Abstract: The current TT&C software system of survey ship needs to complete the processing of data such as telemetry, remote control, tracking measurement, simulation of various aircrafts. The system is relatively complex and difficult to expand and maintain. SOA (Service Oriented Architecture) is a component model, which encapsulates different functional units of a complex system as services and rea- lizes the invocation of services through the interface, greatly reducing the complexity of the system and facilitating the expansion of system functions. This paper analyzes the TT&C software system of survey ship and designs the architecture of service-oriented TT&C service bus system of survey ship. The architecture supports two service scheduling modes: “service scheduling rules” and “service scheduling system”. The server, client and service scheduling system are implemented. The test results show that the system can guarantee the performance of service scheduling under two modes, which is of great significance to improve the efficiency of the TT&C software system of survey ship. 

Key words: SOA, survey ship, TT&, C software, TT&, C service bus
