The InterUSS Platform supports a range of UTM / U-Space services by facilitating communications between USSs and implements the Discovery and Synchronization Service (DSS) defined in the ASTM Remote ID standard. This includes two primary functions. First, it enables a USS to discover other USSs from which it needs to obtain information about flights and constraints in the airspace. Second, it provides mechanisms that require a USS to prove that it is aware of those flights and constraints. The InterUSS Platform accomplishes these functions without requiring any personally identifiable information and enables the USSs to share data only when necessary. The InterUSS platform was developed by industry in consultation with regulators and standards bodies around the world. It also provides a framework for interoperability in NASA’s UTM Technology Capability level demonstrations and the FAA’s UTM pilot program.
