dAISy-catcher GPS add-on NMEA routers (vyacht) and RS-422This is an add on module for the dAISy catcher AIS receiver. When combined with a GNSS receiver, the dAISy catcher can report the time of arrival of AIS messages. This is currently considered an experimental feature as it is not widely supported by AIS software, but we think it may be of interest to security researchers. The add on is designed for use with an active GPS antenna. Antenna not included. See chapter 9 in the dAISy catcher manual for more
