US Air Force procures Orolia’s CRPA testing solution

February 15, 2022  - By

Orolia Defense & Security, provider of software-defined simulation solutions for navigation warfare, will supply a BroadSim Wavefront to the U.S. Air Force Guided Weapons Evaluation Facility (GWEF). BroadSim Wavefront is an innovative, Skydel-powered advanced GNSS simulator.

The GWEF provides laboratory testing and simulation tools for developing precision-guided weapon technology, including a comprehensive scope of GPS plus inertial navigation systems (INS) and integrated components such as sensors, signals of opportunity and controlled reception pattern antennas (CRPAs). CRPAs are fundamental in many platforms due to their enhanced protection against electronic attacks in NAVWAR environments.

The Broadsim Wavefront simulator will be integrated into a test environment for networked, collaborative and autonomous weapon systems being developed under the Golden Horde program. Golden Horde is one of four Air Force Vanguard programs designed to rapidly advance emerging weapons systems and warfighting concepts through prototype and experimentation.

Of the several capabilities the GWEF required, features such as low-latency hardware-in-the-loop, automated calibration, and the flexibility to quickly integrate future signals and sensors were the most critical and serve as a key reason Orolia’s BroadSim Wavefront was selected. The system will also be capable of testing eight-element CRPA systems, eight simultaneous fixed radiation pattern antenna systems (FRPA), or a combination of CRPA and FRPA systems.

“When designing BroadSim Wavefront, we re-imagined every aspect for the user,” said Tyler Hohman, director of products for Orolia Defense & Security. “Though the GWEF unit contains eight nodes (corresponding to each antenna element), it can be scaled from four to 16 antenna elements. One of the greatest advancements is our continuous phase monitoring and compensation technique. It automatically monitors, aligns and adjusts the phase of each RF output continuously throughout the duration of a scenario.”

“Gone are the days of re-calibrating each frequency on your system, limiting your scenario duration or re-calibration every time you power cycle your system,” Hohman said. “Simply turn the system on, start the scenario, and your Wavefront system phase aligns and remains aligned for the entirety of the test.”

Leveraging the Skydel Simulation Engine, BroadSim Wavefront also supports high-dynamics, MNSA M-code, alternative RF navigation, open-source inertial measurement unit (IMU) plug-ins and a 1000-Hz iteration update rate.

“Because of the software-defined architecture, many upgrades don’t require additional hardware, which has been a crucial advantage for customers who are already using this solution,” Hohman said.
