Spirent Products

Today’s greater emphasis on customer experience management means finding and resolving issues more quickly, preferably before your customers are even aware of them. Spirent develops innovative hardware and software solutions and test methodologies which help shorten customer product development cycle, improve the quality of services, whilst reducing cost and risk.

Satellite positioning has a rapidly widening range of applications – from military and intelligent transport systems to cameras, wearables, drones and tablets. But integrating a GPS or multi-GNSS receiver into a system – and verifying that the system works accurately everywhere—can be a challenge.

In developing the next generation of Global Navigation Satellite System (GNSS) services or devices and you need to deliver the best possible accuracy, availability, integrity, and performance, or verify that the system works accurately everywhere, then Spirent has the tools.

– Trusted by the world’s most demanding applications – now available for yours –

To develop positioning, navigation and timing systems for military, space, research and other high-precision applications you require sophisticated and highly comprehensive testing. The GSS9000 GPS/GNSS simulator is the ultimate GNSS/GPS test solution, giving the very best in performance, flexibility and capability of any GNSS test solution, anywhere.

The power and flexibility of the GSS9000 with SimGEN™ make it the fundamental platform on which many customised solutions can be built, from wavefront simulation for CRPA test to bespoke signal generation and manipulation for specialised requirements.

Accessible, flexible and modular configurations… the GSS7000 supports any combination of GPS/SBAS/QZSS, GLONASS, Galileo and BeiDou-2 signals, for testing all types of signals. Software, constellations and options can be added via easy, affordable in-field upgrades.

Up to 256 channels are supported across 4 frequency bands allowing full simultaneous simulation of all GNSS systems plus more than enough channels for rich multipath.

Choose from 4 software packages (SimTEST, SimREPLAY, SimREPLAYplus, or SimGEN) to suit different test requirements, applications and test budgets.

With a choice of 4, 8, 16 bit I/Q quantisation, and up to 50MHz recording bandwidth over multiple GNSS frequencies the GSS6450 is an ideal system for demanding test applications: from 4-bit GNSS chipset R&D, to interference and jamming analysis and high-end GNSS system test. Record up to 200MHz bandwidth of data, 4 GNSS frequency bands simultaneously.

Multipath and signal obscuration can cause significant error in GNSS receivers. Multipath errors can vary from a few metres to hundreds of metres, depending on satellite geometry and environmental conditions. Accounting for these occurrences is vital in most positioning, navigation, and timing solutions.

Sim3D is an innovative 3D modelling system that creates a realistic environment for the testing of multipath and obscuration effects. Simulated GNSS signals interact with fully customisable models and environments, giving a level of detail, control, and realism not available in other solutions.

Bring GNSS into dynamic HIL environments with Spirent’s dedicated software solution.

Spirent’s GNSS simulators are built to the highest standard, designed specifically for GNSS testing of market leading products. SimHIL enables users to integrate Spirent’s GNSS simulators with the industry’s leading hardware-in-the-loop platforms.

If you want to ensure your positioning devices work when exposed to fake or replayed GNSS signals then you need advanced testing tools. SimSAFE is a software application that interfaces with SimGEN™ to facilitate laboratory evaluation of GNSS receiver vulnerability to spoofing signals and the development of effective countermeasures.

Fast-track your inertial system testing.

Testing the full operational performance of GPS/inertial systems usually requires expensive and time-consuming field testing on an appropriate moving vehicle platform.

The SimINERTIAL system emulates inertial sensor outputs while concurrently simulating GPS RF signals, thereby enabling controlled, repeatable testing of integrated GPS and inertial units, and reducing the need for field trials.
