An AIS slot is 26.66 ms long. The data modulation is 9600 bit/s, so each slot has a maximum capacity of 256 bits. The framing is derived from the HDLC standard, described in ISO/IEC 13239:2002. Each slot is structured as such: <8 bit ramp up><24 bit preamble><8 bit start flag><168 bit payload><16 bit CRC><8 bit stop flag><24 bit buffer>
