High-Fidelity GNSS Simulation Without the Traditional Cost or Complexity

The GSG-8 Gen 2 GNSS Advanced Constellation Simulator is a next-generation, software-defined GNSS test system designed to deliver realistic, scalable, and cost-effective GNSS simulation for today’s most demanding applications.

Powered by Skydel GNSS Simulation Software, NVIDIA GPU acceleration, and commercial off-the-shelf (COTS) hardware, the GSG-8 Gen 2 replaces rigid, hardware-bound simulators with a flexible platform that evolves as your requirements grow.

Whether validating GNSS receivers, testing resilience against interference, or simulating complex multi-vehicle scenarios, the GSG-8 Gen 2 provides the realism and control needed to test with confidence.

Why the GSG-8 Gen 2

Software-Defined Architecture

Traditional simulators lock performance to fixed hardware. The GSG-8 Gen 2 uses GPU processing and SDR technology, allowing you to scale signal count, complexity, and performance simply by adding GPUs or SDRs.

Scalable Performance

• 200+ satellite signals from a single GPU

• 2000+ signals supported overall

• No channel-based licensing costs

• Expand capacity as testing needs evolve

Full Multi-Constellation Coverage

Simulate all major global and regional GNSS constellations, including GPS, Galileo, GLONASS, BeiDou, QZSS, NavIC, SBAS, Xona, and user-defined custom signals across L1, L2, and L5 bands.

Advanced Interference & Threat Simulation

Create controlled RF environments including jamming, spoofing, meaconing, and advanced interference with precise control and repeatability.

Built for Modern Test Workflows

• Pre-installed Ubuntu Linux or Windows 10

• APIs for Python, C#, and C++

• IQ file generation and playback

• Ideal for automation and CI/CD pipelines

One Platform. Multiple Markets.
