.

Version Category Goal
0.5 AIS VDM/VDO types 4, 9-17
0.6 GNSS ALM, DTM, GBS, HDT, ROT, STN, TRF, VBW, ZDA, XTC, XTE
0.7 AIS VDM/VDO types 20, 22, 23, 25, 26
0.8 AIS VDM/VDO types 6-8
1.0 general Stable API, optimizations, enhanced documentation
1.2 GNSS AAM, BOD, BWC, R00, RMB, RTE, WPL, ZTG
1.3 GNSS APB, RMA, GRS, GST, MSK, MSS, STN, VBW
