Software

GSS7000 is available with 3 levels of software built on Spirent’s positioning application engine to cater for all levels of test need and all budgets: SimGEN, SimREPLAYplus, and SimTEST.

Spirent’s flagship software platform, SimGEN, is the most powerful tool available to GNSS test and development teams.
SimREPLAYplus allows the replay of pre-defined test scenarios while providing a range of tools and capabilities to enhance usability before, during and after testing.
SimTEST is for essential testing, providing the capability needed to perform fundamental verification tests.

A GNSS receiver is typically part of a complex system of sensors, actuators, software applications, and algorithms, therefore developers need to ensure that an integrated product continues to meet standalone performance parameters. One key method employed is hardware-in-the-loop (HIL) testing. This white paper discusses the different approaches to HIL testing, and how latency impacts the […]
