Real-Time Innovations (RTI) in San Jose, Calif., is providing its real-time messaging middleware to Insitu Inc. in Bingen, Wash., for long-endurance, unmanned aerial vehicles (UAVs). RTI’s technology will be used in Insitu’s next generation of UAVs, including the company’s ScanEagle and newer platforms. Insitu is using RTI Data Distribution Service in the ground control stations (GCSs) and in future air-to-ground communications. RTI connects the flight computers, sensors and on-board application computers. Within the GCS, RTI connects the systems that decode data feeds, analyze the UAV’s situation and interface to the operator control. Insitu’s newly designed distributed software architecture allows developers to put much more intelligence on the airplane. The design leverages RTI’s message bus to implement a hierarchical control network with well controlled data-flows. The information flow is much more orchestrated and flexible than in Insitu’s previous designs. For more information, contact RTI online at www.rti.com.
