Validate GNSS Performance with Confidence
Real-world global navigation satellite system (GNSS) environments are unpredictable, making it difficult to verify how devices will perform once deployed. Signal variability, interference, and changing environmental conditions can introduce errors that are challenging to reproduce and diagnose.
Learn how realistic, repeatable GNSS testing helps engineers validation position, navigation, and timing performance, reduce developmental risk, and accelerate the delivery of reliable products to market.

The Pursuit of Realism Drives Better Outcomes
GNSS testing validates how position, navigation, and timing systems perform under real-world conditions. Simulation and record-and-playback bring those conditions into the lab with the repeatability, accuracy, and fidelity required for reliable development and validation. By accurately modeling transmitters, receivers, propagation channels, and vehicle dynamics, these technologies help bridge the gap between controlled lab testing and real-world performance.
Building a Realistic Test Environment
To create a realistic yet deterministic test environment, the following considerations are essential:
Signal Fidelity
Simulated GNSS signals should faithfully replicate real signals while providing control, repeatability, and modification capabilities.
Hardware and Software Integration
Tight coupling between software and hardware, ensuring seamless integration.
External Data Sources
Individual elements of the synthetic environment should closely mirror real-world characteristics and behavior.
Environmental Accuracy
Access to more accurate external data and models further enhances realism.
