GP-Simulator 2

Application:
GNSS receivers used for timing, navigation, asset tracking, and other critical applications must maintain predictable behavior under abnormal or degraded signal conditions. GP-Simulator 2 allows engineers to reproduce controlled GNSS test scenarios in a repeatable laboratory environment.

How GP-Simulator 2 helps:
GP-Simulator 2 supports precise GPS L1 signal simulation, including coherent and non-coherent spoofing test scenarios for receiver resilience evaluation. Engineers can configure simulated coordinates, time, PPS phase, satellite parameters, and signal transitions to evaluate how a receiver responds to abnormal GNSS conditions.

For broader RF susceptibility testing, GP-Simulator 2 can be used together with GP-Jammer in controlled laboratory environments. This enables combined testing with configurable RF interference waveforms and repeatable GNSS scenarios.

Together, GP-Simulator 2 and GP-Jammer provide a laboratory test platform for evaluating GNSS receiver robustness, identifying weaknesses, validating mitigation mechanisms, and measuring recovery behavior.

Application:
Electronics developers integrating GNSS modules into their designs (e.g., trackers, IoT devices, automotive electronics, and industrial systems) often need to verify performance and eliminate signal quality issues caused by PCB layout, interference, or component selection.

How GP-Simulator 2 helps:
By generating controlled, repeatable GPS signals directly in the lab, engineers can test GNSS functionality without relying on outdoor conditions or real satellites. This enables fast, precise debugging during schematic and layout development.

✅ Tasks it helps solve:

• Evaluate receiver sensitivity under known signal levels
• Detect impact of on-board EMI from DC/DC converters, microcontrollers, RF circuits
• Test performance with real-time position changes or trajectories
• Verify cold start time and positioning accuracy
• Assess PPS signal precision and stability under varying signal conditions

📏 What you can measure:

• Minimum signal level for stable satellite tracking
• Time-to-first-fix (TTFF) under different scenarios
• Positioning accuracy (static and dynamic)
• Phase offset and jitter of PPS output
• Reaction to simulated signal degradation or distortion

🎯 Key benefits:

• Debug GNSS issues at the engineer’s desk — no outdoor testing required
• Reduce development cycles and avoid costly post-production fixes
• Ensure consistent GNSS performance across prototypes
• Gain confidence in product quality before mass production

👥 Typical users:

• R&D teams at hardware startups and OEMs
• Developers of GNSS-enabled IoT devices
• Engineers working on automotive electronics, industrial devices, and asset-tracking systems

Application:
Electronics manufacturers who purchase GNSS modules from third-party suppliers need to ensure that every module meets performance and reliability standards before soldering it onto the main PCB. Quality issues such as counterfeit, ESD damage, or degraded sensitivity are common — and costly if detected too late.

How GP-Simulator 2 helps:
By simulating stable GPS signals in a controlled lab setup, GP-Simulator 2 allows manufacturers to quickly test large batches of GNSS modules under identical, repeatable conditions. This can be done either manually or as part of an automated test station using the API module.

✅ Tasks it helps solve:

• Validate module functionality before PCB mounting
• Measure signal acquisition time and sensitivity
• Identify defective, underperforming, or fake GNSS modules
• Compare modules from different suppliers
• Automate quality checks as part of incoming inspection or pre-assembly stage

📏 What you can measure:

• Cold start performance
• Number of satellites acquired and average SNR
• Time-to-first-fix under controlled signal levels
• Module PPS output presence and stability
• Stability of coordinates in static mode

🎯 Key benefits:

• Prevent defective GNSS modules from entering your production line
• Reduce rework, scrapping, and warranty claims
• Gain traceability and performance statistics for each module or supplier
• Save time by running high-volume, fast GNSS verification indoors
• Improve overall product quality and reduce manufacturing risk

👥 Typical users:

• EMS (Electronics Manufacturing Services) companies
• OEMs assembling GNSS-based products
• QA departments responsible for inbound component validation

Application:
After assembling GNSS-enabled products — such as vehicle trackers, telematics units, wearable devices, IoT sensors, or navigation systems — manufacturers need to confirm that the built-in GNSS module functions correctly in its final hardware and firmware configuration.

How GP-Simulator 2 helps:
GP-Simulator 2 allows production teams to simulate stable, repeatable GPS signals in a controlled indoor environment. Devices under test (DUTs) can be evaluated for GNSS performance without needing sky access or test driving. The same test scenario can be replayed across thousands of units with consistent results.
