GSS7000 Multi-GNSS Constellation Simulator SystemSpirent is a leading provider of simulation and test solutions for GPS/GNSS satellite-based navigation and positioning in unmanned systems. Our products will help you overcome the challenges of developing autonomous unmanned vehicles, such as self-knowledge of position and attitude, safe and accurate navigation, and recovery from signal loss, as well as operation in harsh environments.

Incorporating our test and simulation solutions into your unmanned systems development will provide you with many advantages over using “live-sky” signals, including full control over test signals and parameters, repeatability, and simulation of signals from future constellations.

GSS7000 Multi-GNSS Constellation Simulator System

The GSS7000 Multi-GNSS Constellation Simulator is an entry-level test tool that allows you to verify the positioning performance of your unmanned vehicles under controlled, repeatable conditions. The accurate, powerful system allows simultaneous GNSS signals (supporting GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS) across a wide range of frequencies, enabling you to develop a test regime that provides maximum rigour with minimum time and cost.

  • Supports GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS L1/E1/B1, L2/B2 and L5/E5 signals
  • Up to 256 channels per system, flexibly allocated across constellations
  • Selection of scenario generation and simulation control software available
  • Single RF version, or dual RF version for differential-GNSS and multi-vehicle simulation
  • Availability of Single Channel Utility for cost-effective production line quality testing.

GSS9000 GNSS Constellation Simulator

The GSS9000 GNSS Constellation Simulator is our most advanced test solution, providing the sophisticated and accurate testing required for the precise positioning, navigation and timing systems of unmanned vehicles in military, aerospace and research applications. The GNSS9000 supports all signals and frequencies from all GNSS constellations, both present and under development, including regional augmentation systems and classified/restricted signals.

GSS9000 GNSS Constellation Simulator

With support for multiple signal combinations, multi-antenna and multi-vehicle systems, and interference, jamming and spoofing tests, the GNSS9000 meets every conceivable testing need for unmanned vehicle GNSS technology.

  • Generates all carriers, ranging codes and data streams for the GPS, GLONASS, Galileo and BeiDou GNSS systems, plus SBAS, QZSS, IRNSS and CAPS regional/augmentation systems
  • 1000Hz Simulation Iteration Rate (SIR) and Hardware Update Rate (HUR), enabling real-time remote control and trajectory delivery
  • 160 channels plus 640 embedded multipath channels across 10 independent frequencies
  • Single RF version, or dual RF version for differential-GNSS and multi-vehicle simulation
  • On-the-fly re-configuration of constellation and signal configurations
  • Selection of simulation, modelling and testing software available

GSS6450 RF Record & Playback System

The GSS6450 takes RF record & playback systems to a whole new level of performance and flexibility. Battery powered and housed in a small and portable case, the GSS6450 can record any RF in the 100MHz-6,000MHz frequency range – including any current GNSS signal, 2.5GHz and 5GHz WiFi, and Cellular.

GSS6450 RF Record & Playback System

With the capability to record at up to 16 bits ‘I’ & 16 bits ‘Q and the flexibility to select any 80MHz band within the frequency range, the GSS6450 can be configured to meet your testing requirements – even as they evolve.

  • 3 independent RF ports
  • Multiple constellations and frequencies
  • Built-in real-time spectrum analyser
  • Touchscreen / WiFi / Web Server / Script control
  • 216 x 200 x 76 mm – weighing just 2.2kg
  • Flexible product structure.
