Saab Unmanned Aerial Vehicle Relies on Integrity software

29th October 2008 - 06:19 GMT | by The Shephard News Team


BOSTON, MA, October 28 - EMBEDDED SYSTEMS CONFERENCE -- Green Hills Software, Inc., the technology leader in device software optimization (DSO) and real-time operating systems (RTOS), today announced that Saab is using Green Hills Software's INTEGRITY operating system in the Saab Skeldar unmanned aerial vehicle (UAV). Saab also selected Green Hills Software's MULTI debugger and the Green Hills Probe for use in the development of the UAV's redundant flight control unit, which was based on the Freescale MPC5554 microcontroller.

"We selected Green Hills Software because it provided the best toolset for the MPC5554, our chosen processor," commented Torbjörn Helgesson, system engineer, Computer System Architecture, Saab. "The project was jump-started thanks to the use of INTEGRITY, which quickly gave us a working base for the development. The integrated debugging and monitoring facilities within the operating system were particularly useful and the supplied board support package formed the basis for our own tailored BSP."

"Green Hills Software's operating systems and tools have been widely adopted in manned and unmanned aircraft in the civil and military sectors due to their proven reliability," said David Kleidermacher, chief technology officer, Green Hills Software. "We are pleased that Saab was able to accelerate its UAV project with the assistance of our kernel-aware probe and debugging tools."

About the Saab Skeldar

Saab's Skeldar is a fully autonomous, lightweight, unmanned helicopter. It can hover and perform vertical take-off and landing (VTOL) with a minimum of field preparation or additional equipment. The system is designed to support military as well as civil operations, national and international missions, and to operate during day and night. Potential applications include target acquisition and designation, surveillance, reconnaissance, and electronic warfare. Weighing 150kg, Skeldar has a maximum speed of 100km/h, 4-hour operating endurance and a range of up to 100km.

About the Green Hills Software INTEGRITY RTOS

Green Hills Software products have become the leading choice for the avionics industry. The INTEGRITY RTOS provides absolute reliability for embedded applications, allowing multiple applications to safely and securely operate on the same embedded computer. Memory partitioning prevents one application from accessing, stealing, or corrupting another application's memory or data. Time partitioning prevents a low criticality application from stealing CPU time away from high criticality applications on the same computer. Applications can be deployed at multiple safety levels and new applications can be seamlessly added over time.
