Panbo: The Marine Electronics Weblog: SRT, blowing the AIS doors off
SRT, blowing the AIS doors offAug 17, 2009 In 2005, when Software Radio Technology talked about a Class B AIS transponder retailing for $500, I expressed some skepticism.  But "good work takes time" (as I often say about my home-built home), Class B has almost reached that price point in 2009 (largely thanks to SRT), and -- holy cow, Batman -- wait til you hear what they've got in the pipeline.  For starters, how about a small, high performance Class A transponder that will cost "well below $2,000" a...

AIS commstate
Main07.21.2009 17:04 AIS commstateI'm finally taking a look at the communication state that comes along with AIS. I've hacked my working version of noaadata to have a aismsg4handcoded.py that has hooks for the commstate.
