MEET SimXTRACT

SimXTRACT is a groundbreaking GNSS test tool

SimXTRACT transforms how you develop, test, and debug PNT-enabled systems. By decomposing real-world GNSS IQ recordings into precise signal components, SimXTRACT bridges the gap between field and lab, letting you recreate realistic signal environments in a simulator — bringing unprecedented knowledge, realism, repeatability, and control to your test workflows.

​

In today's high-precision PNT ecosystem, testing with realistic signals is critical. SimXTRACT delivers what others can't: the power to extract real-world data, giving you the flexibility to investigate, manipulate, and control your real-world testing like never before.

Unprecedented realism in the lab

SimXTRACT performs signal decomposition on scenarios captured on record & playback devices, breaking down each received signal into discrete ray paths (line-of-sight and multipath) with metadata such as doppler offset, power level, and angle of arrival (AoA).

​

This decomposed environment is then converted into fully controllable simulation scenarios for Spirent simulators, reducing time spent in the field, cutting the cost and complexity of scenario capture and generation, and enabling repeatable, high-fidelity testing.

​

  • Combine the benefits of field and simulated testing

  • Modify, add, remove, or isolate signal components to diagnose edge cases

  • Save exponential time and money in field testing, recording capture, and scenario creation

  • Reduce data size from terabytes to megabytes for easy storage and sharing

Core capabilities

  • Captures and breaks down recorded I/Q into discrete signal paths

  • Supports GPS (L1, L2C, L5), Galileo (E1, E5a, E5b, E6); GLONASS, BeiDou, QZSS coming soon

  • Enables multipath, code error, power, and AoA analysis

  • Operates on PC or Spirent C50X

  • Outputs .scn test files for Spirent simulators (PNT X, GSS7000, PNT Xe)

Advanced signal analytics

Search decomposed data by:

​

  • Dilution of precision (DOP)

  • Satellites in view

  • Signal-to-noise ratio (SNR)

  • Signal type

  • And more

Why SimXTRACT?

  • Unparalleled realism: Simulation that reflects the real world.

  • Development efficiency: Diagnose bugs earlier, debug faster, avoid late re-engineering. Redress the balance between lab and field testing, saving time and money while generating more actionable data.

  • Field-to-lab workflows: Replay recorded scenarios in controlled, tunable settings.

  • Scalability: Expand test coverage using just one field capture.

Use case highlights

From initial R&D to final system validation, SimXTRACT streamlines development and enhances realism across every stage of your workflow.

Environmental Social & Governance (ESG)

Spirent's Positioning Technology business unit has been committed to ESG good practice and improvement since achieving ISO14001:2015 Environmental Management System certification in 2004.

ESG is a priority for Spirent across all aspects of our business, from sustainable buildings and sustainable product design to sustainable supply chain, manufacturing and shipping/export processes. As is best practice, we follow a continuous improvement process in respect of ESG.

Many of Spirent's test solutions rely on physical test equipment used in situ by our customers. We are working to reduce the lifecycle impacts of our products, and the environments in which they are used, in a number of ways:

​

  • Designing for environment and end of life, including compliance with all legal requirements

  • Reducing the size, weight, noise and power use of our products

  • Visualization and the development of Test-as-a-Service via PNT Professional Services

  • Improving utilization and automation

  • In-field servicing and upgrades

  • We use formal sustainability metrics in the product development process.
