Software Defined GNSS Simulator for Jamming & Navigation Warfare Testing

Software Defined GNSS Simulator for Jamming & Navigation Warfare Testing

Orolia has introduced a software-defined GNSS simulator to support advanced jamming, spoofing, and Navigation Warfare (NAVWAR) testing for battlefield readiness. Designed to test GNSS systems in an anechoic chamber, BroadSim is used to test CRPA/multi-element antennas, antenna electronics, applications with low dynamics, and entire PNT systems. BroadSim Wavefront tests the jamming/spoofing resiliency of CRPA and multi-element antenna electronic systems.

Today’s military forces rely on GPS for critical positioning, navigation, and timing (PNT) data in defense systems at the tactical edge. From Intelligence, Surveillance, and Reconnaissance (ISR) to communications and tracking, GPS receivers feed data to numerous downstream systems for situational awareness and command and control. When lives and mission success are at stake, warfighters need the assurance that GPS systems are tested and battlefield ready for continuous operations in contested environments.

Key features of this GNSS simulator:

  • Encrypted Signals: L1/L2 P(Y)-Code, L1/L2 AES M-Code, and L1/L2 MNSA.
  • Advanced PNT Sensor: IMU, wheel-tick, and barometer.
  • An unlimited number of interference signals can be generated with 1 RF output (within 80MHz bandwidth).
  • Jamming can be turned on and off through the SDX GUI and API.
  • Users can specify the location, power, antenna pattern, and modulation of jamming transmitters.
  • BroadSim will calculate the power received at the UUT based on the location and distance to the transmitter.
  • Enables users to create real-world threat scenarios to better support the warfighter.
  • Simulate multiple spoofers simultaneously.
  • Each spoofer can generate any GNSS signal.
  • Each spoofer has an independent trajectory and antenna pattern.
  • Skydel software automatically determines signal dynamics between each spoofer and receiver antenna.

Advanced Testing With Software-Defined Simulation

Orolia Defense & Security’s BroadSim product line was developed to simplify the creation of advanced jamming and spoofing scenarios with Navigation Warfare (NAVWAR) testing in mind. BroadSim supports high dynamics, jamming, spoofing, and encrypted military codes. Powered by Orolia’s Skydel simulation engine, BroadSim can simultaneously simulate multiple constellations including GPS, GLONASS, Galileo, Beidou, and QZSS. With high-performing hardware, a robust and innovative software engine, and an intuitive user interface, BroadSim is driving innovation in GNSS simulation, with technology that outperforms and exceeds typical features.

Revolutionary Performance at a Fraction of the Cost

BroadSim is revolutionizing the GNSS testing and simulation industry with its extraordinary flexibility, low cost, upgradability, and rapid development cycles. Leveraging the Skydel simulation engine and commercial-off-the-shelf (COTS) Software Defined Radios (SDRs), simulation of GNSS signals can be achieved at a fraction of the cost of today’s industry standards. The ability to generate military and multi-constellation signals on COTS hardware maximizes scalability, value, and time to market.

Simulate in the Lab to Perform with Confidence in the Field

Orolia’s simulation solutions deliver the confidence of knowing how your critical systems will perform across a wide variety of GPS/GNSS signal and PNT data limitations, outages, interference, and environmental factors.
