In this chapter, an automatic dependent surveillance (ADS) application with fault tolerant property will be discussed. In narrow sense, fault-tolerant technologies guarantee continuous or uninterrupted operations of systems, units or devices under faulty conditions. In broader sense, fault-tolerant technologies guarantee to accomplish continuous or uninterrupted tasks under restricted conditions. An ADS technology for air-traffic radar systems accomplishes continuous or uninterrupted aircraft surveillance by sharing resources among radars with network. It guarantees safe and effective air-traffic operation in congested airspaces.
