GP-Simulator 2

Application:
GNSS receivers used in critical applications—such as time synchronization, navigation, asset tracking, and drone control—must be resilient to intentional signal manipulation. With the growing availability of spoofing and jamming technologies, validating the protection mechanisms of GNSS-dependent systems is becoming a crucial step in product development and certification.

How GP-Simulator 2 helps:
GP-Simulator 2 enables precise simulation of GPS L1 spoofing scenarios in a lab or production environment. It supports both coherent and non-coherent spoofing with real-time control over simulated coordinates, time, PPS phase, and satellite parameters. Engineers can test how devices respond to false positioning, time drift, or signal hijacking without the need for outdoor testing or shielded rooms.

To simulate complete GNSS threat environments, GP-Jammer can be added. It allows generation of realistic jamming signals—including wideband, narrowband, and signal-matched interference—across three independent RF channels using Adalm Pluto SDRs. This combination makes it possible to test GNSS receivers under hybrid attack conditions, such as spoofing under jamming pressure, recovery from total signal loss, or simultaneous disruption across multiple constellations.

Together, GP-Simulator 2 and GP-Jammer  offer a comprehensive platform for evaluating GNSS receiver robustness, identifying weaknesses, and improving system-level protection. This solution is ideal for manufacturers, integrators, and security professionals working in telecom, energy, transportation, and autonomous systems.

Application:
GNSS-disciplined time servers are a cornerstone of modern infrastructure—used in telecommunications, data centers, power grids, financial systems, and transportation networks. Even minor disruptions in time synchronization due to spoofed GNSS signals can lead to cascading failures, service outages, and compliance violations.

How GP-Simulator 2 helps:
GP-Simulator 2 allows you to simulate controlled GPS spoofing attacks—shifting time, PPS phase, and satellite parameters in real time. This makes it possible to evaluate how precisely time servers respond to manipulation, and whether their internal protection algorithms are sufficient.

Application:
Electronics developers integrating GNSS modules into their designs (e.g., trackers, drones, IoT, vehicle 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

• 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 vehicle electronics, UAVs, asset trackers

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

• 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.
