Spirent’s software-defined radio (SDR) design is flexible and customizable for future-proofed test capabilities, and field-upgradable simulators are designed to evolve with program needs.

New Portable Simulator for Range Testing. The new Portable Simulator from Spirent enables range testing with the ability to synchronize to live-sky signals for powerful in-field spoofing testing.

LEO PNT. Spirent is enabling next-generation positioning, navigation and timing (PNT) in low-Earth orbit (LEO); stay tuned for new signal capabilities in 2023. New SimORBIT provides enhanced orbit propagation for LEO satellites. Spirent Federal’s Alternative RF Navigation Simulator can generate alternative PNT signals individually or concurrently with GNSS signals.

Assure Autonomous Navigation. Forecast the operating environment with GNSS Foresight: know in advance when and where GNSS will be reliable.

Military, NAVWAR & Space. The GSS9000 Series multi-frequency, multi-GNSS RF constellation simulator is Spirent Federal’s most comprehensive simulation solution. It has an update rate of 2 kHz (0.5 ms), enabling ultra-high-dynamic simulations with accuracy and fidelity. The GSS9000 supports M-code, Y-code, alternative PNT, inertial and other non-GNSS sensors, and comes with advanced built-in jamming and spoofing.

CRPA Test System. Test antennas from 4 to 16 elements and beyond. More than 1,000 independent GNSS, jamming and spoofing signals can be generated/simulated across a phase-calibrated precise wavefront.

M-Code, RMP & Y-Code. SimMNSA simulates true M-code using MNSA-encrypted signals to create robust military GPS user equipment (MGUE) solutions and now includes Regional Military Protection (RMP) test capabilities. Y-code is also supported.

Inertial. Supporting the leading embedded GPS/inertial systems (EGI) and inertial measurement units (IMU), SimINERTIAL generates inertial sensor outputs, synchronous with simulated GNSS, to test integrated systems.

Anechoic Chamber Testing. Spirent Federal offers a patented “zoned chamber” approach for chamber-based CRPA testing that emulates the movement of satellites in orbit, enabling hours-longer test times and enhanced realism. Interference sources such as jammers and spoofers can be tested simultaneously, along with advanced multipath modeling.

Mid-Range Solutions. The GSS7000 multi-constellation simulator is an easy-to-use solution that can grow with users’ requirements. The GSS6450 RF record and playback system provides the realism and rich detail of real-world GNSS or complementary PNT signals in a handheld form factor.
