Simxtract Bridges The Gap Between Field And Lab

SimXTRACT reshapes GNSS evaluation by channeling real-world intelligence, streamlining workflows and accelerating product development. GNSS, or Global Navigation Satellite System, is the umbrella term for satellite-based positioning systems that help devices determine location and time. GNSS signals are radio transmissions that carry precise timing and satellite orbit information, which receivers use to compute position by measuring how long signals take to travel from multiple satellites. Because these signals are extremely weak at the receiver and can be attenuated or blocked by buildings, foliage, and indoor materials—and can also be disrupted by RF noise, jamming, or spoofing—testing is important to confirm dependable positioning and timing behavior in the conditions products will actually face.Realistic GNSS testing works best when teams can combine true-to-life signal complexity with repeatable lab control, so edge cases surface early and fixes can be verified consistently.

Launch Overview: Testing With Real-World Insight

Spirent Communications, a Keysight Technologies company and a leader in testing and assurance for next-generation networks and devices, has introduced SimXTRACT, a GNSS test tool that establishes a new class for GNSS-enabled devices and systems. Built to close the divide between outdoor capture and laboratory simulation, the solution uniquely ingests live RF gathered in authentic environments, separates it into discrete components, and feeds fully controllable data into lab simulation for high-fidelity realism across every phase of the test cycle. Key capabilities include ingesting field-captured RF, decomposing signals into controllable elements, converting those elements into simulator-ready drive data for Spirent simulators, and enabling engineers to adjust and repeat scenarios without losing real-world nuance. In practical GNSS receiver tests, teams assess how a receiver acquires and tracks signals, maintains lock under motion, handles multipath and interference, and reports stable position and time across a wide range of operating conditions.

Executive View: GNSS Testing Benefits

SimXTRACT changes how teams validate positioning solutions. By fusing field-derived insight with controllable, repeatable lab simulation, customers no longer have to compromise on how they test in a fast-moving domain, said Peter Terry-Brown, Divisional CEO of Spirent’s Positioning business.Greater accuracy. Field-captured RF, converted into controllable simulator inputs, helps teams evaluate positioning and timing precision against realistic signal conditions while still enabling consistent lab repetition.Faster issue resolution. Decomposed signal components make it easier to isolate root causes, reproduce failures on demand, and verify fixes without waiting for the same field conditions to occur again.Shorter path to market. Repeatable scenarios reduce overall test cycles by supporting regression testing, parallel development across teams, and quicker iteration when requirements or firmware changes.

Unified Workflow: Field and Lab PNT Testing

Today, PNT developers typically choose between RF recording-and-playback or pure lab simulation to validate PNT systems and devices. Both methods matter in product development, yet neither alone delivers the richness of live signals alongside the control required for R&D, integrating receivers, or running regression suites. SimXTRACT unifies these approaches by transforming signals acquired in real environments into precisely decomposed elements and converting them into realistic simulator drive data for Spirent simulators, enabling fully controllable scenarios with real-world nuance. In this workflow, GNSS simulators provide a repeatable, controlled test environment where teams can vary satellite geometry, dynamics, and channel conditions to create consistent baselines, stress scenarios, and regression runs that are difficult to reproduce outdoors.
