The Swift Navigation Binary Protocol (SBP) is a fast, simple, and minimal overhead binary protocol for communicating with Swift Navigation systems. It is the native binary protocol used by the Duro GNSS receivers to transmit solutions, observations, status and debugging messages, as well as receive commands and data from the host system, such as differential corrections and settings.
