wte-mt-rx-parser
This Rust crate aims to provide functionality for parsing messages generated by the WTE MT-RX-3 AIS, 406 + 121.5 alerting receivers. These receivers are designed to decode various types of emergency and maritime communication signals, including:
- 406MHz EPIRBs, PLBs and ELT beacons operating across the frequencies 406.020 to 406.045 MHz.
- AIS based SART alerting devices operating on both 161.975MHz and 162.025MHz.
- 121.5MHz or 243MHz man-overboard devices and emergency homing transmitters with the use of directional antennas.
Features
Provides simple parsing utilities for:
- 406 Message Serial Output
- MT protocol structured messages (
MT1UUUNNNTFHHHHHHHHHHHHHHHSS112233N4445566WYYYY
) - MT protocol raw messages (
MT6UUUNNNRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRYYYY
)
- MT protocol structured messages (
- Received Signal Strength (RSS) frequency / alerts (
SS,1,NNN<CR>
/SS,A,NNN<CR>
)
Notes:
- For parsing AIS messages (NMEA format), refer to other crates, such as nmea-parser.
- Refer to MT-RX-3 user manual for more information (#references).
