LOKI is a sophisticated spoofer that provides real-time spoofing signal transmission, navigation bit prediction, GPS/Galileo spoofing and dynamic trajectory control.

LOKI The Ultimate GNSS Interference Generator/Simulator

At IGASPIN GmbH, we proudly present LOKI, your premier GNSS interference simulator and generator. This cutting-edge device, developed in Austria, offers unparalleled flexibility and power, all wrapped in an easy-to-use package. LOKI is your trusted ally for all things GNSS testing and research in interference attacks.

Key Features of LOKI:

  • Variety of interference simulation and generation.
    LOKI is your go-to solution for generating time-synchronized and -unsynchronized spoofing, meaconing, and various jamming techniques, including noise, sinusoidal, and chirp.
  • Multi-GNSS & Multi-Frequency Support:
    LOKI boasts compatibility with multiple GNSS systems and frequencies, ensuring comprehensive testing capabilities. Currently, GPS L1, Galileo E1, and GLONASS G1 are supported, and other services are under development.
  • Customizable Attack Parameters:
    With an intuitive graphical user interface (GUI), you have full control over attack parameters for tailored testing. This allows you to set up scenarios and configurations with ease.
  • Maps:
    Define victim receivers and spoofing trajectories via file uploads or integrated map applications including offline map, online map, and Google Maps.
  • No Need to Internet Connection:
    LOKI eliminates the need for internet access by sourcing ephemeris and Almanac information from its internal GNSS receiver, a crucial advantage for operations in communication-deprived environments.
  • Real-Time Location Adaptation:
    For precise synchronized spoofing, LOKI receives real-time location information from related sensors, ensuring reliable and accurate results.
  • Time Spoofing Flexibility:
    LOKI offers a unique GUI option to spoof the time, either into the past or future, for desired time lengths at the victim receiver. Test time-dependent systems with ease, such as power transmission, communications, and business transactions.
  • Explore Special Services:
    To enhance your testing experience further, IGASPIN GmbH provides special services tailored for researchers and students.
