Powerful, Adaptable Tools

R&D teams need testing systems as flexible and powerful as their imaginations – if their tools aren’t fit for purpose, they can lose days to laborious reconfiguration, dramatically raising overall cost of development and slowing time to market.

Spirent’s simulation software comes in three graded flavours, enabling you to choose the level of functionality you need. At the most advanced level, Spirent’s solutions give you complete control over test scenario parameters—with an intuitive interface and time-saving features developed over our 25 years at the cutting edge of satellite navigation and positioning testing:

• Work with repeatable signals and concrete figures, for accurate benchmarking and faster prototyping
• Increase process efficiency with technology built specifically for comprehensive GNSS testing
• Run simple tests out-of-the-box, rapidly configure advanced tests as and when you need
• Customise and standardise tests to meet industry or internal certification requirements

Accelerated Research and Development

The GNSS industry moves fast. With manufacturers of GNSS-enabled devices consistently demanding new capabilities and levels of performance from their GNSS-chipsets, getting an innovative, high performance product perfected and certified quickly can be crucial to its commercial success.

Spirent’s GNSS testing systems can dramatically accelerate GNSS chipset R&D, empowering you to:

• Model complex test scenarios quickly, with full, intuitive control of all test parameters
• Cut test cycle times with the ability to automate tests to run overnight
• Eliminate test write-up time with comprehensive automated reporting
• Record and Playback real-world signals for fast, accurate live sky testing in the lab

Hybrid Solutions

In the quest for the most accurate fix, location-aware devices increasingly rely on more than one source of positioning data.

Spirent is constantly developing new testing solutions to meet the needs of the R&D teams working at the vanguard of hybrid positioning technology.

• Add extensions and modules to enhance the capabilities of your GNSS testing systems
• Draw on the knowledge of Spirent engineers to build a bespoke testing solution
• Perform fast, accurate Wi-Fi positioning tests with integrated and standalone systems
• Take the lab outside, with portable, self-contained solutions and built-in interfaces

Future-Proof Investments

GPS may still be the primary concern for western GNSS chipset developers, but a sky full of new global constellations—from Galileo to GLONASS and Compass—are either in the latter stages of development or currently coming on stream, as well as numerous region-specific systems.

Multi-GNSS promises improved signal continuity, availability, integrity and accuracy. It’s important to know the R&D systems you are investing in today will still be just as valuable when Multi-GNSS becomes the industry standard.

Spirent’s GNSS simulators offer unrivalled investment protection, with the chance to:

• Start with a system that suits your needs, built on expert consultation
• Instantly upgrade software capabilities as and when you need
• Add satellite constellations when you move into new markets
• Test GNSS chipset performance with tomorrow’s constellations before they go live

Testing Performance, Not Budgets

Spirent’s GNSS simulators enable the vast majority of chipset testing to take place under controlled, repeatable conditions—and to produce meaningful, comparable results. Field testing, however, still remains an important stage in GNSS chipset R&D.

The cost of field testing can be minimised—and its usefulness increased—by recording live sky conditions and replaying them in the laboratory.

In this way, Spirent’s GNSS testing systems help reduce costs throughout the R&D process:

• Multiple software deployment options mean you only pay for the functionality you need
• Test automation and intuitive, comprehensive scenario modelling save R&D time and money
• Record and Playback systems lower the cost and raise the value of field testing
• Future-ready systems minimise future expenditure
