The GSS7000 meets all performance specifications under all test conditions. Performance specifications are externally verified.

Generate up to 256 concurrent signals, with the power to model a wide range of parameters, such as

• Tx and Rx antenna gain and phase pattern
• Ionospheric and tropospheric effects
• Pseudorange ramps for RAIM testing and spoofing
• Satellite orbital data and navigation data
• vehicle motion

• Embedded interference generation capability
  • 8 transmitters and 16 interference channels in a single chassis
  • Maximum power level -47 dBm
  • User defined interference transmitter trajectory and antenna patterns
• The GSS7000 is capable of simulating real-world spoofing test cases, such as
  • meaconing attacks,
  • trajectory spoofing,
  • base station spoofing, and
  • satellite navigation data spoofing.

The 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.

The GSS7000 is designed to work seamlessly with a number of complementary tools. These include:

• Sim3D – realistic multipath testing with 3D models
• SimHIL – API with software interface for hardware-in-the-loop test integration.
• SimSENSOR – emulate the output of key MEMS sensors
