QNX Software Systems' embedded operating system is being integrated into tactical radios used by the U.S. military, the company announced today.

The Ottawa-based company said Florida-based Harris Corp. is deploying the QNX Neutrino real-time operating system (RTOS) in the Harris Falcons III line of software-defined tactical radios (SDR).

"Other RTOS vendors may claim support for the SDR market, but as this announcement demonstrates, QNX leads the pack in successful, field-deployed, and certified SDR products," said QNX chief executive Dan Dodge in a statement. "In fact, the modularity and dynamically upgradable architecture of the QNX Neutrino RTOS makes it the perfect platform for SDR, providing the flexibility, scalability, and adaptability essential to any successful SDR implementation."

Harris said Neutrino's support for the industry-standard POSIX application programming interface was a central element in its choice of the QNX system, since POSIX is compliant with the software interoperability standard for the U.S. Department of Defense's joint tactical radio system (JTRS) program.
