Open5066 - s5066d
Open5066 is an open source implementation of NATO NC3A STANAG 5066 protocol stack for HF radio communications. It aims to implement all of SIS (Annex A), DTS (Annex C), and some of the application layer (Annex F) functionality such as HMTP. Eventually Open5066 will also implement crypto module and may implement a softmodem for some waveforms such as S-4285 or S-4529, or it may evolve a smooth interface to integrate softmodems from other open source projects. Concrete embodiment of Open5066 is the s5066d daemon.
