GPS Anti-Jam and the Latest in Sensor Fusion Testing
Recorded on January 21, 2021

In this webinar, we will discuss the merger that formed Raytheon Technologies, the critical importance of GPS anti-jam solutions, new methods to interface non-GNSS sensors into a GNSS test suite, how precise time synchronization improves sensor use, and the latest in sensor fusion testing.

Raytheon Intelligence & Space

Join Chad Pillsbury and Ben Graham, senior director and deputy director, for Raytheon Intelligence & Space's Resilient Navigation and Reconnaissance Solutions business, as they discuss the merger of United Technologies and Raytheon Company to form Raytheon Technologies, as well as GPS anti-jam, sensors, artificial intelligence and time transfer.

  • Why GPS anti-jam solutions are of crucial importance to operating in GPS contested and denied environments;
  • Advantages of an optimized sensor suite and their benefit to the warfighter of today and tomorrow; and
  • How precise time synchronization improves sensor use, enables data link participation and grants access to a common operating picture network

Spirent Federal Systems

Roger Hart, Director of Engineering at Spirent Federal, discusses existing capabilities in the area of non-GNSS sensors and new product developments.

  • Introduction of an open source Ethernet protocol to simplify integration of new and existing sensors into a GNSS test suite

Spirent Communications

Ajay Vemuru, Product Manager at Spirent Communications, discusses sensor fusion testing using a simulation framework, including GNSS, IMU/INS, Baro, Compass, etc...

  • Value of simulating model specific error characteristics for each of the sensors;
  • How can realistic vehicle dynamics and trajectories be fed into the simulation framework; and
  • How we use cutting-edge ray tracing algorithms to add deterministic yet realistic multipath simulation to aid multipath mitigation

Improving Jamming and Spoofing Robustness with Multi-antenna GNSS Simulation
Recorded on November 18, 2020

In this webinar from Spirent, we will explore the challenges of reliably testing adaptive antennas and provide guidance on establishing test requirements.

We will then focus on the use of GNSS constellation simulators for the performance evaluation of advanced anti-jamming and anti-spoofing techniques of GNSS receivers using multiple antennas in an antenna array.

Topics covered
  • Characterizing an adaptive antenna
    • How adaptive antenna systems work
    • Challenges of testing adaptative antennas
    • Choosing a test method
  • Development of Array Receivers with Anti-Jamming and Anti-Spoofing Capabilities with Help of Multi-Antenna GNSS Signal Simulators
    • Motivations & development process
    • Overview of the multi-antenna GNSS constellation simulator test set up
    • Jamming and spoofing scenarios: results and conclusions
