Field Simulation

Outside the lab

In addition to industry-leading, lab-based positioning, navigation, and timing (PNT) simulation solutions, Spirent uniquely offers two field testing platforms that enable real, live-sky signals to be used in testing.

Portable Simulator

With Spirent’s Portable Simulator, the device under test (DUT) receives live-sky signals while additional signals are injected by the simulator—a ground-breaking innovation that creates a myriad of possible test cases for PNT resilience.

The field simulator can be provided with a built-in reference receiver and live-sky synchronization capability; different receiver types can be supported.


How badly are drones affected by GNSS spoofing? The Bundeswehr Technical and Airworthiness Center for Aircraft (WTD-61) attempts to find out using a Spirent Portable Simulator. Read the case study.

The Portable Simulator’s key features for government and defense users include

  • Spirent simulation capability from a significantly reduced form factor
  • Optionally with live-sky synchronization capability and rack-mount case
  • Dual-frequency, multi-constellation capable
  • Can be powered via mains or an external battery pack
  • Controlled either via external laptop or directly using remote commands

Record Live Sky

Record & Playback System (RPS)

The handheld form factor of the Spirent GSS6450 allows it to go anywhere you do, recording real-world signals with high dynamic range and wide frequency coverage for playback in the lab.

High bandwidth captures out-of-band and secure signals, and removable storage is ideal for a secure lab environment. The onboard spectrum analyzer ensures expensive and hard-to-repeat test cases are occurring as planned.

The GSS6450’s key features for government and defense end users include

  • High dynamic range for interference recording
  • Recording of other signals alongside GNSS, including complementary PNT and signals of opportunity such as wi-fi and cellular
  • Access to IQ data for post-processing analysis
  • Full control over gain (including AGC)
  • Designed for “Secure Room” requirements
    • No internal SSD (optional)
    • Built-in PC to enable user account logging
  • Real-time spectrum analyzer at both record and playback
  • Full remote control of the system
Webinar Navigation Warfare in the Field and Lab with guest speaker from U.S. Air Force

Field & Laboratory Navigation Warfare Simulation

Join us for an in-depth discussion on navigation warfare simulation from the U.S. Air Force’s 746th Test Squadron and Spirent as we consider NAVWAR testing in the field and lab, anomaly resolution, and the benefits of early testing in PNT system development. Paul Benshoof, technical director of the 746th Test Squadron, will discuss how simulation […]

Realism in GNSS Testing - Achievable with Spirent Federal

How to Bring Realism into Your GNSS Testing with RF Record & Playback

A record & playback system (RPS) is a key element of the professional GNSS tester’s toolbox. These portable devices allow engineers to make digital recordings of the real-world RF environment and replay them to test the performance of GNSS receivers in real conditions. Unlike the real world, this replay facility allows conditions to be repeated […]
