Spirent introduces SimIQ to accelerate GNSS product evolution

(11 August 2020 - Spirent Federal Systems) Spirent Federal Systems today announced the release of SimIQ, a new software that will allow for earlier and more efficient GNSS testing during product development.

From software-in-the-loop through to final form testing, SimIQ enables developers to collaborate across the full design lifecycle through the creation, sharing and replay of I/Q data files.

SimIQ has been developed to meet the growing need to test GNSS capabilities earlier to accelerate product development, while simultaneously reducing costs by identifying issues prior to the purchase of hardware components. For developers using Spirent’s market-leading GSS9000 and GSS7000 simulators, SimIQ extends multi-frequency, multi-constellation simulation capabilities to cover software-only testing needs through the capture and replay of high fidelity I/Q data files. Housed in a single system, SimIQ reads and generates I/Q data with two major components, SimIQ Capture and SimIQ Replay.

SimIQ Capture - Allows Spirent GNSS simulators to generate I/Q files containing all the GNSS signal data required to test the algorithms, conformance, and performance of software receivers. It enables the recording of GNSS I/Q data into files hosted in the simulator, helping development and testing teams to validate positioning, navigation and timing (PNT) algorithms before expensive hardware designs.

SimIQ Replay - Enables the simulator to read any I/Q file containing GNSS data. In addition, it facilitates the generation of RF from pre-recorded interference signals and custom waveforms. The flexibility and unrivalled signal generation architecture of Spirent’s hardware enables the generation of these signals from I/Q files, while maintaining fidelity and quality due to Spirent’s unrivalled signal generation architecture.

Test engineers can accelerate development, and thus save time and resources by using Spirent simulators during the entire design lifecycle. The new software will bring significant benefits to developers in the defense and aerospace sectors.

Jen Smith, Spirent Federal Director of Business Development said, “SimIQ Capture allows developers to test their receiver algorithms in the earliest stages of design, minimizing costs and giving designers confidence as they proceed to the hardware design phase.”

SimIQ will be available to new and existing customers beginning in Q4 2020. For more information about Spirent’s SimIQ test capability for Spirent GNSS simulators, visit the SimIQ product page.
