Asynchronous, multiplexing, single line transmission and recovery data system

Asynchronously multiplexed sample data sub-systems employ transmission over a single line to a remote synchronizer and demultiplexer. At the remote synchronizer, the data are recovered by synchronizing signals derived from the data itself. A sub-system, or satellite location, supplies continuously sampled binary data along with a satellite identification and synchronizing sequence as a satellite message frame. This information is supplied bit-serially, to a multiplexer junction. The multiplexed satellite information is delivered asynchronously onto a single line transmission channel with other like bit serial satellite message information from other satellite monitoring sites. Such satellite information is transmitted to a central collection and analysis site where it is demultiplexed according to the words and bits that make up a satellite message frame.
