A Python library for decoding and encoding:
- AIS type 1/2/3 messages
- AIS type 5 messages
- AIS type 21 messages
- AIS type 24 part A and Part B messages (main craft case )
As there exist reliable and comprehensive python decoders, the emphasis is on encoding.
The bitstring Python library is a required dependency. You can get it here: https://pypi.python.org/pypi/bitstring
- Still need to implement the communication state bits. These bits are divided into three sections:
- bits 1-2 is the "sync state"
- bits 3-5 is the "slot time-out"
- bits 6-19 is the "sub message"
