Multi-GNSS Constellation Simulators, Signal Generators and Record/Playback Systems


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

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.

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.

GSS9000 GNSS Constellation Simulator

  • 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

GSS6300 GPS/GNSS Signal Generator

The GSS6300 GPS/GNSS Signal Generator allows you to perform fast, accurate testing of multiple GNSS signals in a volume production test environment. The GSS6300 applies controllable, repeatable test signals directly to the product under test, thus avoiding problems with the electrically noisy conditions of a production environment and providing greater end-of-production line quality control than usage of uncontrollable “live-sky” signals.

GSS6300 GNSS Signal Generator

  • Single channel GPS/SBAS/QZSS L1 C/A and/or GLONASS L1 C/A and/or BeiDou-2 B1 and/or Galileo E1 signals in one chassis
  • IEEE-488, USB or RS-232 control interfaces
  • Spirent SimCHAN software included to enable real-time user control

GSS6425 Multiple Constellation Record & Playback System

The GSS6425 records real-world GNSS signals, allowing you to cut down on test flights and re-use captured flight data in the lab. This avoids slow, non-repeatable testing with live signals, thus saving you travel and engineering costs and resulting in consistent, cost-effective results.

The self-contained unit is available in several models, ranging from GPS L1 only to full constellation selection (GPS/SBAS/QZSS L1/L2/L5, Galileo E1/E5a/E5b/E6, BeiDou B1/B2/B3, GLONASS L1/L2/L3).

GSS6425 Multiple Constellation Record & Playback System

  • Multiple constellations and frequencies
  • Self-contained portable unit – no PC or external drives required
  • Internal 1TB hard drive, with additional removable 1TB hard drive supplied
  • Control from front panel over WiFi, webserver or scripts
  • Power from internal battery (up to 1.5hr) or vehicle DC power adapter
  • Records up to three frequencies at any one time with 30MHz bandwidth or two at 50MHz
